CIM_LogicalFile class

  • Άρθρο

The CIM_LogicalFile class represents a named collection of data, which can be executable code, that is located in a file system on a storage extent.

Important

The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

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.

Bitmask that represents the access rights required to access or perform specific operations on the file. 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.

"Pred Fail" indicates that an element is functioning properly, but is predicting a failure (for example, a SMART-enabled hard disk drive).

Non-operational status can include "Error", "Starting", "Stopping", and "Service". "Service" can apply during disk mirror-resilvering, reloading a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither "OK" nor in one of the other states.

This property is inherited from CIM_ManagedSystemElement.
