Extract without Getting - following an "Offline" job

Hello
Following a server problem,  I removed the read-only on some files to work on them. The PDM server is available again, so I want to extract the files without overwriting my local version, and then archive my version. 
How to proceed?
Thank you for your insights!!

Kind regards 

Well, I'll use this: 

- Workspace backup
- In the copy, search for files
> Attribute = A (writeable)
> Modified after the... (date the server dropped)
- File by file: 
> Searching for the file in the PDM Explorer
> Extract the file
> Overwrite the file in the PDM folder from the Backup
> Open the copied file in the PDM
> Archive. 

Then: 
- Search for extracted files
- Remove read-only (in PDM)
- Open, archive:
This last step because of a few tests and failures...

Enjoy!
