TempDownload” which is where updates are saved until they have been successfully retrieved from the Internet and moved to the permanent storage location (“Manage Updates”). This location can be set in the LUA server’s preferences. It does not need to be on the same default C drive. It is normal for this folder to be empty after the materials have been downloaded successfully and transferred to their “permanent” location.
(One technical note: despite its name, this folder is used as temporary space during both Download and Distribution tasks- not just downloads. If a download task and separate distribution task are running at the same time, TempDownload will temporarily grow quite large.)

Symantec Endpoint Protection Manager directories contain many .TMP folders consuming large amounts of disk space

From the screen shot it looks like you have SEPM and Luadmin on the same server, Symantec does not recommened these two on the same server.

LiveUpdate Administrator 2.x and Symantec Endpoint Protection Manager on the same computer

Screen 1: TempDownload is where Luadmin stores all the downloaded contents. wrt to Luadmin I dont suggest to delete anything...from here

From Screen shot 2.

Content\Alphanueric folders are where the Virus Definitions for SEP 12.1 32bit and 64bit clients are stored

Each of the subfolders in these folders will be one specific virus definition revision. As for the sizing for each revision SEPM stores file (around 200-250MB) and extracted "Full" folder (around 450MB) - altogether one revision takes then around 650-700MB + additional space if there are any delta definitions files inside (.dax) - this needs to be mupltiplied by factor of 2x - as per 32bit and 64bit definitions stored.

As you are keeping 20 revisions - 1.3/1.4GB x 20 = the content folders for the AV defs only may increase in size up to 26 GB / 28 GB and this is expected.

if you want to minimize you can set the number of content revisions under SEPM- Admin -Severs tab.

Make it 3

As I've mentioned on your other two threads (and as Rafeeq has kindly repeated), it is not recommended to have the SEPM and LUA on the same box.  Not only are they known to have compatibility issues, you will also essentially be storing the same defs up to 5 times.

Link to my other post below (which by the way also includes lnks to articles that help free up disk space):
