Can't open filenames with certain characters in folder name

'D:\?\' is not a file, there is no extension, and if there were an extension '?' would select all files with that extension that have a single-character filename on the D:\ drive, wouldn't it? Or am I missing something??

Otherwise, XnView Classic does not support Unicode characters, use XnView MP for that.

There are also various other reasons why an image file might not open, such as the file being malformed, or a required plugin not being installed.
