[ Modified from https://github.com/kees1948/UniFLEX/tree/master/Linux-tools/Fuse4UNIFLEX to add:

• long filename support
• compiling for MacOS (macFUSE) ]

This is an implementation of Fuse (Filesystem in User space) that allows you to mount UniFLEX formatted .dsk images and have full access to the contents.

mount the UniFLEX filesystem (example)

fuse_uf wd0.dsk UF

Assuming that mount point UF (a directory) already existed.

df may give: fuse_uf 14586 2432 12154 17% /home/kees/fuse/UF

ls -l UF may give you:

You can add/delete files, create/remove directories, change permissions, change owner, create device files (but only if mounted as root and run mknod as root!)

I created it to ease my access to the UniFLEX disk images. The Fuse implementation may (will) have bugs but it is in a very usable state.

Building it goes like:

apt-get install libfuse-dev

gcc -g -Wall fuse_uf.c -fms-extensions pkg-config fuse --cflags --libs -o fuse_uf

warnings may be ignored

If you plan to run gdb with it, your set args should be something like

set args  -s -f \
set breakpoints
run

If you need to exit gdb, don't forget to run fusermount -u

fusermount -u will unmount the UniFLEX disk image.

Have Fun!

[2022-11-23] I took the time to figure out why it would not build properly on Linux 64 bit. You may ignore the warnings the compiler may throw at you. It turns out that the size of the UniFLEX SIR was defined wrong. Corrected that. Now I can build and use fuse_uf on a 64 bit Linux again.

[2025-01-03] After moving to a 64 bit environment with Ubuntu, I got a newer compiler and libraries.

cc fuse_uf.c -D_FILE_OFFSET_BITS=64 `pkg-config fuse --cflags --libs`  -o fuse_uf
