    I was playing with Astro and noticed that LOST.DIR uses the most space on my SD card (I haven't downloaded songs yet), 35 MBytes. Anyone know what that is?

    Also, the Process Manager seems pretty cool. Anyone used that over Task Killer? I guess if Process Manager works I don't need task killer.

    Thanks.

    I believe the Lost.dir is used for compatibility with the Mac OS, so it would only be used when connecting to a Mac.

    LOST.DIR is something mac disk repair looks for and will ask about as part of it's repair process. If it's related at all to the standard lost+found, then it's a special file that holds all the corrupted or orphaned files found during a file system check.

    So Droids is correct...

    For my experience the LOST.DIR is like the recycle bin from windows. Android is a linux derivate so if you delete a file via Windows PC, and forgot to unmount the device, where such files get deleeted, the LOST.DIR keeps em for recovery

    Right now it doesn't take up much space. However, if it grows to 100 MB+ I would definitely want to delete it.

    Speaking of Directories on the SD card, does anyone know what the "agilefusion" directory is for?

    It has a subfolder called "Thumbs" and inside that a ton of "cache" files.

    AND the reason I ask is I have noticed a lot of apps leave directories behind and I like to clean them out when no longer using the uninstalled app.

    Ok, that's just not true. Please don't give false information. 1 minute ago, I emptied my LOST.DIR folder out, and it was approaching 3 Gigs.

    I only use a Mac, and I connect it all the time to the Droid.

    The guy simply asked a question, and he's gotten a bunch of grief over "if" it's ok to delete the contents or not. The quick answer is yes, as long as you don't wish to recover any of the files that you have transferred during your connection to the Mac.

    Sorry the community had to go Freudian on you to answer a simple question.

    Merry Christmas! Hope you and yours have a wonderful holiday season.

    It's strange, I have this same folder on my SD, but I've never connected it to a mac. Could it be this folder also houses partial files if I were to accidentally unplug the USB while files were transferring? I have done that before.

    Lol you gotta love when people answer questions with questions and other miscellaneous commentary instead of answering a question. I've actually been curious about this directory for some time now, just not overly curious. I completely agree with the "get rid of it because it's there" mentality; if you don't use it, and it isn't essential, then that means it serves no purpose and is dead weight, only a die hard hoarder would oppose such a view.

    So given I've never connected the Droid to a Mac, but have definitely had various screw ups during the transfer/mount/dismount process, I assume this directory is simply for ANY deleted or 'lost' file for recovery purposes. Rather than delete the directory I'll simply delete what's in it; only 20+MB but space is space. Another old thread dug up from the grave for those who were curious. ;)

    Googled this question and this thread was at top. And I agree with you 100%, thanks for the straightforward answer.

    Why wouldn't you want to delete the contents of this folder? Why would I want to keep something I obviously don't need? I'm really surprised it was a Mod who was questioning the question.
