# AVFS (AV FileSystem)

AV FileSystem is based on AVFS and shares most of its source code and functionality. This package has several uses. It can easily make a script file openable by any application, as it appears like a real, uncompressed avi file. It can also be used to bridge the 32/64 bit gap, since a plain file can always be read.

To use it simply run `avfs` in the `core32` or `core64` directories with the script name as argument. This will create a virtual file in `C:\\Volumes`.

## Avisynth Support

Note that this AVFS version is also compatible with Avisynth 2.6 and Avisynth+. When using Avisynth+ higher bitdepth output is also supported. The easiest way to obtain a recent version is to extract `avfs.exe` from the portable VapourSynth archives.
