CapabilityAccessManager.db-wal file taking up all of my hard drive space - how do I delete or fix?

The `CapabilityAccessManager.db-wal` file is typically associated with Android's security and permission management system.



In Android, each application has a set of permissions that define the scope of actions the application can perform. For example, an application might require access to the device's camera, location information, contact data, etc. The Android system controls access to these functionalities through a permission system.



The `CapabilityAccessManager.db-wal` file is likely related to a database used to store information about application permissions. Specifically, the `.db-wal` extension suggests that it's a Write-Ahead Logging (WAL) file associated with a SQLite database.



In SQLite databases, WAL is a method of logging changes to the database in a separate file before applying them to the main database file. This logging method enhances the performance and reliability of the database.



Therefore, the `CapabilityAccessManager.db-wal` file is probably used to log changes to the permissions database (`CapabilityAccessManager.db`) in Android. This logging mechanism helps ensure the consistency and integrity of the permissions management system, allowing for recovery in case of database failures or interruptions.

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Recent File List

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file1

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file2
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file3
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file4
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file5
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file6
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file7
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file8
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file9
...

you get the idea. ( too lazy to put it in a for loop and test it.

or just open regedit and remove all the fileX from that key.
