[General-discussion] adding files to one of my folders?

[Dj Liqid Touch]

I have been trying to add a file to my Dj Mixes folder in SAM and its not 
adding.
I dont understand it.
Its an mp3 because it was recorded as one, and other files created exactly 
the same way were added to this same folder previously.
Either way, i try usingthe ADD FILES option as well as DRAG AND DROP but its 
not adding in.
I thought itwas going into another location but no.... when i do a search in 
MUSIC ALL it does not show up.
