One of our mac users has been plagued with this bizarre problem. She has an SE, a 40 meg FX drive and tape backup. She is running a number of different inits (about eight total) and system 6. While backing up her hard disk she noticed a folder which contains five other folders. She can open the first folder but cannot open the other folders (gets this strange in use message). She also cannot throw the folders out (she gets a Folder not Empty message). She can rename the folders and move them around--but they refuse to die. If she copies the folders to a floppy, she can see that there is nothing in the folders and can throw them out. Further, if she boots off a floppy and then tries to throw out the folders, she still cannot get rid of them. Any advice or help? -- ************************************************************************ Todd Heatherton Department of Psychology University of Toronto Phone: 416-978-6387 (office) Email: heath@gpu.utcs.utoronto.ca 416-482-4847 (home) or heath@psych.utoronto.ca ************************************************************************

HMMM.... If there were invisible applications/documents in the folders you would not be able to see them if you looked, and they would not be copied in a finder copy. Your friend might want to use the MacTools utility that comes with Copy II Mac. This would show any invisible files and allow you do delete them. Worth a try. You did not mention if you had AntiToxin INIT. IF you have that INIT AND if you had a virus attached to the folders then you would get a App missing or in use message. Only problem is I do not think a virus can attach itself to a folder. Try Copy II Mac. TeriAnn

Sounds like a case of your directory sturcture being corrupted. The Folders that Won't Die have a valence greater than zero even though there aren't any files in them. There is a way to fix this, and I don't know how to do it offhand. It would require some very careful perusal of Inside Mac Vol. 4 to figure out how to fix it. I'd suggest that you back things up file-by-file and reformat the disk. That's not a bad idea every once in a while anyway. --- Alexis Rosen alexis@ccnysci.{uucp,bitnet} alexis@rascal.ics.utexas.edu (last resort)

That's >not a bad idea every once in a while anyway. There was a discussion of this problem on FidoNet's EchoMac a few months ago. I saved a couple of messages from it and put them to use when I ran into an undeletable folder. I followed the directions and after a bit of experimenting I succeeded in dragging the problematic folder into the trash and getting rid of it. As the messages note, the directory information for a folder can seemingly get munged on occasion, making the Mac OS think that there are files in the folder even when it is empty. Alexis notes the the valence for the folders is greater than zero but a negative valence can also apparently cause the problem. I mailed this info to the person who posted the original article, and am supplying it here as this seems to be an occasional problem and the methods described below not only work but are much less troublesome than reformatting and recreating your whole hard disk. Please note I am _not_ supporting the methods described below as a universal cure for this problem... I certainly have not done any testing other than to apply the methods (and quite successfully) to my "Folder From Hell" experience. Jim From: Chuck Shotton To: Andy Shaw Msg #383, 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 Msg #445, 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.UUCP (James Macak) or lakesys!macak@csd1.milw.wisc.edu

That's >not a bad idea every once in a while anyway. Actually, in the times I have encountered this problem, the problem was a valence of less than zero (typically -1). Apparently a negative valence is automatically displayed as "0 items" in the finder window, but does show up in an attempt to trash the folder. I have forced the folders to be trash- able by putting a dummy file into them, thus making the screwed up valence 1. Note though, that while the folder may go away, the directory structure is probably still screwed (I have had Disk First Aid say "unable to verify disk" after such operations) and it may still be best to back-up and reformat as Alexis reccomends.
