Set CACHE folder

[gasparirob]

Hi all, I've just a little problem: my "Flash Disk" quickly becomes full, 'cause "Pocket ImageViewer" creates thumbnails just here!
TomTom too uses this memory to save preferences. So, everytime it displays an error message due no space on Flash Disk.

Is there a way to set a different location for cache folder and put it in external memory (SD)?


Thanks in advance
