Hello,
Lately I've been getting error -42 (Too Many Files Open) with my Mac II.
For the light of me, I can't figure out why. I have a Macintosh II, 5MB Ram,
380 Meg HD with 7 partitions, Apple Color and Nutmeg 19 Monitor, and System
6.0.3. Can I increase the number of open file allowed?

Multifinder makes it easy to have lots more files open than you think you do. - Ken ------------------------------------------------------------------------------ Ken Hoover [ consp21@bingsuns.pod.binghamton.edu | consp21@bingvaxa.BITNET ] Resident computer jock and Mac hacker, SUNY-Binghamton Bio dept.

I recently encountered this problem too. Fortunately, there is an easy solution. You can change the number of allowable open files by modifying a parameter on your boot blocks. Most low-level disk editors will allow you to do this. I used the SUM editor, but I imagine that ones like FEdit and MacSnoop would work too.

If you're using the DeskTop manager, then there will be the Desktop DB and Desktop DF files instead of the original Desktop file, making it four files per mounted volume. Then if you use a program which keeps a document open for the duration you're working on it, such as a THINK C/Pascal project, or MPW. You'll run into the limit very quickly. As Byron points out, SuitCase II has a setting to allow more open files; nevertheless, you may wish to consider the root causes: lots of partitions, Desktop Manager, or applications which maintain open files, and take steps to correct them.

I have a Macintosh II, 5MB Ram, >380 Meg HD with 7 partitions, Apple Color and Nutmeg 19 Monitor, and System >6.0.3. Can I increase the number of open file allowed? The easiest way is to use Suitcase II. Open Suitcase, push the "Settings..." button, then the "`Power User' Settings..." button. You will see a number there. Mine is set at 40. You only need to do this once, so you could use someone else's Suitcase--while they are *not* using it, be legal please. Alternatively, I know that the old FEdit 3.21 has an "Edit Boot Blocks" item under the "File" menu, where you can change the maximum number of open files. It seems that the number is at offset 0x7b (3-bytes after the "e" at the end of "Clipboard File"), so if you are quite brave you could also use MacSnoop instead. For another choice, try Symantec Tools in the SUM package, it has an "Edit Boot Blocks" menu item too. (Come to think of it, isn't that where FEdit went, to MacZap then to SUM?) Warning: Suitcase is the only simple solution I know. All the others are dangerious programs which can alter *any* data on your disk, possibly blowing it away completely. Be sure you feel comfortable with these risks before preceeding. You might want to wait until people get a chance to flame any stupidities in this posting. -- Kent Borg "Wouldn't it be fun not to be famous? kent@lloyd.uucp Wouldn't it be fun not to be rich?" or -Cole Porter lyric (from Aladdin) ...!husc6!lloyd!kent
