My phone is xperia Z1. When my storage is full, I found that there are two big files in Card, \DCIM\.thumbnails: .thumbdata3-1763508120 (3.95G) .thumbdata3--1967290299(4.02G).
And when I delete it, the storage will not change, it didn't release any space, I still only have 600mb space. And after 1day or 2days, the two files:.thumbdata3-1763508120 and .thumbdata3--1967290299 appeared in \DCIM\.thumbnails again, even became bigger than before.
So I search lots of methods for these two files online. most of them did not work.
I bulit two empty files which have the same name with .thumbdata3-1763508120 and .thumbdata3--1967290299, and then delete the original big files in the .thumbnails folder, and repalced these two empty files with the same names into it. But after that the space also didn't change, what so funny is, after two days, the two empty files became to the original 2 big files(each one has nearly 4G) .:smileyshocked:
And don't know Why when I delete these two files, though I can't found them anymore, the space they take isn't free out. I believe that after I delete them, the two big files are sent to some system folder for backup use and protected by the system, then it will recover them again even I have replaced them with the same name 0kb files!
and one more thing is that I didn't found the folder named LOST.DIR in my card.
Is it a bug? could anyone help me with this problem??? They take me nearly 7 GB space, oh, my god, I can't even update the walkman due to low space now !!!!:smileyshocked:
