The Symantec Endpoint Protection (SEP) client generates many folders in the C:\ProgramData\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\ErrMgmt\Queue\Incoming.
These files and folders consume a large amount of disk space.
The application or process crashes may not be related to SEP.
When SEP is installed, SymQual and Windows Error Reporting debug settings are added to the Windows registry. When an application or process crashes, files and folders are generated, and data is sent to Symantec. If the SEP client is unable to transmit this data to Symantec, these files and folders remain on disk and consume disk space.
Investigate other applications or processes that crash and implement a fix as necessary. This step stops any additional creation of files and folders.
