Android has a method to directly hide folders without any other operations.\ For example, if you want to hide a folder named '7723', you just need to add a '.' in front of the folder name.\ For example: '.7723'\ After doing this, you will see that the folder disappears (it's actually hidden).
If you want to find this folder again, just download a third-party file browsing app (both file browsers and archive managers work, which almost everyone already has on their phone!).
This way, you can easily hide folders without needing third-party software.
