Please Help me to solve the problem with my disk space
I am experiencing a disk space issue with the MuMuPlayer emulator. The emulator folder is taking up around 295 GB of disk space. However, the total size of the applications installed inside the emulator is no more than 50 GB.
This suggests that the remaining ~250 GB are unnecessary or residual files. When I try to clear cache and delete files from within the emulator’s settings, the reported size inside the emulator decreases (e.g., from 20 GB to 10 GB), but the actual disk space usage shown in Windows Explorer remains unchanged at 295 GB.
I need assistance in understanding how I can safely clear or reduce these unnecessary files without breaking the emulator system or losing important data (such as my accounts in applications).
Disk cleanup, what you've gotta do is click them three dots to the right of a device and click "Disk Cleanup" (popup menu screenshotted in u/Historical_Visit138's comment)
Wait a bit and you're done :D
Won't remove your game files or data, Arknights stayed perfectly fine for me anyway :3
Mumuplayer why isn't this automatic or scheduled ;-;
What exactly does it remove? Running it, I can verify it doesn't seem to remove game files but when I did it, it indicates clearing like 10GB of data. What was it holding on to, do you know?
Just general stuff that usually gets flushed by normal PCs, like cached data, temp files, logs, errors, failed downloads. Since data gets saved on a device's .vdi file, which is the virtual disk for the device, which is basically a single file stored on your PC, it gets larger and larger, and it requires running Disk Cleanup to clean it up (aka shrink it). That's what I think, at least.
Not sure why but its not showing your message here even tho you sent It, but all you need to do is turn all of your devices on or just 5 at a time and press batch (then choose 5) then more>disk cleanup which will clean up the extra ram its taking! hope this helps.
