JUCE is an open-source cross-platform C++ application framework for desktop and mobile applications, including VST, VST3, AU, AUv3, LV2 and AAX audio plug-ins.
I used RangedDirectoryIterator() to iterate over a directory with a file whose full path name is longer than MAX_PATH. That worked properly, but the returned File object isn't functional, e.g., existsAsFile() returns false, and reading fails.
A workaround is to create a new File object, prefixing the path name with \\?\.
This was apparently also encountered by multiple users in the forum.
What is the expected behaviour?
Deal with long filenames
Note: On new enough versions of Windows this can apparently be handled without prefixing \\?\ everywhere, by adding a manifest. That's a good enough solution IMHO. At least it would solve 80% of the limitation possibly with 20% of the work.
