If you've accidentally or intentionally deleted a file from a case and would like to recover that file, you can do so for 90 days. After 90 days, the files are permanently deleted and are unrecoverable.
Recovering a Deleted File
To recover a deleted file upload, click the Files tab on the case and then filter by Deleted Files.
Note: If the file is located inside a folder, you should first navigate to the folder the file was in before filtering the list.
After locating the file(s) to recover, check the box next to each file and click the Undelete button above to recover the file.
