Your files in MMC are stored in multiple (disk) blocks.
So if you format using 16K block, the space used will be 16K eventhough your file is just 1K.
If you buy MMC, it is usually preformatted with 16K block. Therefore alot of space is wasted as mostinstalled program files are usually less than 2K.
You will need a card reader to do this:-
1. Connect card reader andcopy all your files in the MMC to computer disk. (Make sure you set the show all/hidden/os files to"on")
2. Do a format of the MMC using command line"format" and use the /A=size option.
Alternative, you can use the Disk Management in Adminstrative Tools to format. Make sure you select FAT. For 256MB MMC,smallest block you can useis 4K, 128MB is 2K, 64Mb is 1K and 32MB is 512B.
(Note: You cannot use the phone "format MMC" to dothis as the format just clear the allocation table and does not change the block size)
3. Copy back all files to MMC.
Now you will find that youwill have more space.
256mb MMC got back 30 mbs
