Nextcloud – How to delete files or folders that are locked

• Check and disable all active file or folder shares
• Locate the config folder of your Nextcloud installation and open it.
• Find the file named config.php and right-click on it. Select Edit from the menu.
• In the editor, look for the line that says 'filelocking.enabled' => true, and change it to 'filelocking.enabled' => false,
• Save the file and exit the editor.

N.B. If the value ‘filelocking.enabled’ => false, is not present, add it to the end of the config.php file

E.G.:

……..
‘maintenance’ => false,
‘theme’ => ”,
‘loglevel’ => 2,
‘filelocking.enabled’ => false,
);
