FileSystemObject Object

One function of FileSystemObject object is the manipulation of drives of the file system.

FileSystemObject.DriveExists

FileSystemObject.DriveExists method is the method to check whether the specified drive specification exist or not. The DriveExists method returns True if the specified drive exists and the DriveExists method returns False if the specified drive does not exist.

Syntax:

FileSystemObjectName.DriveExists(drivespec)

 Or in VBScript. Imply

driveflag = FileSystemObjectName.DriveExists(drivespec)

 Or in JScript. Imply

driveflag = FileSystemObjectName.DriveExists(drivespec)

Parameters:

driveflag

The parameter "driveflag" is the name assigned to the Boolean value returned by the method using the FileSystemObjectName.DriveExists Method.

FileSystemObjectName

The parameter "FileSystemObjectName" is used to specify the name of the instance of the FileSystemObject Object related to.

drivespec

The parameter "drivespec" is used to specify the drive to be checked. The value of parameter "folderspec" can be a drive letter or a completer drive specification.

Return Values:

Boolean value

The method returns a Boolean value to indicate whether the specified drive exist or not related to the specified FileSystemObject Object. 

Remarks:

FileSystemObjectName should always refer to a FileSystemObject Object.

For drive with removable media, the DriveExists method returns true even if there is no media present. And a removable media can use IsReady property of the Drive object to determine whether the drive is ready.

Examples:

  • Example of using the DriveExists method to check the existence of the specified drive

    ASP VBScript command:

    <script runat="server" language="VBScript">
    Dim fso, driveflag
    Set fso = CreateObject("Scripting.FileSystemObject")
    driveflag = fso.DriveExists("c:")
    Response.Write driveflag  & "<br>"
    Response.Write fso.DriveExists("c")  & "<br>"
    Response.Write fso.DriveExists("c:\")  & "<br>"
    </script>

    fso = new ActiveXObject("Scripting.FileSystemObject");
    driveflag = fso.DriveExists("c:");
    Response.Write(driveflag + "<br />");
    Response.Write(fso.DriveExists("c") + "<br />");
    Response.Write(fso.DriveExists("c:\\") + "<br />");

FileSystemObject.GetDriveName Method

FileSystemObject.GetDriveName method is the method to get the name of the drive string from the specified path specification related to the specified FileSystemObject Object.

Syntax:

FileSystemObjectName.GetDriveName(path)

 Or in VBScript. Imply

drvname = FileSystemObjectName.GetDriveName(path)

 Or in JScript. Imply

drvname = FileSystemObjectName.GetDriveName(path)

Parameters:

drvname

The parameter "drvname" is the name assigned to the drive name string returned by the method using the FileSystemObjectName.GetDriveName Method.

FileSystemObjectName

The parameter "FileSystemObjectName" is used to specify the name of the instance of the FileSystemObject Object related to.

Path

The parameter "Path" is used to specify the path specification for the component of which the drive name to be returned.

Return Values:

drvname string

The method returns a string of the  drive name related to the specified FileSystemObject Object. The GetDriveName method returns a zero-length string ("") if the drive can't be determined. The GetDriveName method only returns the drive name on the provided path string neither the conflict on the specified path nor the existence of the specified path will be checked.

Remarks:

FileSystemObjectName Method should always refer to a FileSystemObject Object.

Examples:

  • Example of using the GetDriveName method to return the drive name

    ASP VBScript command:

    <script runat="server" language="VBScript">
    Dim fso, drvname
    Set fso = CreateObject("Scripting.FileSystemObject")
    drvname = fso.GetDriveName("c:\test")
    Response.Write drvname & "<br />"
    Response.Write fso.GetDriveName("test") & "<br />"

FileSystemObject.GetDrive Method

FileSystemObject.GetDrive method is the method to return an instance of a Drive object corresponding to the specified drive specification related to the specified FileSystemObject Object.

Syntax:

FileSystemObjectName.GetDrive(drivespec)

 Or in VBScript. Imply

DriveObjectName = FileSystemObjectName.GetDrive(drivespec)

 Or in JScript. Imply

DriveObjectName = FileSystemObjectName.GetDrive(drivespec)

Parameters:

DriveObjectName

The parameter "DriveObjectName" is the name assigned to the Drive object returned by the method using the FileSystemObjectName.GetDrive Method.

FileSystemObjectName

The parameter "FileSystemObjectName" is used to specify the name of the instance of the FileSystemObject Object related to.

drivespec

The parameter "drivespec" is used to specify the drive specification for the Drive object to be returned. The parameter drivespec can be a drive letter (c), a drive letter with a colon appended (c:), a drive letter with a colon and path separator appended (c:\), or any network share specification (\\computera\share\). Unlike the return of drive name, an error occurs if the parameter drivespec does not conform to one of the accepted forms or does not exist. For network shares, a check is made to ensure that the share exists.

Return Values:

Drive object

The method returns an instance of Drive object corresponding to the specified drivespec related to the specified FileSystemObject Object. 

Remarks:

FileSystemObjectName should always refer to a FileSystemObject Object.

A normal path string for the drivespec of GetDrive method can be obtained by using a sequence of Methods on an existing path:

drivespec = fso.GetDriveName(fso.GetAbsolutePathName(path))

Examples:

  • Example of using the GetDrive method to return an instance of Drive object

    ASP VBScript command:

    <script runat="server" language="VBScript">
    Dim fso, DriveObjectName
    Set fso = CreateObject("Scripting.FileSystemObject")
    set DriveObjectName = fso.GetDrive("c")
    Response.Write DriveObjectName.DriveLetter & "<br />"
    set DriveObjectName = fso.GetDrive(fso.GetDriveName(fso.GetAbsolutePathName("test")))
    Response.Write DriveObjectName.DriveLetter & "<br />"
