You have given these detail.But actually no need to put this.the only question is which memory status that you are mention here..is it for phone or mmc(Edrive)?anyway here is the trick don't bother for mmc memory you just consider the phone memory.First make backup all the important data like Contacts,messages etc. which is in the phone memory.and try to format by pressing *#7370# and put pin code when ask.

Write your phonebok to the paper & other important information, Then try to delete it all jus to free your memory (empty) or REFORMAT, then you may return to download, or delete only the unnecessary videos, image, mesgs. & unused program that you download, Then download skype & other important program to your cellular, Note: always check your memory content, Always have an free allowance to download in your memory at least 50 to 25 percent free.

delete the extra files of the areas which cover major portions of the memory

if its chinese phone then it will always show 7 gb used out of total of 8 gb n u wl get a space of 1 g.b thanksssss

U delete ur data like calendar entries etc.. Aftr it u download netqin mobile guard.. By it u cn dlt ur all othr files.. If u want more info then contact me [email protected]

In ur Phone memory only 170 kb is free . so, delete some data in phone memory or change datas to the memory card. Then u can receive messages

1gb of memory is not a lot when it comes to videos. 1 gigabyte is roughly 1000 megabytes and a movie can take up 850 megabytes! Make the videos are a format it can play and that they're the right size to play on that screen. You can download free video resizers.

i) it has nothing to do with the number of songs(like you said 188 songs,,,, 15 picturess... or something like that ), it depends on the storage capacity of your memory stick(2 GB) 

ii) some songs may occupy more memory, so may occupy less memory....for eg: song1: 10 mb, song2 : 3 mb; .....

so i would suggest to store some songs(not numbered ...depending upon their capacity and suffiencecy of your card....)
