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

• Compatible with.NET 4.6+,netstandard2.0,netstandard2.1 andnet7.0
• 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 abstractionIFileSystem
• Supports for filesystem watcher through theIFileSystem.Watch method and theIFileSystemWatcher interface
  • For all builtin filesystems (aggregates, memory...etc.)
• All paths are normalized through a lightweight uniform path structUPath
• 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 toC:\Windows)
  • MemoryFileSystem to access a filesystem in memory:
    • Trying to be 100% compatible with a truePhysicalFileSystem (including exceptions)
    • Efficient concurrency with a per node (file or directory) locking mechanism
    • A safe hierarchical locking strategy (followingUnix kernel recommendations for directory locking)
    • Support forFileShare.Read,FileShare.Write andFileShare.ReadWrite
    • Internally support for filesystem atomic operations (File.Replace)
  • ZipArchiveFileSystem to access zip archives:
    • This filesystem is a wrapper around theZipArchive class
    • It can work in case sensitive and case insensitive mode
    • Support forFileShare.Read withZipArchiveMode.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 toFileSystemEntry,FileEntry andDirectoryEntry offering a similar API to their respectiveFileSystemInfo,FileInfo,DirectoryInfo

Accessing a physical filesystem:

varfs=newPhysicalFileSystem();foreach(vardirinfs.EnumerateDirectories("/mnt/c")){// ...}

Using an in-memory filesystem:

varfs=newMemoryFileSystem();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.

Thedocumentation is directly available as part of this repository in the/doc folder.

Zio is available as a NuGet package:

In order to build Zio, you need to install Visual Studio 2022 with latest.NET 7.0
