Add to the above you can:
- record directly as mp3 (and can choose the bitrate), or WavPack for lossless compression
- set an own recording directory, which can be on the microSD(HC) card...
So there's lots of long meetings you could record, maybe have a look into the Rockbox manual for your player. Be aware though that Rockbox only works on the v1 range of the c200 models and if you just bought the c200, then there is a not so small chance you have a v2 one. The safest way to tell is to look at the version number of the original firmware - version 1.xx.xx is a "v1" and version v3.xx.xx would be a "v2" model.
