Use the Local Data Manager (Teamwork >Project > Local Data Manager) to delete your local copies of Teamwork projects and libraries. This means, of course, that you will lose any changes that you have not yet sent to the server.
Deleting your local data is equivalent to leaving the project, except that your reservations will remain. Should you wish to work in the project again, you must again join the project, thereby downloading a local copy of the project as well as its libraries.
1.Go to Teamwork > Project > Local Data Manager.
2.From the list, select the Project or Library you wish to delete.
3.Click Delete at the bottom of the dialog box.
4.The selected project or library copy is deleted from your Local Data Folder.
Note: If you choose to delete the local data of a project from a BIMcloud/BIM Server that is online, ArchiCAD will recommend that you leave the project instead of just deleting the local copy, because leaving the project will also release your reservations.
In any case, if you should prefer to delete the local copy, you should also release your reservations.
