Ok to delete?

[jpstarn]

I've moved all of my photos to the sd card on my phone. Playing around in files, I found a thumbnail folder under device storage, DCIM. It's thumbnails of all my pictures. I deleted a couple from the folder and haven't noticed any change in my gallery. Is it OK to delete all the thumbnails? See screen shot below. Thanks! Still learning androids, lol!

Yep but pointless as the system will just recreate them when you look at any of your pics in the gallery. You do know what thumbnails are for right?

what are the thumbnails for?

what are the thumbnails for?

They're ultra-low-res representations of the actual photos and videos stored in your phone. As the actual media files are typically saved at a relatively high resolution, for apps like a photo gallery or file manager to be able to quickly present you with a pseudo-contact sheet of your media files they rely on these low res 'thumbnail' images. The thumbnail folder may appear to be hogging up storage space because it may hold hundreds or even thousands of files in it but they're all pretty small in size. Even if you wipe the folder clean it's just a short term fix as the first time you start up an app that needs those thumbnails, they will just get restored again.
