Here is an article I wrote for or user group's (NAVAUS) newsletter last year,
it should answer your question.

Gem Alert, by Ray Wallace

As you probably all know GEM allows you to create folders (subdirectories) to
place some of your files in. This article will describe some of the folder and
file limitations inherent in GEM.

The top level (root) directory is limited to a maximum of 112 (256 for hard
disks) files (directories are counted as files here). This restriction exists
because the top level directory is created with a FIXED size when the disk is
formatted. (NOTE:Disk formatting programs can be written to change these
limits).

Subdirectories on the other hand can grow as need, so there is no limit
on the number of files that can exist in a subdirectory. Subdirectories
are really just specialized files, and just like other files can grow in size
so can subdirectories. One limitation to subdirectories is that they can
not shrink, in the sense that when you delete files (directory entries)
the subdirectory does not get smaller.

On top of all of this there is also a limit to the maximum number of files a
window will see. If you have more files in a directory than this window limit
then you will not be able to see (or access) all of the files in a particular
directory or subdirectory, regardless of how you scroll around with the scroll
bars.
