Methods CIM_DataFile has 14 methods:Ĭhanges the security permissions for the logical file specified in the object path. It is much faster than WMI, though, because it has considerably less overhead. This cmdlet has no remoting capabilities. Get-ChildItem is the equivalent of a built-in cmdlet to list files and folders. Learn more about accessing remote computers. Get-CimInstance -ClassName CIM_DataFile -Filter 'Name="c:\\windows\\explorer.exe"' -ComputerName webserver12 In contrast to Resolve-Path, Resolve-WmiPath comes with built-in remoting, so it can be used to resolve paths on remote machines as well: When specified, the function calls itself whenever it hits a subfolder.įunction Get-LogicalFile Here is an example of such a self-implemented recursion: Get-LogicalFile dumps the content of a folder and optionally supports a parameter -Recurse. This still takes much more execution time than using local commands such as Get-ChildItem, but it is faster than wildcard queries.
As pointed out already, in order to use wildcard queries, WMI always enumerates all files on your system first which is prohibitive.Ī more realistic approach is implementing the recursion yourself. Still, if you must use WMI to find files, the first step is not to use wildcard queries and the WMI operator LIKE. Once you want to search for a file across multiple folders, WMI becomes very slow. Classes like CIM_DataFile are extremely useful for accessing or testing the existence of individual files, or dumping the direct content of one folder. Searching Recursivelyįirst of all: WMI is not a perfect solution for recursive searches.
Powershell get file details windows#
# finding all files with extension that starts with L in Windows folder: Get-CimInstance -ClassName CIM_DataFile -Filter 'Drive="c:" and Path="\\windows\\" and Extension LIKE "l%"'īecause of this limitation, you cannot easily query multiple folders recursively in WMI.
