How to show the drive size in QDirModel


From the Qt documentation: QDir Class Reference , QFileInfo Class Reference

use QDir::drives()

QFileInfoList QDir::drives () [static]

Returns a list of the root directories on this system.

qint64 QFileInfo::size () const

Returns the file size in bytes. If the file does not exist or cannot be fetched, 0 is returned.

How to use the same repo on external FAT drive on OSX and Windows?
The correct way to handle symlinks in git between multiple systems is to use it the way it was designed to be used, which is to have multiple clones and push and pull between them.
