There must be a way to rename your music files in Limewire 4.12 because if you "right click" on a music file ,one of the drop down box options is "rename".If you click on "rename" it will allow you to change the file name to what ever you want.Now here's where the problem starts,it is "keeping"(RETAINING) the "changes" you have made to the music files name.What is the next step in "renaming"???Push "enter" on your keyboard????It doesn't work,file reverts back to its old file name.I had a friend who can make the new file name changes work ,without adding any additional software program to Limewire 4.12.I wished I would have paid more attention to the "process procedure" involved.It has something to do with "shared" and "not shared" file folders and "imcomplete file" folders, he passed away unexpectedly,and took the answer with him unfortunately,his nickname was "Doc" and he was very intelligent when it came to solveing computer problems.My computer misses him the most,ha!So if there's anymore "Docs" out there in cyberland,your imput would be greatly appreciated,Thanx The Sturgeon General.P.S.If you live in the Sacramento-San Jaquin Delta(Bay Area) the solution is worth one Sturgeon fishing trip.
