Your MP3 player expect files properly encoded as MP3 files, and some can also read WAV and WMV audio files.
In this case, the exact brand and model don't mather, and the following does apply to ALL players and ANY version of Windows.
There are similar resources for Macs computers and Linux ones.
If the files are in a format that don't match the extention, those simple devices can easily get stumped and give up. It appens if you only rename the file to change the extention.
Now, what did you use to copy your CD's in your computer? If you got CDA files, those are realy only shortcuts to the audio tracks on a specific CD. NO player can play those from anywhere other that the original CD.
You can use FreeRip MP3 to correctly convert your CDs into MP3 files that can be played on any device.
("rip" is the term used for the operation of extracting the content of a CD or DVD and save it in digital format)
It can be set to fetch the CD's informations from some internet database to correctly, and automaticaly, name the various tracks.
A quick search will return several other MP3 encoders, some free and some that you need to pay for. Some of those can take a CD and rip it as a single file containing all the tracks.
