Is there a way to prevent accidental delete in OSX? I asked this because I have a 5TB drive of stored media files. I have to constantly manipulate files in the drive (copy, paste, delete, move files around etc). And I fear that one of these days I'm going to accidentally delete the root folder of 5TB of data. I can't use time machine or backup solutions, because it's already on a raid drive so I had to purchase 10TB worth of drives. I can't afford to buy another 5TB of drives just for backup. I must also add that I access the drive over the network (NAS) so even though it's done through finder, it's not the local file system which doesn't allow for undo. Any ideas? Thank you.
