How to get drive type in Qt

[Hossein]

Hello everyone.
How can i get the list of all drives ( both removable and non-removable ) in my system and know which drive belongs to which drive type (as in removable or other drive types such as hdd, floppy disk etc ).
we have a simple class in C# called DriveInfo which gives a very detailed and easy to use methods for such tasks . I wonder if we have something like that in Qt.
Regards in advance

You have QDir::drives() and then winapi GetDriveType

Thank you but I am seeking a platform independent solution .

There's a class called QSystemStorageInfo in the Qt Mobility API.
You can use this as a base and extend it for other systems.

Qt doesn't have any other capability that does this, as far as I know.
There might be third party classes though.

found this thread and had the same problem (windows...)

Since Qt 5.4 you can use following:
http://doc.qt.io/qt-5/qstorageinfo.html#device

QByteArray QStorageInfo::device() const

Returns the device for this volume.
 
For example, on Unix filesystems (including OS X), this returns the devpath like [B]/dev/sda0[/B] for local storages. 
On Windows, it returns the UNC path starting with [B]\\\\?\\ [/B]for local storages (in other words, the volume GUID).

Returns the device for this volume.

For example, on Unix filesystems (including OS X), this returns the devpath like [B]/dev/sda0[/B] for local storages. 
On Windows, it returns the UNC path starting with [B]\\\\?\\ [/B]for local storages (in other words, the volume GUID).

For example:

bool bLocalDrive = false;
   QStorageInfo storage(qApp->applicationDirPath());
   /*
   storage.device() returns the device for this volume.
   For example, on Unix filesystems (including OS X), this returns the devpath like /dev/sda0 for local storages.
   On Windows, it returns the UNC path starting with \\\\?\\ for local storages (in other words, the volume GUID).
   */
   QByteArray qbaPath = storage.device();
#ifdef Q_OS_WIN
   if (qbaPath.startsWith("\\\\?\\")) 
      bLocalDrive = true;
#else
   if (qbaPath.startsWith("/dev/sda0")) 
      bLocalDrive = true;
#endif

bool bLocalDrive = false;
   QStorageInfo storage(qApp->applicationDirPath());
   /*
   storage.device() returns the device for this volume.
   For example, on Unix filesystems (including OS X), this returns the devpath like /dev/sda0 for local storages.
   On Windows, it returns the UNC path starting with \\\\?\\ for local storages (in other words, the volume GUID).
   */
   QByteArray qbaPath = storage.device();
#ifdef Q_OS_WIN
   if (qbaPath.startsWith("\\\\?\\")) 
      bLocalDrive = true;
#else
   if (qbaPath.startsWith("/dev/sda0")) 
      bLocalDrive = true;
#endif

Well, on Unix local devices can have more names than just "sda0"
"sda0" is "scsi/sata disk a, parition 0"

You will probably want to check for "/dev/" or use Solid
