If enabling the Purge FileStore robot job on a database that contains a large number of files, many of which are deleted and therefore to be purged:

• You may see timeouts in the robot log
• Manually running the job in App Manager may fail with a timeout error

This is because although the job deletes files in batches, where numbers are large processing the initial batches can exceed the amount of time the service is prepared to wait for completion.

The workaround is to perform an initial purge via script:

• ensure nobody is using the system
• backup the database and verify
• run the attached SQL Server script to perform the initial purge

The robot job can then be enabled.
