Hgfs is a read-only filesystem interface to Mercurial repositories. The interface gives access to the commit message, manifest, and files of each revision, and to .tgz's of each revision (the .tgz's are generated as they are read). The filesystem is a front-end for the Mercurial library that comes with it. All code is written in Limbo, for Inferno.
Lessfs is a high performance inline data deduplicating file system for Linux. Lessfs complies to the POSIX standard and is very useful for backup purposes as well as providing storage for virtual machine images. Although lessfs is a file system that is implemented in user space with FUSE, it offers decent performance. Lessfs is capable of handling data rates up to 350MB/sec. It supports filesystem encryption.
qemu-diskp is a FUSE mounter to mount virtual disk images. Most virtual machine environments provide a raw disk model to the operating system(s) they host. Typically this raw disk is stored as a simple file rather than a dedicated hardware device. Since the file is a bit-image of what would normally be an actual hardware disk, it holds a complete disk layout. This makes it difficult to mount or manage each of the filesystems within that virtual disk image by the host machine, especially if the file for the image is itself a composite, such as a qemu qcow2 file. This project provides a FUSE based filesystem that presents each of the partitions in a full disk image as individual files. Those files may then be accessed by user-level applications (e.g. fsck or mke2fs) or loop-back mounted, enabling normal file system tools to examine or modify their contents.
sortsamples is a utility that solves the problem of having many sample CD/sample library directories with each having kick, hi-hat, snare, etc. folders (leading to sampledirectorychaosmadness). With many sample directories, you ll be slapped around many directories hunting for kicks/hi-hats etc. This utility creates symbolic links to directories which are similar. This way, you can have all your kick. It was made because external Sample organizing utilities can also become a pain, because usually your DAW also has a sample browser in it. It would be nice to have structure at the source: the filesystem. This is a crazy effort to combine similar folders and categorize automatically.
