0x0–0xFFFFFFFF ( files )
Determines how many files on each share can remain open in the redirector's cache after an application has closed them. If the number of open, cached files on a share exceeds the value of this entry, the system begins to close the cached files.
The Windows redirector keeps files open in the cache after an application has closed the file. This entry prevents cached files from occupying the limited number of places available for open files. By default, LAN Manager servers permit only 60 files from remote clients and 50 files from each client workstation to remain open.
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits it.
