There are two methods to delete documents from the document server.
To delete a document entry along with all its older and newer versions from the server, switch from to the detail view via the document name. Now click on the trashcan button
to go from the detail view into the delete mode. The system asks you a security question to make sure you really want to delete this document. If you are sure you want to delete the folder, confirm by clicking the Delete button. If you do not want to delete, you can leave the menu by clicking on Cancel. Of course, to delete a document you also have to have permission to do so.
To delete older file versions from the server, go to the detail view for a document via the document name and select the index card tab marked Versions from there. There you will see a table listing all the older and the current versions of the file. You can tell which version is the current version by looking in the Current column. There is a check box at the end of every version line. You have to put a checkmark in the box beside each version you want to delete from the server. Finally, click on the button Delete versions. The selected versions are now deleted from the server.
