Maximum number of folders

[Rancher]

Does anyone know what is the maximum number of folders you can have in an NTFS, Server 2003 share? Thanks!

AFAIK - there is no practical limit for number of folders

Depending on the ratio of (millions ?) of files and folders to disk size - be aware of how NTFS reserves space for the Master File Table: http://support.microsoft.com/kb/174619

Also the practical effects of having max (or millions) of files on a given volume may affect performance and backup/restore times. Some of the checks when runing Chkdsk use time proportional to the number of files and folders.

NTFS by default always generates short filenames and keeps track of last update times - both can be disabled to gain performance.
