Question Running second session of Microsoft Media Player?

[Lautermilch]

I have a huge MP3 collection that contains a lot of files I don't want. I have found that Windows Media Player has been best for my tasks of removing duplicates and copying the files I want into a smaller collection. I have tried some of the other programs but it always come back to Media Player works best for my tasks.

I have a new Dell Windows 11 machine and was looking for the easiest way to run a second copy of Windows Media Player so that it could be doing the larger folder that has files for locating and cleaning while my main Windows 11 machine would have the smaller database of just the folder of the 'cleaned' files.

Most of these programs will use a programming method to prevent a second copy of the program from running. You would not want the second copy to modify a database while the first copy is using it.
Having two copies running at a time would be a considered a bug for cases like this.

sometimes you can create a timing window that will get two of these programs to run at the same time. you make a cmd file like this.
start c:\myfiles\myprogram.exe
start c:\myfiles\myprogram.exe

save the file as a cmd file like
mycmd.cmd
(make the cmd windows very small to make it run faster)
then run it and see if two copies come up.
the hope is to run the second copy before the first copy runs the code to prevent the second copy from running.
most likely effect is to just screw up the database and crash the first app.

here is code that can be used to prevent a second copy. older programs tend to not have very good code. they should run the code first.
