That is because this file is actually not present in Nepomuk. All you
have is a resource with an identifier "Password.txt".
This happens if you do the following:
Nepomuk::Resource res("Password.txt");
since there is no relation between the string and a file.
Using
Nepomuk::Resource res(KUrl(QFileInfo("Password.txt").absolutePath()));
would be a safe bet in case there is a file "Password.txt" in the
current folder.
You have to keep in mind that KUrl does not automatically resolve
relative paths. Your application needs to take care of that.
Cheers,
Sebastian
