Zio provides a simple, powerful, cross-platform filesystem abstraction for .NET with many built-ins filesystems.

Features

• Compatible with .NET 4.6+, netstandard2.0, netstandard2.1 and net7.0
• API providing all operations provided by the regular System.IO API (e.g File.Move, Directory.Delete... etc.)
  • Allowing atomic filesystem operations (e.g File.Replace...)
• A simple interface abstraction IFileSystem
• Supports for filesystem watcher through the IFileSystem.Watch method and the IFileSystemWatcher interface
  • For all builtin filesystems (aggregates, memory...etc.)
• All paths are normalized through a lightweight uniform path struct UPath
• Multiple built-ins filesystems:
  • PhysicalFileSystem to access the physical disks, directories and folders.
    • With uniform paths, this filesystem on Windows is working like on a Windows Subsystem Linux (WSL), by remapping drives to mount directory (e.g path /mnt/c/Windows equivalent to C:\Windows)
  • MemoryFileSystem to access a filesystem in memory:
    • Trying to be 100% compatible with a true PhysicalFileSystem (including exceptions)
    • Efficient concurrency with a per node (file or directory) locking mechanism
    • A safe hierarchical locking strategy (following Unix kernel recommendations for directory locking)
    • Support for FileShare.Read, FileShare.Write and FileShare.ReadWrite
    • Internally support for filesystem atomic operations (File.Replace)
  • ZipArchiveFileSystem to access zip archives:
    • This filesystem is a wrapper around the ZipArchive class
    • It can work in case sensitive and case insensitive mode
    • Support for FileShare.Read with ZipArchiveMode.Read
  • On top of these final filesystem, you can compose more complex filesystems:
    • AggregateFileSystem providing a read-only filesystem aggregating multiple filesystem that offers a merged view
    • MountFileSystem to mount different filesystems at a specific mount point name
    • SubFileSystem to view a sub-folder of another filesystem as if it was a root / directory
    • ReadOnlyFileSystem to interact safely with another filesystem in read-only mode
• Higher level API similar to FileSystemEntry, FileEntry and DirectoryEntry offering a similar API to their respective FileSystemInfo, FileInfo, DirectoryInfo

Usage

Accessing a physical filesystem:

var fs = new PhysicalFileSystem();
foreach(var dir in fs.EnumerateDirectories("/mnt/c"))
{
    // ...
}

Using an in-memory filesystem:

var fs = new MemoryFileSystem();
fs.WriteAllText("/temp.txt", "This is a content");
if (fs.FileExists("/temp.txt"))
{
    Console.WriteLine("The content of the file:" + fs.ReadAllText("/temp.txt"))
}

The following documentation provides more information about the API and how to use it.
