DriveInfo class in .NET Framework is very useful class you can use to get information about the system drives. It has many properties and methods to query drive information such as drive type, drive format, total size or total free space. In the following Tutorial I will show you how to use this class in .NET Windows Application. Here is the list of the properties available in DriveInfo class.
|AvailableFreeSpace||Indicates the amount of available free space on a drive.|
|DriveFormat||Gets the name of the file system, such as NTFS or FAT32.|
|DriveType||Gets the drive type.|
|IsReady||Gets a value indicating whether a drive is ready.|
|Name||Gets the name of a drive.|
|RootDirectory||Gets the root directory of a drive.|
|TotalFreeSpace||Gets the total amount of free space available on a drive.|
|TotalSize||Gets the total size of storage space on a drive.|
|VolumeLabel||Gets or sets the volume label of a drive.|
Here is the code which you can use to access the properties of the driveInfo object. In the code below i have used the DriveInfo.GetDrives() function which will retrieves all logical drive names on a computer. You can use this information to iterate through the array and obtain information on the drives using other DriveInfo methods and properties. In the next statement the foreach loop is used to go through each object in the drive array. Then in the foreach loop if condition is place to check the IsReady property of the drive object. The indicates whether a drive is ready. For example, it indicates that a CD is in a CD drive or that a removable storage device is ready for read/write operations. If you do not test whether a drive is ready, and it is not ready, querying the drive using DriveInfo will raise an IOException.
The DriveFormat property has either NTFS or FAT32 value, The formatting of the drive. And here is the list of enumeration of driveType enum.
