copy policy to prevent fragmentation

[eadmaster]

Hi, i'm thinking about using a stack-like (LIFO) copy policy to prevent fragmentation on the SD:
1. format the SD
2. copy game A
3. copy game B
4. copy game C
etc., until the space is filled

later, if you need some free space always delete the latest games copied in reverse order.
(you better keep a list on a txt file to remember the copy order)

questions:
- Will this policy serve the purpose of preventing fragmentation?
- Can you suggest a better algorithm?

if you copy one game at a time it will eventually get fragmented, i've already tried that

just copy them all at once

32gb card can fit about 40+ games (shrunk/etc), why ever copy again?

no and no.
the problem is in the filesystem and/or operating system itself so there's really no way to stop files from fragmentation. if you really want to have a go at this, you should start at the swiss source, not the other side

uhm, maybe flash memory is different because of wear leveling.

So, the only "safe" way would be doing a clean format each time?

i don't think that you need a format every time you change the games. might be for flash memory but with HDD you sure don't need to, because i never did
