Yes. Moreover, "WinZip", the most popular archive-handler, doesn't grok bzip2. > > (6) You are keeping open handles for all files of a given size -- have > > you actually considered the possibility of an exception like this: > > IOError: [Errno 24] Too many open files: 'foo509' > > (6) Not much I can do about this.

Test, like I did, to see how many open handles you can get away with. I was not joking, 20 was the max on MS-DOS at one stage and I vaguely recall: (a) some low limits on various flavours of *x (b) the "ulimit" command can be used to vary the per-process limit but (c) there is a system-wide limit also. You should consider a fall-back method to be used in this case and in the case of too many files for your 1Mb (default) buffer pool. BTW 1Mb seems tiny; desktop PCs come with 512MB standard these days, and Bill does leave a bit more than 1MB available for applications. > > And what is "chown" -- any relation of Perl's "chomp"? > > chown is a Unix command to change the owner or the group of a file.

It detected some highly plausible duplicates, which I haven't verified yet. Cheers, John -- http://mail.python.org/mailman/listinfo/python-list
