Filename changes incorrectly in the File location field when creating Virtual Hard Disk

[rocket_]

Hello, VirtualBox 6.1.2 r135662 (Qt5.6.2) under Windows 10 (1909) host. When creating new Virtual Hard Disk for virtual machine, there are path and filename set by default in File location field. Drive:\path\filename.vdi. If you click Hard disk file type radio button(s), the extension of the filename in File location field does not change, as expected; instead of that it appends to the old extension, every time you click on different file type radiobuttons (VHD, HDD, etc). Please see attached screenshot for understanding clearly.

Create Virtual Hard Disk window

[Antonio López Fernández]

It would be extremely easy to solve this problem:

File: src/VBox/Frontends/VirtualBox/src/wizards/newvd/UIWizardNewVDPageExpert.cpp
Line: 215
Change: fileInfo.completeBaseName() instead of fileInfo.fileName()

if (fileInfo.completeSuffix() != m_strDefaultExtension)
{
    QString strNewFilePath = QString("%1/%2.%3").arg(fileInfo.absoluteDir().absolutePath()).arg(fileInfo.completeBaseName()).arg(m_strDefaultExtension);
    m_pLocationEditor->setText(strNewFilePath);
}
