    I've been having this problem for a while now on my iMac (OSX 10.6.3) where a file would just rename itself into something like "FULLM~20.MKV" after I rename a different file within the same folder.
    It's occurred in several folders and is really annoying because I don't know what the original filenames are and messes up my organization.
    I took note of some occurrences below. If I recall correctly, trying to fix the messed up filename sometimes works but it eventually gets messed up again. It's not limited to video files only, I've seen it happen to a jpg at least once.

    Renaming
    "✘ Hetalia Axis Powers 33v2 [Webcast].mkv"
    to
    "✘ Hetalia Axis Powers 33 [Webcast].mkv"
    automatically renames
    "✘ Hetalia Axis Powers 37 [Webcast].mkv"
    to
    "_HETA~34.MKV"


    Renaming
    "_HETA~34.MKV"
    to
    "✘ Hetalia Axis Powers 37 [Webcast].mkv"
    fails with error message
    "The name “✘ Hetalia Axis Powers 37 [Webcast].mkv” is already taken. Please choose a different name."


    Renaming
    "FULLM~20.MKV"
    to
    "Fullmetal Alchemist Brotherhood 20.mkv"
    fails with error message
    "The name “Fullmetal Alchemist Brotherhood 20.mkv” is already taken. Please choose a different name."
    Everything changed back to normal after renaming a few other files within the same folder


    Renaming
    "Oha Suta 20100331 [+, Koharu Kusumi].mp4"
    to
    "[+] Oha Suta 20100331 [Koharu Kusumi].mp4"
    automatically renames
    "Oha Suta 20090526 [Koharu Kusumi].mp4"
    to
    "OHASU~16.MP4"
    I undid that and added another file into the folder called "Ogawa Saki - Oha Star 100521.mp4" and renamed it to "✘ Oha Suta 20100521 [Saki Ogawa].mp4". Doing the same renaming thing above then worked fine.


    :confused:
    The weirdly named files work fine though.

    Is this happening on an HFS+ drive? Or a FAT formatted drive?

    FAT external drive (I am planning on formatting to HFS in the near future though in order to store 4GB+ files)

    Then that's your problem: it's an ancient format that only really supports short file names. There is a hack that MS implemented on top (and then everyone else who reads/writes FAT) to enable the illusion of long file names. For some reason you are seeing the real file names instead of the illusion.

    Only solution is to choose a different file format that truly supports long filenames without hackery... Which is HFS+ and many other Linux based file systems, but since you're on a Mac, HFS+ is the native way to go.
