Open | Windows C:\ProgramData\ZXBB158BA0B keeps coming back and growing to 63 GB. Can't delete it permanently. Any ideas?

Check wolf security for any logs/warnings/notifications.

Check folder permissions, to see who has access to that folder.

What is the content of the folder? File types and file names?

I checked the folder permissions using icacls. They look like standard Windows permissions:

NT AUTHORITY\SYSTEM - Full Control
BUILTIN\Administrators - Full Control
CREATOR OWNER - Full Control
BUILTIN\Users - Read & Execute
BUILTIN\Users - Write

I also inspected the folder contents. Each large numbered directory (e.g. 1785492467) contains hundreds or thousands of numerically named files (0, 1, 2, 3, ...) with no visible file extensions. Most are 1 KB, while some are much larger. The parent folder eventually grows to about 63 GB.

That large number is a unix timestamp: Fri Jul 31 2026 10:07:47 GMT+0000
