Move DCIM .thumbnails to external SD My phone has 1.5 GB internal memory and it's always full with gallery thumbnails (500 MB) . Every time I delete it for more space after one day it's full again . 

How can I move it to external micro SD memory ?
Moving this folder to sd woun't help, cause android would recreate it. For me, this folder is shown as 6.5 GB (the real size was aprox 80 MB).

WorldCAD Access posted an interesting solution, how to prevent Android for recreating at least the db files.

Another soultion, if you have root access would be to symlink this folder to sdcard. You can do this via command line or using tools like Link2SD or FolderMount.

here you also can find some suggestions/solutions.
