"DisableNtfs8dot3" Does Not Correct the Error "The weblayout directory is on a filesystem with 8dot3 semantics" (Doc ID 1277159.1)

Last updated on FEBRUARY 02, 2018

Applies to:

Oracle WebCenter Content - Version and later
All Platforms


In every page of UCM 11g, the following message is displayed at the top:

The weblayout directory is on a filesystem with 8dot3 semantics. Legacy 16-bit 8dot3 filenames conflict with revision labels and will cause file loss. Disable 8dot3 semantics by running "Installer DisableNtfs8dot3" and then restarting Windows.

You are accessing the shared/remote filesystem using CIFS/Samba from a Unix/Linux server where Content Server is running, rather than using NFS or being directly attached to a SAN.


After running the UCM command "Installer DisableNtfs8dot3" and restarting Windows, the error persists.

After manually setting Windows registry to disable 8.3 naming support and restarting Windows, the error persists.
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation = 0x00000001)

When verifying if 8.3 naming support is actually disabled (see test below), the results show that the Windows registry change disables 8.3 naming support for the local disk C:\, but has no effect on the remote NAS/CIFS filesystem where the UCM weblayout directory exists.

The test (using no UCM code):

...against the local C drive:

C:\> echo "This is a test file" > 123456789.tmp
C:\> type 123456~1.TMP
C:\> The system cannot find the file specified.

Test result: 8.3 naming support is disabled for Windows and the C:\ drive.

...against the NAS/CIFS fileshare:

C:\> pushd \\server\weblayoutshare
Z:\> echo "This is a test file" > 123456789.tmp
Z:\> type 123456~1.TMP
Z:\> This is a test file

Test result: 8.3 naming is enabled on the NAS/CIFS remote file system.


You are accessing a remote/shared filesystem from where the Content Server is running.
