In what folder did you move the mp3 files ?
Did you create a new one ?
Did you set the folder options to “Show invisible folders” or how that is called ?
In which USB mode did you move the files onto your player for the first time ? In MTP or MSC ?
I have the same problem, im in MSC and i tried the option of viewing the hidden folders, but still i can’t see the songs on the device. The first time i use the device i put all the songs in a folder called something like “For music files” or something like that, and now i can’t find it. The folder was already on the deveice, i did not create it…
Can you listen to your mp3 files via the player ?
If so the files must be on your device.
If not just forget it, create a new folder “music” (it´s important to create a new folder!), put the files from your PC to the m240, that´s it.
Yeah, the files are on the thing, but i can’t really access them anymore, i can’t erase them or move them, they are just taking up space there… This is really wierd, i bought the thing to be easy to use, but this is just giving me headache after headache…
