I think the key here is the definition of how exatly do I
my audio files, with SFK garbage between them
I select with CTRL + A in FreeCommander and then press CTRL + 1, which a shortcut set up in FC at
Customize favorite toolbars > Define favorite toolbars > Hotkey
with my settings dwn there like this:
Program or folder: C:\Program Files (x86)\Mp3tag\Mp3tagButton.exe
Start folder: %ActivDir%
Parameter: %ActivSelAsFileUtf8%
Enclose each selected item with "
where that Mp3tagButton.exe [How To - Start Mp3tag from Total Commander / FreeCommander] is used instead of Mp3tag.exe
I tried reverting to my old saved settings of FreeCommander, when I was using that Mp3tagButton- but I do not know why, they older methods [settings] of sending [with destination set to Mp3tag.exe] are not working completely. But I did try dragging and dropping, both from FC and Windows Explorer- and yes, then I get no such error, even with the same set of files
So it seems this is yet another problem about communication between different pieces of software. It could be the fault of FreeCommander or Mp3tagButton- but it is the Mp3tag itself that for the same file can produce or not produce that error. After all: the SFK file stays the same, as the location of it
