I was wrong, indeed NAME_MAX is what should be used; looking at the code in KAutoSaveFile::open(), and how tempFileName() is actually used: tempFile = staleFilesDir + QChar::fromLatin1('/') + d->tempFileName(); NAME_MAX is what should be used, as tempFileName() returns the "filename" part only, not the whole path.
