The copy of a file or folder in the target “C:\ProgramData\Symantec\Definitions\SymcData\virusdefs32” prompts the following error message.

Disk is full, but it shows at the same time 65 GB free space. The result is that the file cannot be moved from root c:\ as well as the Antivirus definitions.





“Windows System Resource Manager” caps the disk space preventing LiveUpdate to download the full set of definitions.




·         First solution:

Adjust the quota in “Windows System Resource Manager” to accommodate virus definitions in the folder:



·         Second solution:

Navigate in the Server Manager panel and disable/remove the “Windows System Resource Manager” role under file services if it is not necessary.
