So the following command would affect only files, not directories:ĭetect whether a path points to a file or a directory by reading the Extended Attribute for 'Directory' (as listed below). It does not actually set the attribute on the folder itself.Ī directory, you must explicitly specify the directory name you cannot use The Read-only attribute of a folder can be set or cleared in Windows Explorer as a fast method of setting/clearing the Read-only attribute of all files within the folder. The Name of a folder can be changed but that is a rename operation not an edit of the contents. This is because unlike a file, a folder object does not contain any content that can be edited. The Read-only attribute (R) does not apply to a folder. You can display or change some attributes for a directory/folder. You can use wildcards (? and *) with the pathname parameter to display or change the attributes for a group of files. If a file has the System or Hidden attribute set, you must clear that attribute before you can change any other attributes with ATTRIB. If a file has both the Hidden and System attributes set, you can clear both attributes only with a single ATTRIB command.įor example, to clear the Hidden and System attributes for the RECORD.TXT file, type: Hidden and System attributes take priority. In older versions of Windows, Explorer would display 'p' to indicate a 'sparse' file. Used with just the /S option ATTRIB will quickly search If no attribute is specified attrib will return the current attribute settings. The numeric values can be used when changing attributes with VBS/WSH P Pinned Attribute (Windows 10) This refers to the "Always available on this device" setting for OneDrive files. N Normal (0: cannot be used for file selection) L : Work on the attributes of the symbolic link versus the target of the Symbolic link. S : Search the pathname including all subfolders. # Note: Assumes that no indices higher than 1000 exist. Here's code that finds the indices of all supported property names: $folder = (New-Object -ComObject Shell.Application).NameSpace("$pwd") Note that all property values are returned as strings, and that if the targeted property is not filled in, the empty string ( '') is returned try 0 (the file's name) as a standard property to verify that the call works in principle. $folder.ParseName((Split-Path -Leaf $file)), # Output the value of the "Comments" property. $folder = (New-Object -ComObject Shell.Application).NameSpace((Split-Path $file)) Reading document properties programmatically: $file = 'C:\path\to\some\file.doc' Note that interactively, modifying - but not adding - properties via the Properties dialog in File Explorer may be possible, if a File Explorer extension is installed for a given document type (such as for Microsoft Word *.docx files). Otherwise, you must use an application-specific API, such as the various COM libraries for Microsoft Office applications e.g., New-Object -ComObject Word.Application this documentation may provide further information. NET API does exist, although updating properties requires workarounds: see An example of a fork that still appears to be maintained is this repo.įor image files, specifically, a standard. Note that many variations of these packages ( Microsoft.WindowsAPICodePack.*) exist in the NuGet gallery, with many forks of earlier, seemingly abandoned packages. NET wrappers around Windows APIs may offer a solution, as demonstrated in this C# answer. Unofficial 3rd-party NuGet packages that are. Judging by this forum thread, you can only read such extended document properties via the Windows (GUI) shell (the Shell.Application COM API) - see next section.įor updating (editing) properties via.
