I believe it is more of a problem for floppy drives, but can be for hard drives also. According to my DOS manual (Dell 3.30), you can have up to 112 files in the root directory of a 5-1/4 DSDD disk or 224 entries for a 3-1/2 HD (1.44M) disk. It doesn't say how many for a hard drive. I'm pretty sure that this is because of how the disk is formatted. The root directory is in a fixed location on the disk, and its size is determined when you format. Subdirectories, on the other hand, are treated like files and can be anywhere; in particular, they can be extended, so that you aren't limited on how many files you can have in them. >-Joe -- Jim Marks | Georgia Tech Research Institute Compuserve: 72310,2410 | Concepts Analysis Laboratory Internet: jm21@prism.gatech.edu -or- jmarks@gtri01.gatech.edu
