Drive numbers and letters.
A drive may be represented by either an integer between zero and twenty five inclusive, or by a buffer descriptor containing a character between "A" and "Z" inclusive, followed by a colon. This class encapsulates both representations. An instance of this class is constructed specifying either the drive number or the drive letter and may be converted between the two representations.

| aDrive | The drive number. |
| Panic Codes | |

| IMPORT_C | TDriveUnit | ( | const TDesC & | aDrive | ) |
| Parameters | |
|---|---|
| aDrive | A descriptor containing text whose first character is the drive letter. Can be upper or lower case. Trailing text is ignored. |
| Panic Codes | |
|---|---|
| FSCLIENT | 1 if the drive letter is invalid, i.e. does not correspond to a drive number. |
| IMPORT_C TDriveName | Name | ( | ) | const |
Gets the drive unit as text.
The drive letter is returned with a trailing colon.

| FSCLIENT | 0 if |
| IMPORT_C TDriveUnit & | operator= | ( | TInt | aDrive | ) |
| Parameters | |
|---|---|
| aDrive | The new drive number. |
| Panic Codes | |

| FSCLIENT | 0 if aDrive is greater than or equal to KMaxDrives. |
| IMPORT_C TDriveUnit & | operator= | ( | const TDesC & | aDrive | ) |
Assigns a drive letter to the drive unit.
The letter must be between A and Z or a panic is raised. Any trailing text within the descriptor is ignored.
