As I would be leaving for my CAS trip very soon, I decided to clean up my K750i memory stick so that I have enough space for pictures. I had only 15MBs left even when I had removed all the pictures. My Mp3s were only 20MB so what was taking rest of the memory? The file hierarchy of the phone had always confused me before, but today I found out most of the folders were junk.

The system folder was taking the most space so I checked it out, I previously thought that this folder would have critical files, essential for running the phone. But it turned out that most of the stuff is useless, the ams folder contained what seemed to be some program data of applications I dont use at all, or were removed from the phone long ago. Interestingly the muvee folder in ams had some .mrp files which turned out to be bitmap images. Just rename them to .bmp and you’ll be able to view them. This was where most of the memory was going. I also removed the SKINS folder, which seemed to have pictures aswell but I could not find any way to open .mbm files. I tried a tool mbmbmp but I guess SonyEricsson uses a different method to store data in these files.

I also removed some useless sound recordings and some .jar files I had in ‘others’ directory for the purpose of distributing them to others. I really like this feature of K750i that you can send out files in that directory using bluetooth and infrared, even if it is a jar. After only 25MB was used on my memory I decided to defragment the chip, yes it may sound surprising but phones can also be defragmented. This can increase the performance of your phone if you have a large memory chip.
