When using jiffydos or a wedge the amount of files in a SD card
directory doesn't seem to matter since they are just listed and not
read into memory to list. However when using a regular directory
command or sd2brwse to read directories what is the max amount of
files per directory. I seem to be getting lockups and randomness when
reading large directories. Thanks for any help.

The 1581 supported 288 directory entries, so any program that works
with a 1581 ought to support at least 288 directory entries.

A standard 1541 directory is limited to 144 entries, including any
dividers/directory art.

A handy trick is the limited directory. For example:

LOAD"$:*=P",8 will list only PRG files
LOAD"$:T*",8 will list only files starting with the letter T
LOAD"$:C?T",8 will list only files that match the pattern, with the
question mark acting as a wildcard.

This should work with wedge and JiffyDOS commands as well.

There are however instances where the directory has been tampered with
to show nothing, or for it to recursively display itself hence giving
the appearance of never end. Both can crash directory viewers without
the traps to catch these instances.
