I have a mp3 that has 945 mb, when i delet songs the space taken is the same.

sir, as there will be a usb cable given along with the device, you should just connect that tothe computer. a window will open showing the already containing songs.you can just right click on the selected songs in that window and select the delete option.the songs will be deleted.

That's because no offence but it has rubbish memory. 25mb is nothing these days. Most songs are 9-15mb themselves these days, and so no wonder you have no space left.

Delete some files to get room for your new songs

Three possibilities:
1) your music service subscription expired (or the license on your songs expired) - solution: update them
2) You switched from msd to mtp mode - solution: switch to AUTO
3) Your DB has been corrupt - solution: update the firmware from the manufacturer's website, or format the player - see my help file on this under my profile

need make and model

Well plug it into the computer right click on the sansa clip and format it if it wont start then restart it by holding powre for about 10 seconds or so. then try to turn it on...if the thing still wont work download jet audio.(http://www.download.com/JetAudio-Basic/3000-2167_4-10783427.html?tag=lst-1)
and once thats done. you should take all your music on the mp3 and put it onto the desktop in a folder named MUSIC then highlight all the music right click should say somthing about jet audio and edit tag with jet audio then delete Tags....i know this will be the crppiest thing to do cause you have to fill in all the info. this also fixes the frozen refreshing database thing. hope it works

I believe you have to delete the songs from your computer

Try formatting it....when you right click on the sansa image on ur comp...click format

I had the same problem. In the end I reformatted the e200. To reformat hook up to your pc and there should be a reformat option on the e200 icon.

Have you tried formatting the unit if not try that it should work.
