Thank You. That looks like it might be what I need. If not, it may help get me there.

I will test it as soon as I can. I am having problems with Qt Creator. I just updated to 9.0.0 and now Qt Creator crashes/closes as soon as I try to go to the designer.

I just posted this issue.

@SimonSchroeder
QDir is only for directories, not for files. So it is not a (suitable) candidate for general "file paths".

@Pardeep said in Japanese letters in file path converted into question mark(?). How can i deal with them?:

qDebug()

This is simply debug output, it can depend on the encoding in the console. Try

qDebug()<<fileName1.toUtf8()<<"\nExist: "<<f1.exists();
