When the contents of an external USB drive is copied onto another external hard drive, there is one thing to be careful about. If the song files in the original external USB hard drive are in a folder along with English.inx and juke.txt files, they can be copied to another drive with no problem. However, when the song files in the original USB hard drive are inside a subfolder _Songs and the files English.inx, juke.txt and Address.inx are together with the _Songs subfolder, then after copying the contents to a new hard drive, you must run INXmaker program on the file juke.txt to recreate the Address.inx file in the new drive. Â  Address.inx is a file that keeps record of physical locations of all songs.Â  So copying the contents of a hard drive to another make this Address.inx file useless.Â  That is why we must run INXmaker program again on the juke.txt file in the new hard drive to recreate the Address.inx for the new hard drive.
