Return to initial

moonsky

hello admin
After using it, I made many attempts to learn and install the application and then delete it. After repeating it several times, I found that the file system was a little messed up. So I wanted to return to the initial state and reinstall the application plan, but I could not find this function. Even if all applications are deleted, many resources are still occupied
Can you suggest adding this function: return to the initial state?
Or is there an instruction that can complete this functional requirement?

Hello,

If you are writing about used space: log in to SSH and check the space occupied by directories on the account, including directories with a dot in their name.
