FileSystemObject Object

One function of FileSystemObject object is the manipulation of general file system information. One type of the file system manipulation is related to the local system. The other type of the file system manipulation is related to the path string editing and the path string need not be an existing path.

Set FolderObjectName = FileSystemObjectName.GetSpecialFolder(folderspec)

 Or in JScript. Imply

FolderObjectName = FileSystemObjectName.GetSpecialFolder(folderspec)

Parameters:

FolderObjectName

The parameter "FolderObjectName" is the name assigned to the instance of the Folder object created by the method using the FileSystemObjectName.GetSpecialFolder Method.

FileSystemObject.Drives Collection

FileSystemObject.Drives Collection is used to return the collection of all Drive objects available on the file system of the local machine related to  the specified FileSystemObject Object.

Syntax:

FileSystemObjectName.Drives

 Or in VBScript. Imply

Set DrivesCollectionName = FileSystemObjectName.Drives

 Or in JScript. Imply

DrivesCollectionName = new Enumerator(FileSystemObjectName.Drives)

Parameters:

DrivesCollectionName

The parameter "DrivesCollectionName" is the name assigned to the instance of the Drives collection returned by the Collection Property using the FileSystemObjectName.Drives Property.

FileSystemObjectName

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

Return Values:

Drives collection

The property returns a Collection of all available Drive objects related to the specified FileSystemObject Object. 

Remarks:

FileSystemObjectName should always refer to a FileSystemObject Object.

Properties of Collection for VBScript:

Property Description
Count a read only property to return the number of items in the Drives collection.
Item to return an item corresponding to the specified key.

Methods of Enumerator for JScript:

Method Description
atEnd to check whether the enumerator is at the end of the collection
Item to return the current item of the Drive object in the enumerator of the Drives collection.
moveFirst> moveFirst to reset the location of current item in the enumerator of the collection to the first item in the enumerator of the collection
moveNext to move the location of current item in the enumerator of the collection to the next item in the enumerator of the collection

Remarks:

FileSystemObjectName should always refer to a FileSystemObject Object.

The term "Drive" under the FSO model can be a hard disk, a CD-Rom drive, a RAM disk or logically connected network Drive etc.

For removable-media drives, the media is not necessary to be inserted into the removable-media drives before these removable-media drives can be appeared in the Drives collection.

For JScript, the Collection is packed as an Enumerator at which Count property is not supported. And the supported properties are atEnd() method, item method, moveFirst method, and moveNext Method.

Examples:

  • Example of using the Drives property to return an collection of all "Drive" objects available

    ASP VBScript command:

    <script runat="server" language="VBScript">
    Dim fso, drivesc
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set drivesc = fso.Drives
    Response.Write drivesc.Count
    </script>
