+#+title: Emacs
+
+Emacs' built in file manager Dired is often used to browse files. And Emacs is often used in WSL on Windows, because the windows-native GNU Emacs is kind of meh.
+But sadly some typical files we have to deal with on windows are files Emacs can't handle very well. (Mostly MS Office files)
+
+To use Emacs' Dired in WSL Emacs to open files in Windows, the ~wslview~ command from Wslutilities can be used.
+
+Put this in init.el:
+#+begin_src emacs-lisp
+(defun my/wslview-open(&optional @fname)
+  "Use wslview to open file in Windows."
+  (interactive)
+  (let* (
+         ($file-list
+          (if @fname
+              (progn (list @fname))
+            (if (string-equal major-mode "dired-mode")
+                (dired-get-marked-files)
+              (list (buffer-file-name)))))
+         ($do-it-p (if (<= (length $file-list) 5)
+                       t
+                     (y-or-n-p "Open more than 5 files? "))))
+    (when $do-it-p
+        (mapc
+         (lambda ($fpath)
+           (shell-command
+            (concat "wslview " (shell-quote-argument $fpath))))  $file-list)
+        (when (not (string-equal major-mode "dired-mode"))
+            (revert-buffer)))))
+#+end_src
+
+Now, when you mark files in Dired using ~m~ (or if nothing is marked, the file under point is used) run ~M-x my/wslview-open~ to open the marked files using whatever is the appropriate program in Windows.
+If more then five files where marked, Emacs will prompt in the minibuffer if that many files should really be opened.
+Also, if you are not in a Dired buffer and you run ~M-x my/wslview-open~, the file of the currently open buffer will be opened with the appropriate program in Windows.
