You can just QString dot = ".", but you should use a single character instead of a string, since it's just a single character

Without the fromStdString() I get the following compilation error.

src/core/batchrenamejob.cpp:64:15: error: 'QString::QString(const char*)' is private within this context

QString dot= ".";

I must admit I don't fully understand the compilation error however adding fromStdString seemed the most reasonable way to fix it.

Please use QStringLiteral() instead.

I wonder if just getting rid of .toLower() fixes this bug

I agree with @abalaji here. Modifying the code around this line should fix the bug and also address my previous comment.

I tested just removing the .toLower() however this didn't fix it. It seems that QMimeDatabase::suffixForFileName() converts it to lower case unless I overlooked something. See the code snippet below.

I tested this with the following lines in a standalone program:
QMimeDatabase db;
QUrl url = (QString) "foo.TXT";
const QString extension = db.suffixForFileName(url.toDisplayString());
qDebug(qUtf8Printable(extension)); //Outputs "txt"

Rather than using contains here, you can just use lastIndexOf, check if it's not -1, and go from there. Just simply urlStr.lastIndexOf('.').

I think you can use QUrl::filename(), and you should do it from the calling code.

Just making sure I understand you correctly.
Are you saying I should change the function to take the filename as a QString and extract the filename from the QUrl outside of the function or change url.toDisplayString() to url.fileName() within the function?

Function/method names are usually lowercase. Also, we don't add get for getters, only set for setters.

⇒ fileExtension() ?

Additionally, we pass QString via reference

⇒ QString &filename ?
