Your problem may be that your Coby MP601 does not support the file format of the file that you are trying to put on it.
They Coby MP 601 only accepts the following formats: Audio- MP3, WMA Video- MTV, MP4 Still Image (Pictures)- JPG
Check your file. If the three letters after the period do not match one of those letters above, the file format is not supported by this MP3 player. For example, an image title may be "IMG00658.JPG", but not "IMG00658.GIF".
To change file formats, there are hundreds of file converters that you can find on download.com for audio, video, and images. Once you have the correct file format, you should have no problem putting it on your Coby MP601 MP3 player.
Hope this helped.

All video files , even the mp4 files need to be converted using the Sansa Media Converter. It is a free download.

If your not using version 2.20 then upgrade because there is no limit according to the manufacturer.

JPEG, TIFF, PNG, BMP, GIF

You must use the Sansa Media converter to convert the pictures into the proper format. The media converter will not recognize ALL picture types pre-conversion, so you will have to check your manual for the list of compatible file types. In general, if the media converter won't find the file in the folder in which you stored it, then the file cannot be converted AS IS. The solution would be to convert the file to jpg or bmp format, and then run the file through the Sansa Media Converter.

well first of all, I suggest that,, convert first the song or video that you have downloaded from other sites, it's file type maybe such as FLV file,, or flash video file,, convert it to WMV, WMA, or MP3 then after converting it, try to drag it to your collections then right click sync, then,, I think that would be the time that it will be saved unto your Zune Device,, Note:,, Zune only supports file types such as WMV, WMA, MP3, and JPG,, SO be sure to convert the file first to any of those supported files so that it will automatically be saved unto your Zune Device,, if you have more questions,, just email me at,, [email protected]
