You need to have permissions in order to delete a document from the library. Normally you need to be an Administrator.
1. Navigate to the Library.
2. Change the view from All Documents to either Folder View or Int Admin view.
3. Select the file you wish to delete.
4. Click delete on the ribbon.
5. If you don’t see the Delete button, then you don’t have permission to delete that file.
Note: If your library has PDF’s – You will also need to go to the associated PDF folder and delete its corresponding PDF file.
When you delete a document, any outstanding read tasks for users will be auto closed. If you restore a document from the recycle bin, any previous tasks will NOT be reopened. You will need to publish the document to create new tasks.
