Use MDO File Locking when you are sharing an Autodesk AutoCAD file with a colleague. A file lock is used to prevent two people from opening and updating the same DWG file at the same time, resulting in one person’s updates wiping out the other’s.

File Locking is available in the My Docs Online Desktop App, which works with all versions of Windows and Mac OS X.

File Locking is supported for all versions of AutoCAD and Autodesk product suites.
