files are untouchable

[pintree3]

I have some mp3 files which can not be moved, copied, deleted, or dragged to
the or anything else.somewhere including all media players I have.
If I R-click on any one file instead of getting the usual drop down menu I
only get a few choices. Most important choice missing is "properties"
I do get the choice if I choose all of the files though. So I chose all of
the files and then go to properties, it will show as checked "Read only" and
"Hidden" and if I go to the advanced button it will show all choices as
checked. If I uncheck them and then click on Apply and the OK nothing
happens. If I then R-click again the above mentioned are all checked again.

This has happened before. And the one thing I remember in all cases is that
I checked on a group (or all) files and began the process of moving them. I
feel that while doing so the mouse did something wrong--like accidentally
double-clicked or released one of the files or something. In any case. Some
of the files were moved and others not. The rest became untouchable. I tried
a software program named "unlocker" and though this has worked wonderfully in
all instances of a locked file this is not the case here.
It's as if these files don't exist, asif the are invisible in every way
except to my eyes.

Of possible interest: I downloaded a software program called 'FileBoss' in
the hope it would solve the problem--I didn't BUT something interesting was
revealed. Though all othe MP3 files showed their proper icon, these files did
not. They had the usual icon of an 'unknown' file.

Any suggestion as to how I can delete these files?

I have encountered some MP3 files that for some reason had a DRM
security applied onto the file. This DRM security was controlling how
to use these file.
