Folder Formats: Quick Guide [Opus 10 & 11]


This FAQ is for Opus 10 & 11. For other versions:

This FAQ explains how to make Opus use the same format in all normal directories.

There are two closely related FAQs which you may wish to read afterwards:

What is a folder format?

Folder Formats define things like the view mode (Details, List, Thumbnails, etc.), which columns are displayed (Name, Size, Type, etc.) and the sort order.

To define the format used for all directories:

  1. Open an Opus window, point it at C:\, and set it to use the view mode and columns that you want.

  2. Open the Folder Options window:


  3. From there, click Save and select For All Folders + Layouts & Folder Tabs.

    (Directory Opus Light: Choose For All Folders instead.)

  4. Choose Replace All when prompted.


Other settings you may need to change:

You may also wish to check these settings to ensure the default folder format is always the one which gets used:

  1. Go to Settings -> Preferences / Folders / Folder Behaviour and ensure Enable Folder Content Type detection is off.

    This ensures Opus will not change format automatically when certain types of files are detected.

  2. Go to Preferences / Launching Opus / Default Lister and ensure Ignore folder format of Default Lister is on.

    (Directory Opus Light: Skip this part as it does not apply.)

    This ensures you get the same format when opening a new window as you get when changing folders.

  3. Go to Preferences / Folders / Folder Formats and look at the items in the Default Formats category. Double-click the ones which are ticked and ensure they are set as you desire.

    You can also untick the Default Formats you don’t want to use, except the one called Custom which is what gets used whenever no other format is more applicable.

    (The Path Formats section of the list can also come into play, but should be empty if you have just followed the first part of the guide.)

    Click OK in the Preferences window to save your changes.

  4. If the Format Lock is on when you open a window then it can complicate things. You probably want to turn the Format Lock off, and then re-save the Default Lister, Layout or Style that you are using to open or configure the window.

    For normal behaviour, the lock icon on your status bar should be open, like this:


    The Default Lister is the most common way to open a new window. You can update it via:
    Settings > Set As Default Lister.

    (The Format Lock is not on by default. If a window opens with the lock on then it must be because you turned it on at some point and then saved over the Default Lister, Layout or Style you are using to open the window. If you need help working out what to change, please ask.)

Try your changes in a new window:

To test what you’ve done, close any open Opus windows, then open a new window and see if it is how you want it.

Always use a new window to check your folder format changes.
