You can automate the cleanup of your workspace files using the auto-deletion feature. dotMemory will automatically delete workspace files that were not opened* a certain amount of days. If you want to prevent a workspace from auto-deletion, you can pin it in the list of workspaces.
To enable workspace auto-deletion
On Home page, choose the Preferences tab.
In the Save Workspaces section, in Auto-delete workspaces that were not opened in last [ ] days, specify how many days workspaces must not be opened to qualify for auto-deletion.
Click Save Changes.
To prevent a particular workspace from auto-deletion
On the Home page, on the left panel, choose Recent | Workspaces.
In the list of workspaces, click the pin button against the workspace you want to prevent from auto-deletion. You can "unpin" the workspace back at any time.
