Win32_Directory class

  • Artikkel

The Win32_Directory WMI class represents a directory entry on a computer system running Windows. A directory is a type of file that logically groups data files and provides path information for the grouped files. Example: C:\TEMP. Win32_Directory does not include directories of network drives.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties

The Win32_Directory class has these properties.

AccessMask

Data type: uint32

Access type: Read-only

Qualifiers: Schema ("Win32"), DisplayName ("Access Rights")

Bitmask that represents the access rights required to access or perform specific operations on the directory. For bit values, see File and Directory Access Rights Constants.

Note

On FAT volumes, the FULL_ACCESS value is returned instead, which indicates no security has been set on the object.

This property is inherited from CIM_LogicalFile.

FILE_READ_DATA (file) or FILE_LIST_DIRECTORY (directory) (1)

Grants the right to read data from the file. For a directory, this value grants the right to list the contents of the directory.

FILE_WRITE_DATA (file) or FILE_ADD_FILE (directory) (2)

Grants the right to write data to the file. For a directory, this value grants the right to create a file in the directory.

FILE_APPEND_DATA (file) or FILE_ADD_SUBDIRECTORY (4)

Grants the right to append data to the file. For a directory, this value grants the right to create a subdirectory.

FILE_READ_EA (8)

Grants the right to read extended attributes.

FILE_WRITE_EA (16)

Grants the right to write extended attributes.

FILE_EXECUTE (file) or FILE_TRAVERSE (directory) (32)

Grants the right to execute a file. For a directory, the directory can be traversed.

FILE_DELETE_CHILD (directory) (64)

Grants the right to delete a directory and all of the files it contains (its children), even if the files are read-only.

FILE_READ_ATTRIBUTES (128)

Grants the right to read file attributes.

FILE_WRITE_ATTRIBUTES (256)

Grants the right to change file attributes.

DELETE (65536)

Grants delete access.

Grants read access to the security descriptor and owner.

WRITE_DAC (262144)

Grants write access to the discretionary ACL.

WRITE_OWNER (524288)

Synchronizes access and allows a process to wait for an object to enter the signaled state.

ACCESS_SYSTEM_SECURITY (18809343)

Controls the ability to get or set the SACL in an object's security descriptor.

Archive

Data type: boolean

Access type: Read-only

Qualifiers: Schema ("Win32"), DisplayName ("Should Be Archived")

Indicates whether the archive bit on the folder has been set. The archive bit is used by backup programs to identify files that should be backed up. If True, the file should be archived.

Remarks

Overview

Folders are file system objects designed to contain other file system objects. This does not mean that all folders are alike, however. Instead, folders can vary considerably. Some folders are operating system folders, which generally should not be modified by a script. Some folders are read-only, which means that users can access the contents of that folder but cannot add to, delete from, or modify those contents. Some folders are compressed for optimal storage, while others are hidden and not visible to users.

WMI uses the Win32_Directory class to manage folders. Significantly, the properties and methods available in this class are identical to the properties and methods available in the CIM_DataFile class, the class used to manage files. This means that after you have learned how to manage folders using WMI, you will, without any extra work, also know how to manage files.

The Win32_Subdirectory association class is also used to manage files and folders. The Win32_Subdirectory class relates a folder and its immediate subfolders. For example, in the folder structure C:\Scripts\Logs, Logs is a subfolder of Scripts, and Scripts is a subfolder of the root folder C:\. However, Logs is not considered a subfolder of C:\.

You can retrieve the properties of any folder in the file system using the Win32_Directory class. The properties available using this class are shown in Table 11.1. To retrieve the properties for a single folder, construct a Windows Query Language (WQL) query for the Win32_Directory class, making sure that you include the name of the folder. For example, this query binds to the folder D:\Archive:

Copy "SELECT * FROM Win32_Directory WHERE Name = 'D:\\Archive'"

When specifying a file or folder name in a WQL query, be sure you use two backslashes (\\) to separate path components.

If you want to limit data retrieval to a single disk drive, include a Where clause specifying the drive letter. For example, this query returns a list of all the folders on drive C:

"SELECT * FROM Win32_Directory WHERE Drive = 'C:'"

If you need to enumerate all the folders on a computer, be aware that this query can take an extended time to complete.

Examples

The following VBScript sample retrieves properties for the folder C:\Scripts.

strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFolders = objWMIService.ExecQuery("SELECT * FROM Win32_Directory WHERE Name = 'c:\\Scripts'")
For Each objFolder in colFolders
 Wscript.Echo "Archive: " & objFolder.Archive
 Wscript.Echo "Caption: " & objFolder.Caption
 Wscript.Echo "Compressed: " & objFolder.Compressed
 Wscript.Echo "Compression method: " & objFolder.CompressionMethod
 Wscript.Echo "Creation date: " & objFolder.CreationDate
 Wscript.Echo "Encrypted: " & objFolder.Encrypted
 Wscript.Echo "Encryption method: " & objFolder.EncryptionMethod
 Wscript.Echo "Hidden: " & objFolder.Hidden
 Wscript.Echo "In use count: " & objFolder.InUseCount
 Wscript.Echo "Last accessed: " & objFolder.LastAccessed
 Wscript.Echo "Last modified: " & objFolder.LastModified
 Wscript.Echo "Name: " & objFolder.Name
 Wscript.Echo "Path: " & objFolder.Path
 Wscript.Echo "Readable: " & objFolder.Readable
 Wscript.Echo "System: " & objFolder.System
 Wscript.Echo "Writeable: " & objFolder.Writeable
Next

The following VBScript sample returns a list of all the hidden folders on a computer.

strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("SELECT * FROM Win32_Directory WHERE Hidden = True")
For Each objFile in colFiles
 Wscript.Echo objFile.Name
Next
