Where the file editing

Good evening

When I edit the tag from the app
And save it
Where can I found the file?

It's basically at the same location you've added it from.

I did not find it
You mean in the same app ?
Could you please explain it by picture ?
Thank you

It saves the tag data inside the original music file, it isn’t a separate file. It should be wherever it was before any changes, unless you moved it as part of your edits.

How did you look and test it?
