i've not seen this posted before so i thought that i might pass it along, there is a limit of 256 to the number of files that you can have in one window/folder, if you try to add the 257th you get a message about the file being read-only or some such nonsence and the copy operation fails -- ---- These are days for the locust to eat - Winston Churchill Name: James M.

Newsgroups: comp.sys.atari.st Subject: Summary: Expires: Sender: Reply-To: grunau@husc2.UUCP (justin grunau) Followup-To: Distribution: Memtest and Chkdsk queries Organization: Harvard University Science Center Keywords: Hi -- does anybody out there have any memory-testing routines out there, uuencoded, ARC-ed is fine, that they can send to me via e-mail or post to the net? (the best way to reach me is on host husc4, not husc2) Also, some sort of chkdsk (disk-checking routine) for a hard disk? I have COMPUTE!'s "STSHELL.PRG" from one of their disk-magazines -- it is a very simple, mostly not very useful, slightly-CSH-like CLI. It has a command called "mf" for "memory free", I guess, only what it tells me is that I have 786442 bytes available. Since I should have a little closer to a meg than that (the program itself is only 23447 bytes long, and the desk acc- essories certainly don't take up that much slack), so either there is something wrong with the "mf" program, or there is some memory in my machine that is not working. Does anybody have any advice on testing this out (short of finding a good memory-testing routine)? I do not yet have any compilers. thanks, JJMG

----------------- There is still another limitation on number of files... Namely, on a floppy disk, the root directory cannot have more than 112 files in it... This is calculated as follows: by default 7 sectors are allocated for root directory info on a floppy disk, where a sector is 512 bytes... each directory entry takes up 32 bytes. 7 * 512 / 32 = 112 files. I haven't actually tested this limit out in practice, but I think my arithmetic is correct. Of course, more files could be put in folders and the like...

The Desktop can't handle more than 400 (or so) files in ALL open windows put together. I'm not sure about imagen!turner's 256-file limit in one window, but I am sure that the root directory of each device is of limited size, and subdirectories are NOT limited. If there is such a limit, it is imposed by the desktop, not the OS, so if you abandon the desktop (in favor of a CLI-type shell) you will not find most of these limits. The 40-folder limit stands. The rumors that it's gone are greatly exaggerated. You can sometimes create more than that, but this limit is like a loaded gun: just point and click. /----------------------------------------------\ | Opinions expressed above do not necessarily | -- Allan Pratt, Atari Corp. | reflect those of Atari Corp. or anyone else. | ...lll-lcc!atari!apratt \----------------------------------------------/
