Why am I getting these weird hidden folders with long numbers after every restart

[Black Falcon 1991]

Every time I restart the phone, I get these strange hidden folders. I haven't downloaded anything odd, visited dangerous sites. Just restarted the phone.

Can you please tell me the name of those hidden folders?
Because I once had problem like that, but Im not sure it is the same one.

They're named something like this - .1458841825427, it mostly starts on the micro SD.

You can probably safely delete those folders, but I just leave them where they are because they don't consume too much space.

In addition, if you have trouble like this in your PC. Just run DISK CLEANER.

Thanks MastermindPrototype, I'll work with my storage and see what happens.

Ur welcome
By the way I recommend you install Avast Cleanup.
This program will help you clean up those folders.
