Defrag on SD via PPC program is not really useful and the quicker and safer way to clean up is doing this way:
1. Copy all content to PC via a good SD card reader.
2. Reformat the SD card from the PC
3. Copy everything saved to PC back to SD card.
It is a lot safer to do this way then trying defrag the SD card.
Man, shurely it's safer but in some cases penalize the performace !
The writing process randomly write fragmentend .. and you never predict before the file/s affected.
Now, the most part of times this is not vital, but sometimes you notice a big performace degrade. It's depends, in part, by vital, important and/or more usued files fragmentation !
After doing what you wrote, you'll notice that th card is fragmentend, expecially if you almost fill it and there's a condition to copy big files at the end of the process where the empty free space on card is little and spread in several little blocks !
Believe man, It's a tricky but usefull feature !
