Gallery preview folder takes about 1GB, how to delete it? I've got a Samsung Galaxy S2 Plus (GT-I9105P) with Android 4.2.2 and I've got many photos. The folder with the Gallery previews (the one that stores thumbnail to load images faster) takes about 1GB of storage (815,9MB, precisely) and if I delete it, when I open the Gallery app it recreates.


Here you can see it (click image to enlarge)

"Anteprime galleria" in Italian means "Gallery previews". The folder itself is called "DCIM" and it's in the phone's memory (All my photos are in teh SD card) and it contains an hidden .thumbnails folder.



So, how can I delete it and make sure it won't recreate?
Do you really want to do that? That might lead to you no more being able to see your images in the gallery. But if you want to try:


open a file manager of your choice and navigate to the DCIM folder
delete the .thumbnails directory
create a file named .thumbnails
open the file's properties, and set it "read only"


Now, as there cannot be two objects with the identical name, the gallery cannot re-create the folder. As the existing object is a file, it cannot put its thumbnails in there, either.
