## How to Overwrite a File in a Vault from a specified Directory

| ### What to do:
| In order to be able to modify a file, the file must be retrieved from the vault (Check Out). Files that have been checked out cannot be modified by other users until they are checked back into the system. To work through this example, you must first complete the example Retrieve a File from a Vault - Check Out.
| Select Start > Documents > All Documents The Document mask is opened.
| Select the document DOC-1120 Ball Pen Description.
| Select the Files tab.
| Select the file to be checked in.
| This operation can be performed with any available file.
| Select Overwrite > From selection directory from the context menu. The FMS-File Requester is opened.
| Select a file from your file system.
| Agile e6 will now copy the file into the vault overwriting the current file with the new file.
| If you have selected a different file name (or Original Disk+Path), the corresponding fields will be updated automatically.
| Agile e6 does not cancel your reservations. If you wish to cancel a reservation you need to do this in the Document Management.
