CFAT File System: Because Re-inventing the Wheel Is Educational.

Check out the repo for more details.

Here’s the scoop:

  1. What It Does

    • Full CRUD on files and directories (create, read, update, delete), because obviously you need that.
    • Bash around in an interactive shell: ls, cd, tree, cat, rm, mkdir—all your favorite file-system rituals.
    • Slice out files with extract or mount the whole thing to a folder and pretend it’s “real.”

  2. How to Get It

    • sudo apt-get install libfuse-dev pkg-config on Debian-y systems.
    • make (or gcc cfs.c -o cfs \pkg-config fuse –cflags –libs`` if you’re feeling old-school).

  3. How to Use It

    • Create: ./cfs -f mydisk.CFAT -c
    • List: ./cfs -f mydisk.CFAT -l
    • Add: ./cfs -f mydisk.CFAT -a report.pdf -i /docs/
    • Mount: ./cfs -f mydisk.CFAT -m /mnt/fat …then fusermount -u /mnt/fat when you’re done janking around.
    • Interactive: ./cfs -f mydisk.CFAT -I—type help to see all the shady commands.

  4. The Inevitable Caveats

    • 11-char filename limit (yes, really).
    • Large files (>131 KB) might trigger undocumented gremlins.
    • Editing via Vim/Emacs can segfault; Nano is your best friend.
    • “Transport endpoint is not connected”? That’s FUSE yelling at you—just rerun fusermount -d and remount.

In short, CFAT is absurdly instructive, mildly stable, and totally not where you should archive your thesis. Proceed at your own peril—and enjoy the ride through user-space madness.
