File Names too long - following an attempted backup

[linx4]

Hi, I recently had computer issues and I decided to copy my music files on to an external hard drive. I now wish to access the files, but when I try I get a message that the file name is too long and the  file(s) will not open. A more worrying aspect of this issue is that some files appear to be empty. If anyone out there has a solution to this issue I would be very grateful your for assistance. 

Thank you

linx4,
Please provide information about what operating system you are using.
Also, what backup program?

Hi,
I am using Windows 10. Foolishly I didn't use a backup program, just copy and paste from the computer hard drive to a blank dvd disc. Then the data was copied and pasted again to the new computer HD. Other files went over OK, but the music files did not and I am now unable to open them because the file name is too long. I believe that this error has been caused by the system  repeatedly accessing the files and adding to the file names. However, although I believe that to be the cause of the problem, how to cure it is unknown to me.
