Disconnecting from my PC

This player cannot play mp4 files only mp3 files. When the files are copied to the MP3 player the computer can play the mp4 files from the MP3 player but when you play these mp4 files straight from the MP3 Go Gear it cannot see or play these files.

MP3 players can only play music files in mp3 file format. You can download mp3 music files from the Internet toyour computer and then copy them to your MP3 player. For your CD collection, you need to convert your CDs tomp3 music files onto your computer or download them from the Internet and thencopy them to your MP3 player.
You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.

Philips produces a variety of MP3 players that differ in capacity and design. All of the Philips MP3 players have one thing in common, however: the way that you manage files on the MP3 player. All Philips MP3 players appear as USB mass storage devices when connected to your computer. This means that you can delete files off of your Philips MP3 player using Windows Explorer, much like you would remove a file off of a USB drive.

To delete them, follow this instructions:

1)Connect your Philips MP3 player to your computer using the USB cable provided with your device.
2)Find your Philips MP3 player in Windows Explorer by clicking "Start" and then "My Computer." You should see your device under the section labeled "Devices with Removable Storage."
3)Double-click on your Philips MP3 player to view the files stored on the MP3 player.
4)Navigate to the folder that contains the files you want to remove. Your files are organized based on the type of file. For example, open the "Music" folder to delete music files.
5)Right-click on a file you want to delete and select "Delete." Click "Yes" when asked if you are sure you want to delete the file.
6)Eject the Philips MP3 player before disconnecting it. Click the "USB Mass Storage" icon in the system tray and select "Safely Remove Hardware." The system tray is in the lower-right corner of the screen.

MP3 players cant be used with itunes, Itunes is only for Ipods and such.
Just see where you download the actual songs. and put them in a folder and copy the songs into your MP3 player.

Or you can also try right clicking on the song in itunes and then copying and pasting it in the MP3 player

if you formatted your mp3 (you deleted not only the musical files, but the software to run your mp3)...if by any chance this is true and a friend / family member of yours have the same exact mp3 player. you can ask can you copy their software............this what you do, take their mp3 plug it up to your pc (copy only the software check for hidden files also)...disconnect the mp3 and give them back their mp3 (we dont need it anymore)...plug your mp3 to your pc and copy all the software data from pc, you just copied ....on to the mp3...and put your music back (put all M. Jax (R.I.P.)) ...........if this is helpful feel free to rate

have u tried opening the mp3's folder files and dragging the music in there?

Create a folder on your music player called System. Copy over the Font and Firmware update into this folder. Disconnect and then reconnect your mp3 player. It should then recognize it with Device Manager software. This took me a good two hours to figured out.

First You need to connect your player to the computer using a USB cable. Most mp3 players will be shown as a removable disk drive in my computer as soon as they are connected. Just copy and paste your mp3 files on to it. Dont forget to use safely remove hardware option before disconnecting it from the computer. Also if you got any software with your player on a CD i recommend that you install it on your comp so that it will help you organize you songs in a better way.
