The QSystemStorageInfo class provides access to disk storage information from the system. More...
#include <QSystemStorageInfo>Inherits: QObject.
Note: All functions in this class are reentrant.
This class was introduced in Qt Mobility 1.1.

The QSystemStorageInfo class provides access to disk storage information from the system.
Note: Most functions in this class are reentrant on all platforms. The exceptions are listed below.
Note: In Symbian platform this class is not reentrant since Symbian Belle (Qt Mobility version 1.2).
Warning: On Symbian this class does not support QObject::moveToThread().
This enum describes the type of drive or volume
| Constant | Value | Description |
|---|---|---|
| QSystemStorageInfo::NoDrive | 0 | Drive type undetermined. |
| QSystemStorageInfo::InternalDrive | 1 | Is internal mass storage drive like a hard drive. |
| QSystemStorageInfo::RemovableDrive | 2 | Is a removable disk like MMC. |
| QSystemStorageInfo::RemoteDrive | 3 | Is a network drive. |
| QSystemStorageInfo::CdromDrive | 4 | Is a cd rom drive. |
| QSystemStorageInfo::InternalFlashDrive | 5 | Is an internal flash disk, or Phone Memory. Since 1.2 |
| QSystemStorageInfo::RamDrive | 6 | Is a virtual drive made in RAM memory. Since 1.2 |
This enum describes the state of the storage level of drive or volume.
| Constant | Value | Description |
|---|---|---|
| QSystemStorageInfo::UnknownStorageState | 0 | Storage level indicates an error, offline or unknown. |
| QSystemStorageInfo::NormalStorageState | 1 | Storage level indicates normal. |
| QSystemStorageInfo::LowStorageState | 2 | Storage level indicates below 40%. |
| QSystemStorageInfo::VeryLowStorageState | 3 | Storage level indicates below 10%. |
| QSystemStorageInfo::CriticalStorageState | 4 | Storage level indicates below 2%. |
This property holds the list of logical drives.
Returns a QStringList of drives or volumes, or an empty list if no drives are found.
Warning: On Symbian this function is not reentrant and must be used from main thread only.
Access functions:
| QStringList | logicalDrives () |
Notifier signal:
| void | logicalDriveChanged ( bool added, const QString & drive ) |
Constructs a QSystemStorageInfo with the given parent.
Destroys the QSystemStorageInfo object.
Returns the amount of available free space on the drive, in bytes.
Returns the storage state of the given drive.
This function was introduced in Qt Mobility 1.2.
This signal gets emitted when a new drive storage has been added or removed. If added is true, it means a new drive is found, otherwise a drive is removed.
This function was introduced in Qt Mobility 1.1.
This signal gets emitted when the storage state of a drive has changed to state. Note that the polling time may be different for different platforms.
This function was introduced in Qt Mobility 1.2.
Returns the amount of total space on the drive, in bytes.
Returns the type of the give drive.
Returns the URI, or unique identifier for the given drive.
This function was introduced in Qt Mobility 1.2.
