If you want to use library options then use the "Location" node, instead of "My computer".[/quote]

As I explained in my previous post, I only drilled down into my Computer *after* the problem occurred. I have been using MM since the early days of MM2, I do know my way around the interface. I just hadn't used the My computer root in so long I forgot delete worked differently there.

The problem is solved now, but here's what happened.

I dont do manual scans, I just rely on File Monitor. After I installed MM4 and ran it the first time, no problem. The second time I started it up though, I got a "1100 new tracks found," and that's when the problem started.

I'd gone to Tools -> Library, and clicked the File Monitor tab, and checked just the subfolders I wanted were checked. All was as it should be.
Then i went to File -> Rescan Tracks, and made sure just the subfolders I wanted were checked. Ditto (naturally) and I did a rescan. The tracks were still there.
(That's when i went to my computer to delete them - i should have created a playlist with the path variable.)

Then i posted here, and slept on it. Now, after your post (and after a reboot), I did another rescan and they have vanished. Why that would make a difference I don't know. Oh well, sorted now.

[quote="MeMeMe"]I just upgraded to MM4, and found MM scanned my entire My Music folder, despite the fact i had only selected Music/Songs.
I tried to delete all the tracks from my Music/Temp folder: in the past I would have the option of deleting just from the librarey, nut not the hard drive. When i select delete now, it just offers "are you sure you want to delete these tracks" and I dont know if its going to wipe them from my hard drive.[/quote]
This means you're looking at a "My computer" node, not a library node. So you are only offered to delete the files from the computer since you're not looking at your library.

I have a folder monitor set on My Music/Songs, and NOT on My Music (or My Music/Temp).
How can i clean up my library: get these files out of the library without deleting them from the hard drive, and ensure they wont be scanned again?
