I am yet to see an easy "fix" for this. (Hint, anyone want to tackle this with a quick and dirty application?) Following are "reprints" of some instructions that I came across on FidoNet's EchoMac area some time ago. I followed the instructions and indeed was able to delete the "Folder from Hell" that my disk had once upon a time. Beware that you may damage your disk directory if you muck up this "fix," so best to back-up first!!! (I take no responsibility for what you do based on this message... you have been warned!) Anyway, here's the info... USE AT YOUR OWN RISK. Jim macak@lakesys.lakesys.com (James Macak) ----- From: Chuck Shotton To: Andy Shaw 31-Jan-89 08:31am Subject: Re: RE:help! Undeletable Fold I posted a message about getting rid of undeletable folders a few days ago, but I'll repeat the main points. The undeletable folders usually pop up when running Multifinder, but there is a definite bug somewhere in the bowels of Finder itself that causes folders to end up with a file count that is non-zero (positive or negative) when the folder is really empty. The easy way out of this problem is to take a tool like FEdit or MacSnoop and set the count in the directory to zero. If you're not familiar with the directory structure, play around with a floppy first by making a folder or two, putting a known number of files in each one, and then searching the disk for these values. The easiest way to find the correct area on the disk is to search for the folder name first, then look for the file count number. Once you get this technique down on a floppy, just do the same thing for your undeletable folder on your hard disk. You'll know the proper offset from the name field, so it shouldn't be hard to find the right bytes. Remember what the original byte(s) were that you changed, in case you screw up. Besides, you probably won't be any worse off after the edit than before, given that the folder is trashed already. I've used this technique successfully on 4 "empty" folders which contained 3, -1, -6, and -2 files respectively. After setting the file count to zero, all were deletable. One word of caution. Make ABSOLUTELY sure that there are no hidden (off the screen) or invisible files in the folder before you set the count to zero. Chuck --- * Origin: Brain In A Pan, Houston TX, (713) 480-7422. Mac Developers Here! (Opus 1:106/260) From: Steve Zopfi To: Andy Shaw 31-Jan-89 03:14pm Subject: RE:help! Undeletable Fold I finally found out how to destroy it. First rename the folder something like FolderFromHell to distinguish it from the rest of your desktop. Open up the Volume using MacSnoop. Search the disk for FolderFromHell (there may be multiple occourances). In the hex section of the window you will see a string that looks something like this: 0000 0100 XXXX where XXXX contains the number of files in the folder in Hex. Change XXXX to 0000. Make sure you do this to all occurances of FolderFromHell. Write the Block to the disk. Go back to the desktop and trash the folder and empty. It should go away. I am not sure what caused the problem originally. I believe it was linked to the power going out during a download from a BBS. Yours may have happened the same during a Disk I/O in Sum or whatever if the power Glitched. Good luck and let me know if it works. --- Tabby/Mansion 1.8 * Origin: Sea/Mac *Mansion/Tabby* (206-725-6629) HST (1:343/31) ----- -- macak@lakesys.lakesys.com (James Macak) "I'm curious, Doctor, why is it << All my own opinions. >> called 'M-5' and not 'M-1'?"
