I just ran into what seems to be a restriction on the number of directory entries allowed on a 3.5" 720k disk. I tried to put the 123rd file on the disk, and although there was enough storage space available, I kept getting file creation errors. I know there is an adjustable limit on RAMDISKs, but I'm not sure of 3.5" disks. I can't find anything on it in any of my DOS manuals. I am able to copy all 123 files to my 1.2M floppy though.

I don't think you can change the number of entries in the root directory, but a quick and dirty solution is to put all of the files in a subdirectory. The number of entries in a subdirectory is limited only by disk space available.

Each type of disk has a default for the number of allowed entries in the root directory, which is set on the disk at 'format' time. The simplest thing to do is to make a directory on the diskette, and put all of your files there. It should be able to hold as many as will fit on the disk. I think the limit for the 1.2/1.44 class is 212. 'fdformat.exe', from Germany (PD), allows different values for /. -- --- Clarence A Dold - dold@tsmiti.Convergent.COM (408) 434-5293 ...pyramid!ctnews!tsmiti!dold P.O.Box 6685, San Jose, CA 95150-6685 MS#10-007

There may be some formatting programs that allow you to specify the limit
of how many files you can put onto a given disk; if you can't find such a
program, however, you're stuck - IF YOU NEED YOUR FILES IN THE ROOT DIRECTORY,
that is.
The root directory is limited in size; however, subdirectories are not;
the only limit on the size of a subdirectory is the free space on your disk.
Therefore, if you run out of directory space while there's still free space
available, create a subdirectory (remember that this takes up a directory
entry in the root,so you'll have to remove one of the files first) and put
your files in the subdirectory.

There is a limit on how much can be in the ROOT directory of the disk. make a subdirectory, and copy all of the files there. That should solve your problem. Duane L.

The difference is that the root directory is a fixed area on the disk whereas sub-directories are files. regards, Larry -- Signed: Larry A.

All floppies (and hard disks) have a *fixed* number of sectors assigned to the root directory. As you say, this can be modified on a RAMdisk, but I don't know about floppies or hard disks. In any case, this restriction only applies to the *root* directory. You can get around it by creating a single directory on the floppy ("md a:\many") and putting your files into that (copy *.* a:\many).
