Purging files from your recent documents folder
Whenever you open a file from iManage Work using the iManage Work Desktop for Windows application, a copy of the file is downloaded to the %AppData%\Roaming\iManage\Work\Recent folder. Unless deleted manually, the files remained in the folder. To prevent files from accumulating and unnecessarily increasing hard disk space usage and to prevent the risk of accidentally deleting files that were taken offline, iManage has introduced the Purge feature that automatically removes files that have not been modified within a configurable number of days (default is 30, minimum is 1) from the Recent folder.
The iwPurgeRecentAgeThreshold option enables you to configure the purge feature. For more information, refer to the imWorkOption.xml section in iManage Work Desktop for Windows Customization Guide.
