Qbox Recovery folder is created in the same directory path as the Qbox folder. If you worked on a file without locking it, and Qbox needs to sync changes made by another user, it will first make a copy of your file, and then sync the file from the other user. If you prefer to use your version of the file instead of the version synced by the other user, you can recover it from the Qbox Recovery folder. Qbox maintains up to two copies of the recovered files named copy 1 (most recent) and copy 2, in the recovery folder. You can rename the file back to the original, and copy/paste the file into the Qbox Explorer to replace it with your version.
