Finder/ Time Machine Password?

[RITZFit]

I was recently pulling some files off my time machine drive and pulled one I didn't need onto my desktop so I tried to delete it, but finder asked for my password before it would do anything. I thought this was weird since the folder wasn't locked and I don't have any type of encryption setup on my files. I guess my question is does time machine put its own special kind of read/write rules on files it saves? its never asked me for a password just to delete some stuff before 😕
thanks

It does, in order to prevent the user from accidentally deleting important backups.

even after I've already copied the file over to the desktop?

UNIX permissions stay with the files/folders - as long as they are on a drive that supports them. If you were to copy to a FAT32 drive, then back, the permissions would be gone.

Ok, I was just assuming the files would drop their time machine prefs after I copied them. I guess I was worried it was something else (malicious) try to get a hold of my p/w haha. Thanks I appreciate the info
