Already deleted files are not restored when you abort the process which is deleting files.

Now, if you were actually running rm -i or similar, which makes rm prompt before deleting, then only the files you told rm that you wanted to delete are actually deleted. But those are still gone. Not using a switch like -i simply avoids the prompt.

Depending on which file system you are using there may be undelete tools available, but if you are missing anything which you need, the easiest solution is probably to restore from backup.

Since this isn't your system and you don't have root access, undeletes become even harder to perform; you'd need access to the raw physical device and you'd have to prevent any further disk writes to the partition(s) in question to minimize the risk that the data blocks get overwritten, and both of those are difficult without root access.

Some specialized file systems allow true transactional-style operations or have the ability to go back to a given past point in time (NILFS being one example) but those are practically unheard of except in specialty applications, which I doubt a 2-3 years old Fedora install will be.
