Does anyone know how many entries are allowed in a (sub)directory ?? -- uucp: mcvax!eurifb!benno | Ben J. Noordzij earn: benno@hroeur1 | EUR/bedrijfskunde, Burg.Oudlaan 50, phone: +31 10 4081931 | 3062 PA Rotterdam, Netherlands

The number of entries allowed in the root directory is limited. It is variable
across different types of disks; its value is given by the number of bytes
in a disk allocation unit, divided by 32 (the size of a directory entry).
The number of entries allowed in a subdirectory is limited only by disk space;
subdirectories may span more than one allocation unit.

Ya. As many as you have disk space for.
A sub-directory is like a file, it can keep expanding until you run
out of disk space.

I'm NOT sure that the same root directory limitation applies to high-density disks or hard disks, but I do believe that subdirectories are dynamic, and limited only by the disk space. =#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=#=# Dick Gardner Eastman Kodak Co.

There is no limit on the size of a DOS subdirectory. Of course the larger the directory the slower accesses will be due to searching time. There IS a limit on the root directory, that is fixed at format time and is dependent on cluster size and size of the DOS partition. -- Timothy Lange / PC Learning Resource Center Purdue University Computing Center / West Lafayette, IN 47907 317-494-1787 / tim@j.cc.purdue.edu

In the root directory, the maximum depends on the size of the disk. I can't remember exactly how it's determined, but it's usually plenty of entries for the disk size. Subdirectories are not supposed to have a maximum number of entries. I suspect that they do have a maximum, but it's probably a maximum related to the DOS maximum file size, ie 32mb. This would be a large number of files, so for all practical purposes, it's unlimited. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Jim Frost * The Madd Hacker | UUCP: ..!harvard!bu-cs!bucsb!madd H H | ARPA: madd@bucsb.bu.edu H-C-C-OH <- heehee +---------+---------------------------------- H H | "We are strangers in a world we never made"

There was a question here about the number of entries in a DOS directory. The max allowed is 128 entries in the root, but the subdir's can be unlimited.
