Hello,
Thank you for contacting us.
To revert the entire working copy back to a specific revision you could use the "Update to revision/depth" action from the Working Copy view contextual menu, by selecting the working copy root folder.
To select the desired revision, you should use "Other revision" option and the History button to see more information.
As depth you should use Recursive (infinity) to get all the folders and files at the specified revision.
Note that when using this action it will be better to not have any resource as outgoing. Those resources will remain in the working copy even after updating to a previous revision.
Another thing you could do is to completly delete the working copy and to do another checkout from the revision you want, but this will take a longer time than the first option.
Do not hesitate to contact us if you have any further questions.
Best regards,
Florin Avram
