Importing files to WMP from all sources on my computer

Is there any fast way to delete multiple copies of my music files From
WMP11.When I imported my albums they have appeared up to as many as 6 times
in WMP library.To delete them individually will take hours

 

To begin with I wouldn't trust the library display in the v11 beta as
it's buggy.

Roll back to v10 and see if the problem remains.

 

Before deleteing anything from the WMP 11 library in order to resolve flaky
information, check that the option under Tools... Options... Library...
"Delete files from computer when deleted from Library" is cleared. This
option is set by default during installation which I feel is a *bad idea*
particularly as, unlike WMP10, it no longer warns you the first time you go
to delete anything.

Multiple albums in the library may be a sign of incomplete media
information. If you look closely you will probably find that each track is
only recorded once, but the album is being treated as if it were several
albums. This can usually be fixed by updating the tags. Select a view in
which you can see all of the tracks at once - e.g. Artist view - then select
all the tracks from the Album, (use shift & ctrl to help select ranges or
individual tracks). Right-click & select Advanced Tag Editor, then edit the
Artist, Album Title & Album Artist fields, even if you just replace the field
with the same information. If you refresh the view WMP should now treat these
files as a single album.

The Tag Editor doesn't expose the "Year" field, which should also be the
same for each if WMP is to treat it as a single album. This, however, can be
edited in Expanded Tile or Details views. A long standing bug means that in
some regions you have to add one to the year to get what you want - e.g. type
in 2001 and WMP will record 2000.

 

I'm quite familiar with all these, having documented them all here over
the last few years:

The errors in v11 beta go above and beyond these issues that have been
around since v9.
