HEYA


First of all open itunes

Link your MP3 player to your computer while the iTunes software is loaded on the computer. By itself, iTunes serves as an audio player for your computer. You can transfer audio files to your MP3 player using a USB cable which comes with most MP3 players. Your computer will prompt you to name your MP3 player, and an icon identifying it will appear down the left margin of iTunes.


Click on the MP3 file (the song), and drag it into the "Library" folder in iTunes. This folder will serve as the general place to store all the MP3s on your computer. From there, you can create new playlists to select specific songs, click on the "shuffle" option to have iTunes randomly select songs to be played through your computer, or play every song in order from the library.


Select the appropriate song or playlist, and click the "Play" button on iTunes to listen. Or drag the songs from iTunes into your MP3 player's icon in iTunes to copy the song into your MP3 player.

Long live the geeks!!!!!!

Plug the device to pc, it will appear icon "sansa clip..." or removable disk, double clip on that >> double on Music folder >> drag & drop songs from Music to pc.

Do let me know if you need further assistance.

I had the same problem two days ago.

Working on the assumption that the problem was a corrupted file, here's how I fixed it. As you'll see, I connected my Clip an Macintosh computer to fix it, but there is probably an analogous procedure using a PC. But I'm not very PC savvy, so someone else will have to figure that out.
Also, I don't know that all the following steps are needed, for example, trashing the old content folders and creating new ones, but this is what I did, and success resulted:

Connect Clip to Mac

Click on Clip's icon to open it.

Open up all content folders and drag songs, audiobooks, podcasts, etc. to trash and empty trash. (The idea is to get rid of the corrupt file, wherever it is.)

Drag all Clip system files to a new folder on the Mac desktop to copy them. This will include DID.bin, RES_INFO.SYS, SYS_CONF.SYS, version.sdk and WMPInfo.xml (Basically, I copied everything that wasn't a content folder.)

Don't bother copying content folders AUDIBLE, AUDIOBOOKS, MUSIC, PODCASTS and RECORD. (Later, you'll create new folders to replace these, to ensure that no corrupted file is reloaded to the Clip.)

Go to the Mac's Utilities folder. Launch "Disk Utility." Select Disk Utility's "erase" function. On the left, where disks are listed, select the Clip. Click on the "Volume Format" dialog box and choose "MS-DOS filing system." (Don't bother with any of the erase options, such as replacing all data with zeroes. Just do the basic erase.) Erase the Clip.

When erase is completed, drag copies of Clip's system files from Mac desktop back onto Clip icon.

Use "new folder" function to create new AUDIBLE, AUDIOBOOKS, MUSIC, PODCASTS and RECORD folders on the Clip.

Eject Clip from Mac and note whether the screen shows the Clip "refreshing" normally. If it does, you're in business.

make sure its pluged in.

Yes the setup.exe might show up as setup, in most home computer the settings are set to hide the extension (after the dot) so make it simpler.

Here is a general quide, select your model and follow the instructions It should start working somewhere along the way.

Follow up to the instruction given by rtujillo. Change the settings of the player to MSC (SETTINGS>USB MODE> MSC) connect the player to the computer and you should see the player listed in the My Computer window with a drive letter. Now just drag and dropped the songs to the player. The songs file format should be compatible with the player.
