I think the thumbnail file starts growing again.


My phone is Sony xperia sp. The thumbnail file keeps on growing again. What to do?


My phone eon't ler me create a file with the same name. :(


Thanks for the support . It helped me to get extra 2.5 GB space internal memory. Great article dude... :) Pandu


Whoa! I cleared 1.8 GB of space!! There were two thumnail files.

Thanks for sharing!


It don't last.

The file gets bigger after a while (a few days)


Thanks but I'm using nexus5& 7 the file come back after you view your gallery again .there's got to be a way cause I was 5to 8 GB with this .you find another way please let me not thanks


Can u believe how much data I had 9 gb. Yes ur right why android is doing this. Pls. Remove this bug.


I have Sony Xperia L. Above procedure of deleting thumnail file & creating dummy file with same name works only for 2-3 days, the mobile agains creates thubmnail file of 2gb. Is there any permanent solution to this?


Guys I renamed parent '.thumbnail' folder to '.thmbnailqq' & this itself solved this problem :-) try it out.

That was the best instruction for a slightly technical programmer-y process I've ever seen in the history of the internet!

Thank you, kind genius.

Followed your steps to a T and, if that thumbnail creation business stops, you just got me back 3.2gb on my annoying Nexus 4--Don't get me wrong, I love the phone, but the no external memory business has been such a pain over the last year that I'm probably ditching Google devices.

I would love recommendations on possible replacement phones, as I am due for a new one and, as I said, am not interested in phones that limit you to XXgb+Cloud. I shudder to think how much time I've spent managing storage capacity issues on the Nexus 4. Never again!


When I even take a screen shot the same dummy file I made just grew back in size and toke up back all my memory again pls help!!!!!


Also, move any downloaded files over to your SD card. I had this problem because I kept downloading music and movies. Also deleted the thumbnail files but it didn't really show that I made space just yet maybe because I haven't disconnected it yet.


For deleting the thumbnails you need to follow the following steps no need to download any app for it.

1) create a new folder on your desktop, inside that folder create a text document and rename it as .file

2) make as many text document files with extension as .file as there are .thumbnail files under your DCIM folder => .thumbnail files and rename the text document files with exactly the same name as .thumbnail files (or you can make some text document files and rename them again and again with the new .thumbnail files).

3) delete all the original .thumbnail files and replace it with the new text document files that you made with the extension .file

4) reboot your phone and you are done.


Finally! Something that worked. I have trawled the internet for a workaround with this thumbnail problem and I was getting to the point of sending my phone back I was so frustrated with this. I am not a techie in any way shape or form and your instructions were easy to follow and it has actually worked. So relieved. Can't thank you enough :)


I'm using Thumb Space, from the Google Play store.. it does the job with one click.
