Hi, I was just thinking about reformating /home/user/MyDocs/ partition to ext* because of the tile's size (also because of directory linking, permissions...). On n900 I have 9.4G of OSM tiles (du -h) the same on my PC with ext3 takes 1.4G and apparent size on PC is 1.1G And my PC has 4096 block size. Interesting. I did all in the first post on my PC (with 1024 blocks) and the first thing I see is that the empty 4G file reports 3G free space after mount (on PC). After tile-files copy - du says 1.2G and apparent size is 1.1G. So - (before copying this 4G file to n900), the main problem is the size 3 out of 4G. This I dont understand. It looks like one block takes 256bytes?
