The recycle bin is a temporary storage location for projects that have been deleted. It gives you a chance to restore the deleted project to its original location, if needed. Projects in the recycle bin are stored until you either empty the recycle bin or delete each individual project from the recycle bin.
Whenever you delete a project from a database, a confirmation window like the one shown next will appear.
If you want to move the project to the recycle bin, make sure the Send project to recycle bin check box is selected. If you want to immediately and permanently delete the project, clear the check box. Remember that once you empty or delete a particular project from the recycle bin, there will be no way to get it back unless you have previously created a backup or restore point.
In a secure database, the ability to restore and delete projects from the recycle bin is available only if the user a) is the project owner, b) has the "Delete project" permission, or c) has the applicable "manage all projects" permissions).
To restore a project from the recycle bin, select it and choose Project > Management > Recycle Bin > Restore Project.
To permanently delete a project in the recycle bin (no way to undo unless you have a backup or restore point), select it in the recycle bin and choose Project > Management > Recycle Bin > Delete Project.
To permanently delete all projects currently in the recycle bin (no way to undo unless you have a backup or restore point), select the Recycle Bin heading in the project list and choose Project > Management > Recycle Bin > Empty Recycle Bin.
