Environment

Client for Open Enterprise Server 2 SP4

Situation

Getting unexpected errors on Windows workstations, relating to path length when opening files located on Open Enterprise Server.

Resolution

Shorten the path length by renaming directories and/or files.

Cause

The maximum path length for Client for Open Enterprise Server is 260 characters, which is the same as Microsoft's MAX_PATH definition that many applications (such as Windows Explorer) are limited to.  The full path to the file or directory, minus any leading backslash characters, must be less than or equal to 260 characters. If not, the Client for OES file system driver returns a Windows-compatible error which the Windows file system drivers return in a "path too long" scenario.
