DriveInformation

class.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WinForms.Controls.ListControls

Details of one entry of a BinaryImageComboBox drive list: its path, volume label, display name and type, and the file-system limits Windows reports for it.

public class DriveInformation

Remarks

Passed to DriveSelectionChanged handlers. The values are read when the drive list is built, so they describe the drive at that moment.

The first entry of the list is the computer itself ("This PC"): its DrivePathString is empty and its numbers are 0. A drive with no medium, such as an empty card reader, has an empty volume label and zero numbers.
