'invalid file format'

Without a specific description of the file format or file size limit, a good way to test what works is to create some very short files saved in different formats on your PC then load them on your memory card to see which ones work. Usually formats like .WAV, .SND, and perhaps some others may work. They can be easily saved to test on your PC.
The main SAVE AS considerations are:
Extension;
Format: as in PCM, and about some 18 others; then
Attributes: frequency, bit-rate, and Mono vs Stereo

Windows basic sound Recorder will let you load a sound file and save it in different formats [with some limitations] but enough to experiment.

MP3 players can only play music files in mp3 file format. You can download mp3 music files onto your computer and then copy them to your MP3 player.
For CD disks you need to convert your CDs to mp3 music files onto yourcomputer or download them from the Internet and then copy them to your MP3player.
You can do this using Windows Media player and Rip the CDs - Media Player willcreate a MP3 music file for each music track.

You will first need to delete all the music from your MP3 player that you put on it. Use this method to do that: Hook up your mp3 player to your computer Go to your desktop and double left click on "My Computer" When it opens you will see listing that says "Devices with Removal Storage" your mp3 player should be listed there. Right click on your mp3 player, and a window will open, right click on "Open" and now your files/songs should be visible. Hold the left click down and drag it across all the files/songs that you do not want this will highlight the files/songs you do not want, release, right click and then click on "Delete" Now you mp3 player should be clear of the files/songs you do not want. BE CAREFUL AND DO NOT DELETE THE FILES NEEDED TO OPERATE YOUR MP3 PLAYER. ---------------------------------------------------------------------------- I tunes is an AAC format, it will not work with your player... You need WMA format to make the songs work on the GPX-MW3836 What you can do is covert the songs from ACC to WMA using a format converter. Then put them in a folder/file and drag and drop them to the player, or download the songs to Windows Media Player after you have converted them and then download them to your player, as Windows Media Player is WMA format. ----------------------------------------------------------------------- You can download a free format converter at this website: www.formatoz.com/ Good Luck, I hope this helped Please rate me, Thanks

i have used quite a few mp4 players and encountered this problem several times - the solution that worked for me is :

Format the drive when it syncs to your computer -- a quick format will do and then it should let you copy the songs to it

just in case you don't know how to format it

1) Right click the MP4 player drive

what type of mp4 player is it, and what type of files are you trying to upload?

The device itself is not faulty. This is Microsoft's fault, not Philips'. Some of the songs may have Digital Rights Management (DRM) encoding that the SA6025 will not support. You can right click on the trouble music file, select "Properties," and select the License or Digital Right tab - look for the msg: This file is not copyright protected. Find out if the songs that CAN'T be transferred have this message. If so, then click on acquire digital rights (or some variant of that phrase). If the files tha CAN'T be transferred DO have Digital rights protection, then you must save the files in a different format that is stripped of DRM encryption.

There are a few possible answers:
1)Start simple - disconnect the GoGear from the computer - let it update - then reconnect it to the computer; if this fails, restart your computer and try syncing again

2)You need a firmware upgrade to make the device compatible with your computer: just open up Philips Device Manager (Start --> All Programs --> Philips) - if you don't see it, then re-run the installation CD or grab the "Device/Firmware Manager" from the Philips website; click on the update tab

3) The songs have Digital Rights Management (DRM) protection.Try re-downloading the songs without DRM protection.

4) The songs are in a format not recognized by the GoGear. The GoGear, for instance, will not take iTunes files b/c they are AAC format. With MP3 files, the player supports 32 –320kbps. With WMA: 5-192kbps with sampling rate 8.0kHz up to 44.1kHz. Right click the song file, and select "Save As", and then change the format of the song file. Or, redonwload, in the above-said format.
