Now sonicstage gave me a headache when installing so I came with an alternative. This method is meant to be used on linux but it works on windows as well.
This should work on Sony NW-E002 , Sony NW-E003 , Sony NW-E004 and other Sony players.
Things you’ll need:
1. Install Java.
2. Format your Sony mp3 player. (Options > Advanced > Initialize > Format > Ok on your player)
3. Insert the player to your computer. Copy NW-E00X_MP3_File_ManagerXXXX.jar to the your player. Also copy OMGAUDIO folder to your player, make sure there is no OMGAUDIO folder inside OMGAUDIO folder (it can happen if you extract to OMGAUDIO\)
4. Click Start > Run > CMD
5. Once on the commandline console type the following and hit enter. J: is my drive letter for the player. You MUST replace it with your players driveletter.
java -jar NW-E00X_MP3_File_Manager-0.17a.jar
The 0.17a is the version of the file manager I’m using. If you have a different one just use it. On the console you can just type java -jar NW<tabkey>
Once that starts just browse your music and click the Down arrow at the left and click on save at lower right.
PS: If you get a No Database on your player. Format your player on your computer and you’ll get a Format Error on your player. Next you format it from your player (Step 2) and continue from Step 3 to put your music. I know this is not the right way to do it but SonicStage won’t work and it is the only way it worked for it.
