XnView Software

Nconvert v5.54
XnView v1.97
GFL SDK v2.90

Yes, -xall -multi and -xall yield the same results for me. ".tif" and ".tiff" are also treated differently.

I used -xall -multi -rotate 90 -c 7 -one_strip

All of the single page .tif convert correctly: filename.tif converts to filename.tif
On multi page, only the first page is converted: filename.tif (multi page) coverts to filename-0.tif (single page)

Thanks

edit: If I change the file extension ...

I would like to rotate all the pages of the TIFF 90 degrees clockwise.
