Are you still having problems cleaning "others" folder?
If you have Spotify installed and use it a lot like me, you need to erase internal Spotify cache. For that go into Spotify settings, look for "storage" and press on "delete cache"; that is all; others will go down to 400MB and your kindle will recover its performance.
So, I know this topic is rather old, but I want to comment because it does seem that the "other" folder that takes up the majority of space comes from the above mentioned .estrong file/recycle bin. Basically the file size lies because it is hidden data. But, you can access this massive file and delete it all with a little elbow grease. Doesn't take an external computer or anything not found on amazon app. I used the ES storage manager app that's free and pretty popular .
My child's tablet had 17gb of the 24gb available allocated to this "other" folder and it was ridiculous. He could not play a single game. I felt bad for making him "delete" games he didn't want to play to clear storage. After a while it was down to 2 games at a time. Pointless device.
Anyways, the process to clean this is to download the ES storage app. Then share the content to the kids profile (if necessary) then open the ES. Might as well use it to clear out junk and whatnot while you're at it. On the main page of the ES app access the menu (top left) and scroll down to "show hidden". Then back at main screen swipe left. You'll see the "estrongs" folder. Open it and view the recycle bin. If your "other" folder is sizeable then it will take a while for the recycle to open. Then proceed to delete that garbage.
Hi, been trying to solve this problem for some time (Amazon are zero help!) Can I just ask is app called ES Storage manager? Can find ES File explorer (although NOT available for/from Amazon unsurprisingly!) but cant find ES storage manager for android anywhere. 🤔
I've had a similar problem with miscellaneous other files. I think my problem is exacerbated by FreeTime Unlimited and large games, particularly Minecraft Story Mode. Here's what I did to fix, or at least ameliorate, the problem:
1) Download CCleaner
2) Enable CCleaner in my kids' FreeTime account
3) Switch to their accounts in FreeTime
4) Use CCleaner
CCleaner did not find anything to remove when used from my account; I had to open and use it from their accounts within FreeTime. Their accounts had large APK files, which I removed. This freed up significant space.
Speculating a little bit, it seems that downloading large games within FreeTime is fragile. We've had Minecraft Story Mode fail to download multiple times (device is idle too long and turns off, storage drops too low and cancels the download, screen time for the day runs out, etc...), and afterwards the size of the miscellaneous other files always increased. The failed downloads aren't properly or regularly cleaned up.
A further complication to note: Even with large, empty external SD cards, Minecraft Story Mode won't download unless there is enough internal space. This happens even though once installed the majority of Minecraft Story Mode is on the external card. With an 8 GB Fire that only has a few GB actually usable and available, just managing space to allow the download of Minecraft Story Mode is a challenge.
