By default, full file asset deployments check the timestamp, file size, and checksum of a file on the agent before pushing a new version of the file from the asset management server. If the files match, the new file is not sent. Note that the timestamp check is not for the exact timestamp but for a more recent file on the server.
Occasionally, you might want to disable checksum verification in order to purge all file assets from a target site. You can disable checksum verification by setting the following property in the /atg/deployment/file/DeploymentConfiguration component on the asset management server:
noVerificationByChecksum=true
Note: This property must be set to true in order to configure Background Deletion of File System Assets.
