Major update: Enhanced documentation, comprehensive examples, and fixed remaining issues

- Updated README.md with modern feature descriptions and comprehensive overview
- Enhanced docs/USAGE.md with advanced object listing, directory management, and chunked operations
- Created examples/ directory with 6 comprehensive example scripts:
  * 01-Basic-Operations.ps1 - Fundamental operations for beginners
  * 02-Advanced-Object-Listing.ps1 - Filtering, sorting, and pagination
  * 03-Directory-Management.ps1 - Nested directory structures and organization
  * 04-Chunked-Operations.ps1 - Large file handling with performance optimization
  * 05-Bulk-Operations.ps1 - Batch processing and automation workflows
  * 06-Enterprise-Automation.ps1 - Enterprise monitoring, reporting, and compliance
- Added comprehensive examples/README.md with usage patterns and best practices
- Fixed directory creation warnings (now clean verbose logging)
- Implemented missing Get-MinIOObject cmdlet with full filtering/sorting capabilities
- Added timing and performance metrics to all operations
- Enhanced chunked operations with multi-layer progress tracking
- Improved error handling and resource cleanup
- Removed temporary test files and cleaned up repository structure
- All examples use proper PowerShell output (no Write-Host usage)
- Professional logging with timestamps and structured output

### Import the Module ### Import the Module
```powershell ```powershell
# Import the module # Import the module from the Module directory
Import-Module .\PSMinIO.psd1 Import-Module .\Module\PSMinIO\PSMinIO.psd1
# Verify the module is loaded # Verify the module is loaded and check available cmdlets
Get-Module PSMinIO Get-Module PSMinIO
Get-Command -Module PSMinIO
``` ```
## Configuration ## Connection Management
### Basic Configuration ### Establishing Connections
PSMinIO uses a modern connection-based approach with the `Connect-MinIO` cmdlet:
```powershell ```powershell
# Set up MinIO connection # Connect to MinIO server with SSL
Set-MinIOConfig -Endpoint "minio.example.com:9000" ` $connection = Connect-MinIO -Endpoint "https://minio.example.com" -AccessKey "your-access-key" -SecretKey "your-secret-key"
-AccessKey "your-access-key" `
-SecretKey "your-secret-key" `
-UseSSL
# For local development (no SSL) # Connect to local MinIO (no SSL)
Set-MinIOConfig -Endpoint "localhost:9000" ` $connection = Connect-MinIO -Endpoint "http://localhost:9000" -AccessKey "minioadmin" -SecretKey "minioadmin"
-AccessKey "minioadmin" `
-SecretKey "minioadmin" ` # Connect with custom port
-NoSSL $connection = Connect-MinIO -Endpoint "https://minio.example.com:9443" -AccessKey "your-access-key" -SecretKey "your-secret-key"
```
### Connection Options
```powershell
# Skip SSL certificate validation (for self-signed certificates)
$connection = Connect-MinIO -Endpoint "https://minio.internal.com" -AccessKey "key" -SecretKey "secret" -SkipCertificateValidation
# Connection with region specification
$connection = Connect-MinIO -Endpoint "https://s3.amazonaws.com" -AccessKey "key" -SecretKey "secret" -Region "us-west-2"
``` ```

-Force -Force
``` ```
## Advanced Object Listing
The `Get-MinIOObject` cmdlet provides powerful filtering, sorting, and pagination capabilities:
### Basic Object Listing
```powershell
# List all objects in a bucket
Get-MinIOObject -BucketName "my-bucket"
# List objects with a specific prefix
Get-MinIOObject -BucketName "my-bucket" -Prefix "documents/"
# List objects recursively (default behavior)
Get-MinIOObject -BucketName "my-bucket" -Prefix "logs/" -Recursive
# List objects non-recursively (current level only)
Get-MinIOObject -BucketName "my-bucket" -Prefix "logs/" -Recursive:$false
```
### Advanced Filtering
```powershell
# Get a specific object by exact name
Get-MinIOObject -BucketName "my-bucket" -ObjectName "documents/report.pdf"
# List only files (exclude directory markers)
Get-MinIOObject -BucketName "my-bucket" -ObjectsOnly
# Include object versions (for versioned buckets)
Get-MinIOObject -BucketName "my-bucket" -IncludeVersions
# Limit the number of results
Get-MinIOObject -BucketName "my-bucket" -MaxObjects 50
```
### Sorting Options
```powershell
# Sort by name (ascending - default)
Get-MinIOObject -BucketName "my-bucket" -SortBy "Name"
# Sort by name (descending)
Get-MinIOObject -BucketName "my-bucket" -SortBy "Name" -Descending
# Sort by file size (largest first)
Get-MinIOObject -BucketName "my-bucket" -SortBy "Size" -Descending
# Sort by last modified date (newest first)
Get-MinIOObject -BucketName "my-bucket" -SortBy "LastModified" -Descending
# Sort by ETag
Get-MinIOObject -BucketName "my-bucket" -SortBy "ETag"
```
### Complex Queries
```powershell
# Find large files in a specific directory
Get-MinIOObject -BucketName "media" -Prefix "videos/" -SortBy "Size" -Descending -MaxObjects 10
# Get recent files only
$recentFiles = Get-MinIOObject -BucketName "logs" -SortBy "LastModified" -Descending -MaxObjects 20
# Find files by pattern using PowerShell filtering
Get-MinIOObject -BucketName "documents" | Where-Object { $_.Name -like "*.pdf" -and $_.Size -gt 1MB }
# Get directory structure overview
Get-MinIOObject -BucketName "my-bucket" | Group-Object { ($_.Name -split '/')[0] } | Format-Table Name, Count
```
## Directory and Folder Management
### Creating Directory Structures
```powershell
# Create explicit folder structures
New-MinIOFolder -BucketName "my-bucket" -FolderName "projects/web-app/src"
New-MinIOFolder -BucketName "my-bucket" -FolderName "projects/web-app/docs"
# Create multiple folder levels at once
New-MinIOFolder -BucketName "my-bucket" -FolderName "company/departments/engineering/teams/backend"
```
### Automatic Directory Creation
```powershell
# Upload files with automatic directory creation using BucketDirectory
New-MinIOObject -BucketName "my-bucket" -Files "report.pdf" -BucketDirectory "documents/2025/january"
# Create nested directory structures automatically
New-MinIOObject -BucketName "my-bucket" -Files "config.json" -BucketDirectory "projects/web-app/config/production"
```
### Directory-Based Operations
```powershell
# List all directories (folder markers)
Get-MinIOObject -BucketName "my-bucket" | Where-Object { $_.IsDirectory }
# List files in a specific directory
Get-MinIOObject -BucketName "my-bucket" -Prefix "documents/2025/" -ObjectsOnly
# Organize files by date-based directories
$today = Get-Date -Format "yyyy/MM/dd"
New-MinIOObject -BucketName "logs" -Files "app.log" -BucketDirectory "daily-logs/$today"
```
## Chunked Operations
### Chunked Uploads
```powershell
# Upload large files with chunked transfer
New-MinIOObjectChunked -BucketName "media" -Files "large-video.mp4" -ChunkSize 10MB
# Upload with custom chunk size and directory
New-MinIOObjectChunked -BucketName "backups" -Files "database-backup.sql" -ChunkSize 5MB -BucketDirectory "daily-backups/$(Get-Date -Format 'yyyy-MM-dd')"
# Upload multiple large files
New-MinIOObjectChunked -BucketName "media" -Files @("video1.mp4", "video2.mp4") -ChunkSize 10MB -BucketDirectory "videos/uploads"
```
### Chunked Downloads
```powershell
# Download large files with chunked transfer
Get-MinIOObjectContentChunked -BucketName "media" -ObjectName "large-video.mp4" -FilePath "C:\Downloads\video.mp4" -ChunkSize 10MB
# Download with progress tracking
Get-MinIOObjectContentChunked -BucketName "backups" -ObjectName "large-backup.zip" -FilePath "C:\Restore\backup.zip" -ChunkSize 5MB
```
### Chunk Size Guidelines
```powershell
# Recommended chunk sizes based on file size:
# Files < 10MB: Use regular upload/download
# Files 10MB - 100MB: Use 1-5MB chunks
# Files 100MB - 1GB: Use 5-10MB chunks
# Files > 1GB: Use 10-50MB chunks
# Example with optimal chunk size selection
$fileSize = (Get-Item "large-file.zip").Length
$chunkSize = if ($fileSize -lt 10MB) { 1MB }
elseif ($fileSize -lt 100MB) { 5MB }
elseif ($fileSize -lt 1GB) { 10MB }
else { 25MB }
New-MinIOObjectChunked -BucketName "uploads" -Files "large-file.zip" -ChunkSize $chunkSize

# PSMinIO Examples
This directory contains comprehensive examples demonstrating various PSMinIO capabilities and usage patterns.
## Prerequisites
Before running these examples:
1. **Install PSMinIO**: Import the module using `Import-Module ..\Module\PSMinIO\PSMinIO.psd1`
2. **MinIO Server**: Have access to a MinIO server or compatible S3 service
3. **Credentials**: Update the connection details in each script with your actual values:
```powershell
$endpoint = "https://your-minio-server.com"
$accessKey = "your-access-key"
$secretKey = "your-secret-key"
```
## Example Scripts
### 01-Basic-Operations.ps1
**Fundamental MinIO operations for beginners**
Demonstrates:
- Connecting to MinIO server
- Creating and managing buckets
- Basic file upload and download
- Object listing and verification
- Clean resource management
**Best for**: First-time users, basic automation scripts
---
### 02-Advanced-Object-Listing.ps1
**Comprehensive object listing and filtering capabilities**
Demonstrates:
- Advanced filtering with prefixes
- Sorting by multiple criteria (Name, Size, LastModified, ETag)
- Result pagination with MaxObjects
- Files-only filtering (excluding directories)
- Complex query combinations
**Best for**: Data discovery, content management, reporting
---
### 03-Directory-Management.ps1
**Creating and managing directory structures**
Demonstrates:
- Explicit folder creation with New-MinIOFolder
- Automatic directory creation with BucketDirectory
- Multi-level nested directory structures
- Directory-based file organization
- Date-based directory patterns
**Best for**: Organized file storage, hierarchical data management
---
### 04-Chunked-Operations.ps1
**Large file handling with chunked transfers**
Demonstrates:
- Chunked uploads with configurable chunk sizes
- Chunked downloads for large files
- Multi-layer progress tracking
- Performance comparison (regular vs chunked)
- Chunk size optimization guidelines
**Best for**: Large file transfers, bandwidth optimization, resume capability
---
### 05-Bulk-Operations.ps1
**Batch processing and bulk file operations**
Demonstrates:
- Multiple file uploads to organized directories
- Bulk download operations with filtering
- File analysis and statistics
- Pattern-based file processing
- Selective cleanup operations
**Best for**: Data migration, batch processing, automated workflows
---
### 06-Enterprise-Automation.ps1
**Enterprise-grade automation and monitoring**
Demonstrates:
- Infrastructure health checks
- Storage statistics and monitoring
- Automated backup operations
- Data lifecycle management
- Security and compliance auditing
- Performance monitoring
- HTML report generation
**Best for**: Enterprise environments, monitoring systems, compliance reporting
## Usage Patterns
### Quick Start
```powershell
# Run a basic example
.\01-Basic-Operations.ps1
```
### Customization
Each script includes configuration variables at the top. Modify these for your environment:
```powershell
# Connection details
$endpoint = "https://your-minio-server.com"
$accessKey = "your-access-key"
$secretKey = "your-secret-key"
# Optional: Bucket naming
$bucketName = "your-custom-bucket-name"
```
### Integration
These examples can be integrated into larger automation workflows:
```powershell
# Source common functions
. .\examples\06-Enterprise-Automation.ps1
# Use specific functions in your scripts
Write-Log "Starting custom automation"
$stats = Get-MinIOStats
```
## Common Scenarios
### Development Environment Setup
```powershell
# Local MinIO setup
$endpoint = "http://localhost:9000"
$accessKey = "minioadmin"
$secretKey = "minioadmin"
```
### Production Environment
```powershell
# Production setup with SSL
$endpoint = "https://minio.company.com"
$accessKey = $env:MINIO_ACCESS_KEY
$secretKey = $env:MINIO_SECRET_KEY
```
### AWS S3 Compatibility
```powershell
# AWS S3 setup
$endpoint = "https://s3.amazonaws.com"
$accessKey = $env:AWS_ACCESS_KEY_ID
$secretKey = $env:AWS_SECRET_ACCESS_KEY
```
## Best Practices
### Error Handling
All examples include comprehensive error handling:
```powershell
try {
# MinIO operations
} catch {
"❌ Error: $($_.Exception.Message)"
} finally {
# Cleanup operations
}
```
### Resource Cleanup
Examples automatically clean up created resources:
- Remove test buckets
- Delete uploaded files
- Clean local temporary files
### Logging
Enterprise examples include structured logging:
```powershell
function Write-Log {
param([string]$Message, [string]$Level = "INFO")
$timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
"[$timestamp] [$Level] $Message"
}
```
### Performance Considerations
- Use chunked operations for files > 10MB
- Implement appropriate chunk sizes based on network conditions
- Monitor transfer speeds and adjust accordingly
## Troubleshooting
### Connection Issues
- Verify endpoint URL and port
- Check SSL/TLS configuration
- Validate access credentials
- Test network connectivity
### Permission Issues
- Ensure proper bucket permissions
- Verify access key has required privileges
- Check bucket policies if applicable
### Performance Issues
- Adjust chunk sizes for large files
- Monitor network bandwidth
- Consider parallel operations for bulk transfers
## Contributing
When adding new examples:
1. Follow the existing naming convention
2. Include comprehensive error handling
3. Add resource cleanup
4. Document the example purpose and usage
5. Update this README with the new example
## Support
For issues with these examples:
- Check the main [PSMinIO documentation](../docs/USAGE.md)
- Review error messages and logs
- Verify your MinIO server configuration
- Test with basic operations first

System.Runtime.CompilerServices.Unsafe Polyfill for .NET Framework 4.0

Provides the System.Runtime.CompilerServices.Unsafe class, which provides generic, low-level functionality for manipulating pointers.
Commonly Used Types:
- System.Runtime.CompilerServices.Unsafe
------------
This package adds support for System.Runtime.CompilerServices.Unsafe on .NET Framework 4.0.
This is a compilation using the System.Runtime.CompilerServices.Unsafe source code from .NET Core 6.0.28. All tests are passing.
This is not meant to be an upgrade to System.Runtime.CompilerServices.Unsafe 6.0.0, it is simply to add support on the `net40` target for all of the existing APIs in System.Runtime.CompilerServices.Unsafe 6.0.0. It is recommended to use the official release of System.Runtime.CompilerServices.Unsafe on newer versions of .NET.
## Interop with System.Runtime.CompilerServices.Unsafe on Targets > net40
Since the runtime for `net40` hasn't been supported for many years, most likely you will be using a newer runtime with this library. But you may be interoperating with other components that target System.Runtime.CompilerServices.Unsafe, which will cause type collisions by default.
In this case, it is recommended to remove System.Runtime.CompilerServices.Unsafe from compilation and add NetFx.System.Runtime.CompilerServices.Unsafe in its place. Add the following to your `.csproj` or `.vbproj` file. This example is for using `net452`.
```xml
<ItemGroup Condition=" '$(TargetFramework)' == 'net452' ">
<!-- ExcludeAssets=compile removes the dependency from being referenced.
ExcludeAssets=runtime removes the dependency from the build output. -->
<PackageReference Include="System.Runtime.CompilerServices.Unsafe"
Version="6.0.0"
ExcludeAssets="compile;runtime" />
<PackageReference Include="NetFx.System.Runtime.CompilerServices.Unsafe"
Version="4.0.0" />
</ItemGroup>
```
> **NOTE:** Only SDK-style projects are supported using this method.
For transitive dependencies (that is, dependencies that are not directly referenced) that have a `net40` target, consider [forcing a specific target framework](https://duanenewman.net/blog/post/forcing-a-specific-target-platform-with-packagereference/).
## Saying Thanks
If you find this library to be useful, please star us [on GitHub](https://github.com/NightOwl888/NetFx.Polyfills) and consider a sponsorship so we can continue bringing you great free tools like this one. It really would make a big difference!

6. EXPORT RESTRICTIONS. The software is subject to United States export laws and regulations. You must comply with all domestic and international export laws and regulations that apply to the software. These laws include restrictions on destinations, end users and end use. For additional information, see www.microsoft.com/exporting.
7. SUPPORT SERVICES. Because this software is “as is,” we may not provide support services for it.
8. ENTIRE AGREEMENT. This agreement, and the terms for supplements, updates, Internet-based services and support services that you use, are the entire agreement for the software and support services.
9. APPLICABLE LAW.
a. United States. If you acquired the software in the United States, Washington state law governs the interpretation of this agreement and applies to claims for breach of it, regardless of conflict of laws principles. The laws of the state where you live govern all other claims, including claims under state consumer protection laws, unfair competition laws, and in tort.
b. Outside the United States. If you acquired the software in any other country, the laws of that country apply.
10. LEGAL EFFECT. This agreement describes certain legal rights. You may have other rights under the laws of your country. You may also have rights with respect to the party from whom you acquired the software. This agreement does not change your rights under the laws of your country if the laws of your country do not permit it to do so.
11. DISCLAIMER OF WARRANTY. THE SOFTWARE IS LICENSED “AS-IS.” YOU BEAR THE RISK OF USING IT. MICROSOFT GIVES NO EXPRESS WARRANTIES, GUARANTEES OR CONDITIONS. YOU MAY HAVE ADDITIONAL CONSUMER RIGHTS OR STATUTORY GUARANTEES UNDER YOUR LOCAL LAWS WHICH THIS AGREEMENT CANNOT CHANGE. TO THE EXTENT PERMITTED UNDER YOUR LOCAL LAWS, MICROSOFT EXCLUDES THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.
FOR AUSTRALIA YOU HAVE STATUTORY GUARANTEES UNDER THE AUSTRALIAN CONSUMER LAW AND NOTHING IN THESE TERMS IS INTENDED TO AFFECT THOSE RIGHTS.
12. LIMITATION ON AND EXCLUSION OF REMEDIES AND DAMAGES. YOU CAN RECOVER FROM MICROSOFT AND ITS SUPPLIERS ONLY DIRECT DAMAGES UP TO U.S. $5.00. YOU CANNOT RECOVER ANY OTHER DAMAGES, INCLUDING CONSEQUENTIAL, LOST PROFITS, SPECIAL, INDIRECT OR INCIDENTAL DAMAGES.
This limitation applies to
· anything related to the software, services, content (including code) on third party Internet sites, or third party programs; and
· claims for breach of contract, breach of warranty, guarantee or condition, strict liability, negligence, or other tort to the extent permitted by applicable law.
It also applies even if Microsoft knew or should have known about the possibility of the damages. The above limitation or exclusion may not apply to you because your country may not allow the exclusion or limitation of incidental, consequential or other damages.
