How to disable Preview pane in File Explorer

To let the add-in work correctly, prevent Excel from crashing, & avoid other issues

The Preview pane in Windows Explorer is a headache for a lot of Excel users, but most of them don't even know about it. Excel may just quietly crash or warn that some workbooks are already open in another application, or work slowly, or refuse to run any add-ins. In general, nothing says that the cause of the problem is this pane.

One can find plenty of discussion on the Web about the troubles this pane causes starting from Office 2007. A bunch of bug reports has been sent to Microsoft, but the problem has not been solved. Thus, we recommend turning the Preview Pane off to avoid unpleasant surprises it may bring you.

Open File Explorer

Note. If you have numerous File Explorers opened, close all of them except for one.

There are several ways to open File Explorer:

  • Press Win + E on your keyboard.
  • Click the File Explorer icon on the taskbar (normally, it is in the bottom left corner near the Start button):
