File Locking in AceProject: Document Control & Check In/Check Out
File Locking
Lock a document to leave the original copy intact. Prevent other users from editing or deleting a specific document.
Feature Description
The file locking feature enables users to simulate a "check in/check out" system for project and task documents. Locking a file makes it "read-only". As a result, locked documents are protected against editing and deletion. This is useful to prevent anyone from deleting, for instance, document templates or master copies.
Users can download a copy of a locked file, but cannot overwrite it. Should a user need to re-upload a locked file, they have to create a new version, which will consequently create another file and preserve the original (the locked one).
