Sorry towards everyone who might be bothered because this topic was already finally discussed - I didn't find the thread in this case. (I generally struggle with specifically searching for XnView MP content on this forum)
Because my scanner can produce multipage TIFF files, and the ScanTailor forks out there like it, I prefer this format.
XnView Classic provided tools to e.g. delete pages with a GUI: Tools | Multipage file | Edit Multipage TIFF or Ctrl+J shortcut.
I cannot find the same thing in XnView MP. I think this is the last reason why I keep XnView Classic installed.
However, XnView Classic is restricted in dealing with Unicode paths or filenames. Since I often use symbols in paths & names, I need to move or rename the files in such cases. I would clearly prefer to have the functionality available in XnView MP.
So I post this under General Support because I'm unsure whether I just miss something. If it was just omitted until now, I would probably need to make it a suggestion.
