Out of memory on voice record

I ran into a problem on my c250.  I was doing a voice recording and received a message that I was out of memory.  I’ve cleared the files out of the unit so the “voice” folder is empty but I still get the same message.  The unit has just under a gig of free space with all my music still loaded.  How do I get the free space back for voice recording?

never heard of that!

Backup ur music, then reformat from settings, format.  Then try voice recordings without any content on it, if that works - then put your music back on it, and try voice recordings again.
