If your NFC Tag List ends up like mine with hundreds of unknown NFC Tags (probably due to my Smartphone), there is no easy/convenient way to edit or shorten that list.
You need to edit an xml file placed somewhere in a hidden storage folder, and better not break that file when doing so.
You need to edit the file named “Tag” located in \config.storage folder. I use SMB File Share to access it.
It’s a simple Text File formatted with XML, so you can use any text editor.
Make sure to have a backup of that file before you start editing.
