Your MP3 files will easily occupy several hundred megabytes of disk space if not more.
So the USB Flash Memory would be impractical.
There are several methods:
1. Burn the mp3 files onto CD-Rs which IMO is the best method as it also provides a backup for safe keeping. Then you can copy them over to the new PC.
2. When you have the new PC set up a network between the two and copy over the files from Old PC~New PC over the network.

3. If you want to transfer both your files and customized settings, emails, favorites etc. from the old PC to the new PC you can run the Files & Settings Transfer Wizard on the old PC and restore the backup onto the new PC.

4. Pull the old HD and slave it to the new PC and directly copy over all your files.
I am getting a new computer, the old computer is going to my daughter. I would like to transfer my MP3 files to the new computer. What is the easiest way? I have seen some migration software, but seems somewhat unstable. Have seen the new USB flash memories, wondering if those are an appropriate option? Any other suggestions appreciated???
