	Each mounted volume carries an overhead of three open files:
catalog and extents B-Tree files, and the DeskTop file. 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.
