Explorer.exe

Command-line switches that you can use to open the GUI Windows Explorer (Explorer.exe).

Syntax
      Explorer.exe options

Options
    /n            Open a new single-pane window for the default selection. This is usually the root
                  of the drive Windows is installed on. If the window is already open, a duplicate opens.

    /e            Open Windows Explorer in its default view. This is usually the users home drive.

  (,)/root,object Open the specified object in a window view.

   /select,object Open a window view with the specified folder, file or application selected.

   /separate      Launch an explorer instance as a separate process (undocumented option).

Quotation marks are required if the File/Folder object contains spaces or symbols.

If /e or /n are followed by a comma and folder path then explorer will open and display the folder, the /e or /n have no effect, this provides backwards compatibility with older versions of Windows. If the object is given as a filename rather than a folder, the file will be opened using the default application, like START.

Explorer.exe is normally found in the Windows folder, typically C:\Windows\Explorer.exe

Current versions of Windows no longer allow the use of variables such as %username% in a shortcut target executable, but you can pass a variable as a parameter to Explorer.exe making it possible to build shortcuts which open explorer at a given path. A kind of poor mans folder redirection.

Windows File Explorer search box

Windows File explorer supports Advanced Query Syntax (AQS) to help define precise searches.
Microsoft describe this as an 'obsolete technology' but it is still present and mostly working. Searches work for filenames and properties but not reliably for file contents, use a third party tool for that.

File kind to search	AQS Keyword	Example
All file kinds	everything	kind:everything
Author	author or by	author:"Gabrielle Zavin"
Company	company	company:Microsoft
Date	date	date:today date:tomorrow date:yesterday date:this week date:last week date:next month date:past month date:coming year
Date modified	datemodified or modified	modified:last week
Deleted	deleted or isdeleted	isdeleted:true
Documents	docs	kind:docs
Favorites	favorites	kind:favorites
File extension	ext or fileext	ext:.txt
File name or foldername	Filename or name	filename:MyResume filename:*Resume
File name or foldername (exact match)	Filename or name	filename:=MyResume
Files within a specific folder or any subfolders	folder, under or path	folder:downloads folder:"Public\Public Desktop"
Files within a specific folder name	foldername or in	foldername:mydocs or in:mydocs
Folders	folders	kind:folders
Music	music	kind:music
Pictures	pics	kind:pics
Presentations	presentations	kind:presentations
Programs	programs	kind:programs
Size	size	size:> 5m
Spreadsheets	spreadsheets	kind:spreadsheets
Status	status	status:complete
Text documents	text	kind:text
Title	title, subject or about	title:"Quarterly Financial"
Videos	videos	kind:videos

There are additional keywords available but many will only work for specific document types (e.g. datelastprinted: lastsavedby).

You can combine search keywords and file properties with the following operators to broaden or narrow a search.

Operator	Example	Result
NOT	social NOT security	Finds items that contain social, but not security.
Space	social security	Finds items that contain social and security.
OR	social OR security	Finds items that contain social or security.
Quotation marks	"social security"	Finds items that contain the exact phrase social security. Use quotes to match "long filenames".
Parentheses	(social security)	Finds items that contain social and security in any order.
>	date:>11/13/2023 size:>500	Finds items newer than a given date (use the locale’s date format). Finds items with a size greater than 500 bytes.
<	date:<11/13/2023 size:<50k	Finds items older than a given date (use the locale’s date format). Finds items with a size less than 50 Kbytes.
..	date:11/13/21..11/15/21	Finds items with a modified date between the given range (use the locale’s date format).

The operators NOT and OR must be in uppercase and can’t be combined in the same query.

Similar search options are provided in macOS Finder but with a graphical interface.
