If you check out a document and make changes but decide that you do not want to commit your changes to the server, you can cancel the check out and revert to the server version of the document. This action discards any changes you made to the document after it was originally checked out.
From the Library or Outline Editor, select one or more documents or folders containing the documents for which you want to cancel a check out. These documents can only be documents that are checked out to you.
You can select multiple documents using the standard Windows selection keys (CTRL+click and SHIFT+click).
On the Document menu, choose Cancel Check Out.
The Related Documents dialog box appears when you perform an action on any document that has links to other documents. You can choose to process only the document(s) you selected or to process your selection and all of the related documents.
Click the View related documents link to display a list of the related documents if you are not sure whether you want to include related documents.
After you have made your selection, click OK.
You might also receive a message if some documents could not be processed because of other constraints. You can click OK to close the message box or click the View activity log link to view the results of the action.
