UnFuseFS

UnFuseFS is a simple FUSE implementation which divides the input file into equal-sized chunks, or to put it simply, it takes a file and cuts it up into multiple files in a virtual directory without taking any additional space on disk.

Usage

$ stat foobar
  File: foobar
  Size: 4000000000      Blocks: 0          IO Block: 4096   regular file
...

$ unfusefs foobar
Chunk Size: 1.9 GiB (2000000000 bytes)
Mounting "foobar" to "/tmp/split/foobar.split"

$ ls foobar.split
foobar.01  foobar.02

$ unfusefs --help # For more info

Build

Use your usual Cargo commands or run ./build-release.sh to build a size-optimized release binary, you can also optionally set TARGET_PLATFORM for cross-compiliation.

NOTE: libfuse is not required since this project uses the fuser library to implement the FS in Rust entirely :)
