The Virtual File System makes it possible to manage files that do not exist on a physical file system (e.g. disk).

• The VirtualFileSystem can be extended by additional IVirtualFileProviders.
• Out-of-the-box, Microsoft.Extensions.FileProviders.Composite, Microsoft.Extensions.FileProviders.Embedded and Microsoft.Extensions.FileProviders.Physical are integrated.
• Virtual files can be used just like static files in an application.
• JavaScript, CSS, image files and all other file types can be embedded into assemblies and used just like the static files.
• An application (or library) can override an embedded file just by placing a static file with the same name and extension into the same folder of the virtual file system.

The library is a modified version of Volo.Abp.VirtualFileSystem 7.0 Modifications to the source code were made by axuno in 2020-23. Changes focused on:

• Decouple Volo.Abp.VirtualFileSystem from all dependencies of the Abp Framework
• Use Microsoft DependencyInjection instead of AutoFac
• Add a workaround, so that VirtualFileProvider will also find existing directories returned from PhysicalFileProvider. This means, that VirtualFileProvider behaves the same, never mind whether files are retrieved using EmbeddedFileProvider or PhysicalFileProvider.
• Change of namespaces

• Install the NuGet package
• Read the Virtual File System wiki
