CIM_DataFile class

The CIM_DataFile class represents a named collection of data or executable code. Only instances of files on local fixed disks will be returned.

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

Members

The CIM_DataFile class has these types of members:

• Methods
• Properties

Methods

The CIM_DataFile class has these methods.

Properties

The CIM_DataFile class has these properties.

AccessMask

Data type: uint32

Access type: Read-only

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

Windows 2000:  On FAT volumes, the FULL_ACCESS value is returned instead, which indicates no security has been set on the object.

Archive

Data type: boolean

Access type: Read-only

If True, the file is archived. This property is inherited from CIM_LogicalFile.

Caption

Data type: string

Access type: Read-only

Short textual description of the object. This property is inherited from CIM_ManagedSystemElement.

Compressed

Data type: boolean

Access type: Read-only

If True, the file is compressed. This property is inherited from CIM_LogicalFile.

CompressionMethod

Data type: string

Access type: Read-only

Free-form string that identifies the algorithm or tool used to compress the logical file. If the compression scheme is unknown or not described, use "Unknown". If the logical file is compressed, but the compression scheme is unknown or not disclosed, use "Compressed". If the logical file is not compressed, use "Not Compressed". This property is inherited from CIM_LogicalFile.

CreationClassName

Data type: string

Access type: Read-only

Name of the class. This property is inherited from CIM_LogicalFile.

CreationDate

Data type: datetime

Access type: Read-only

Date when the file was created. This property is inherited from CIM_LogicalFile.

CSCreationClassName

Data type: string

Access type: Read-only

Class of the computer system. This property is inherited from CIM_LogicalFile.

CSName

Data type: string

Access type: Read-only

Name of the computer system. This property is inherited from CIM_LogicalFile.

Description

Data type: string

Access type: Read-only

Textual description of the object. This property is inherited from CIM_ManagedSystemElement.

Drive

Data type: string

Access type: Read-only

Drive letter (including the colon that follows the drive letter) of the file. This property is inherited from CIM_LogicalFile.

Example: "c:"

EightDotThreeFileName

Data type: string

Access type: Read-only

DOS-compatible file name for the file. This property is inherited from CIM_LogicalFile.

Example: "c:\progra~1"

Encrypted

Data type: boolean

Access type: Read-only

If True, the file is encrypted. This property is inherited from CIM_LogicalFile.

EncryptionMethod

Data type: string

Access type: Read-only

Free-form string that identifies the algorithm or tool used to encrypt a logical file. If the encryption scheme is not indulged (for security reasons, for example), use "Unknown". If the file is encrypted, but either its encryption scheme is unknown or not disclosed, use "Encrypted". If the logical file is not encrypted, use "Not Encrypted". This property is inherited from CIM_LogicalFile.

Extension

Data type: string

Access type: Read-only

File name extension without the preceding period (dot). This property is inherited from CIM_LogicalFile.

Examples: "txt", "mof", "mdb"

FileName

Data type: string

Access type: Read-only

File name without the file name extension. This property is inherited from CIM_LogicalFile.

Example: "MyDataFile"

FileSize

Data type: uint64

Access type: Read-only

File size, in bytes. This property is inherited from CIM_LogicalFile.

For more information about using uint64 values in scripts, see Scripting in WMI.

FileType

Data type: string

Access type: Read-only

File type using the Extension property. This property is inherited from CIM_LogicalFile.

FSCreationClassName

Data type: string

Access type: Read-only

File system class. This property is inherited from CIM_LogicalFile.

FSName

Data type: string

Access type: Read-only

File system name. This property is inherited from CIM_LogicalFile.

Hidden

Data type: boolean

Access type: Read-only

If True, the file is hidden. This property is inherited from CIM_LogicalFile.

InstallDate

Data type: datetime

Access type: Read-only

Date and time the object is installed. This property does not need a value to indicate that the object is installed. This property is inherited from CIM_ManagedSystemElement.

InUseCount

Data type: uint64

Access type: Read-only

Number of "file opens" that are currently active against the file. This property is inherited from CIM_LogicalFile.

For more information about using uint64 values in scripts, see Scripting in WMI.

LastAccessed

Data type: datetime

Access type: Read-only

Date and time that the file was last accessed. This property is inherited from CIM_LogicalFile.

LastModified

Data type: datetime

Access type: Read-only

Date and time that the file was last modified. This property is inherited from CIM_LogicalFile.

Manufacturer

Access type: Read-only

Manufacturer string from the version resource (if one is present).

Name

Data type: string

Access type: Read-only

Inherited name that is the key of a logical file instance within a file system (provide full path names). This property is inherited from CIM_ManagedSystemElement.

Example: "c:\winnt\system\win.ini"

Path

Data type: string

Access type: Read-only

Path of the file including the leading and trailing backslashes. This property is inherited from CIM_LogicalFile.

Version

Data type: string

Access type: Read-only

Version string from the version resource (if one is present).

Writeable

Data type: boolean

Access type: Read-only

If True, the file can be written. This property is inherited from CIM_LogicalFile.

Remarks

The CIM_DataFile class is derived from CIM_LogicalFile.

WMI implements the CIM_DataFile class and all of its methods. The CIM_DataFile class is a dynamic class.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
