Symantec Endpoint Protection Manager (SEPM) SymDelta_* folders and contents accumulate in C:\Documents and Settings\NetworkService\Local Settings\Temp or in C:\Users\semsrv\AppData\Local\Temp and are not removed after failed delta merge operations. These systems could potentially run out of disk space.


Not deleting delta merge files when delta merge is unsuccessful.


In Symantec Endpoint Protection Manager an option was added when to delete the SymDelta temp folders and contents by adding a value to the file. For information on how to obtain the latest build of Symantec Endpoint Protection, read TECH 103088: Download the latest version of Symantec Endpoint Protection

To implement the option after upgrading SEPM to or newer:

1. On the SEPM, open file from \Program Files (x86)\Symantec\Symantec Endpoint Protection Manager\tomcat\etc folder.
2. Add the following line:

3. Restart both Symantec Endpoint Protection Manager and Symantec Endpoint Protection Manager Webserver services.

Note: The SymDelta_* temp folders and contents will be deleted based on the value used (days= can be set to: 0, 1, or 3)

(Deletes all the SymDelta_* folders)
(Deletes a day old SymDelta_* folders)
(Deletes 3 days older SymDelta_* folders)
