Activating the main menu item “View → Quick view panel” or the shortcut “Ctrl+Q” switches the quick view panel on/off. In the quick view panel the item highlighted in the active panel is shown separately.

How to view all files and/or (sub)folders within the current folder?
Activating the main menu item “View → Plain view – files” or the shortcut “Ctrl+B” activates the plain view for the active panel, or deactivates it. If “Plain view – files” is activated, only files (and no folders) are shown. The files of the main folder and of all sub folders are shown in one list, independent of their paths.
To view folders only, use the main menu item “View → Plain view – folders” or the shortcut “Shift+Ctrl+B”.
If you want to view all items – files and folders, use the main menu item “View → Plain view – files, folders” or the shortcut “Ctrl+Alt+B”.
While any plain view mode is active, the background color of the panel is highlighting. This can be defined in the tab “Color/font” of the main menu item “Tools → Settings → View → File/folder list”.
Attention: the display of the plain view could be slower than expected. It can be canceled with “ESC” key.

How to find empty folders?
To identify empty folders, go to Settings (F12) → View → Column profiles, create new profile, or edit existing one, and add the column “Items” to the profile, then restart FreeCommander.
You may need to change the file list panel width, or/and other columns width to see the “Items” column. You can drag the “Items” column left, if you want. Then click the “Items” column label, to view all emply folders on top.
If you want to find empty folders from all subfolders, or/and from different locations, you can use Plain view – folders (Shift+Ctrl+B), or File container, or even Search (Ctrl+F) and export the results to File container.
Note: 0 Byte(s) in the “Size” column doesn’t mean the folder is empty, it may contain folder(s) and/or file(s) with size 0 Bytes. When using the “Items” column, you don’t need to activate the “Size of folders” option and wait for calculating the folder size which may be slow.
How to redirect Win+E to FreeCommander?
In Windows the shortcut “Win+E” (with “Win” being the Windows key 
) opens the Windows-Explorer.
Activation of the FreeCommander menu item “Tools → Redirect “Win+E” to FreeCommander” redirects this shortcut, it opens the Windows-Explorer no longer, but opens FreeCommander.

.
After activating this menu item again the icon is no longer shown and “Win+E” opens the Windows-Explorer again.
This redirection requires the availability of the file “FCWinERedirect.exe” in the FreeCommander install folder.

FreeCommander is not responding when copying or moving the file(s), how to avoid it?
Do not perform too many operations at once.
Alternatively you can try the FreeCommander file operations and the Queue feature, this way only one operation is performed at the time, you can add the new operation(s) anytime, they will be added to the queue and performed in background, so you can use the FreeCommander during the operations.
The Queue feature is available only if the FreeCommander file operations are enabled, to do this, open the “Settings → File/folder operations → General” and set “Use FreeCommander” option for Copy and Move. You can also use the option “Make Queue button as default in the operation dialog” in “Settings → File/folder operations → Operations Queue”.
Note: FreeCommander file operations work only when using splitter bar Copy/Move buttons or F5/F6 hotkeys, they don’t work when using drag&drop, or Ctrl+C / Ctrl+X / Ctrl+V keyboard shortcuts.

I’m using the Column profiles or/and Automatic views, but I want to use different view sometimes, is it possible?
Yes, it’s possible, set view and columns you want and activate the “Lock view” feature in the main menu > View > Lock view (from release 811). The current view will be locked for all tabs and automatic views will be disabled, until it’s deactivated. This way you don’t have to switch view every time you change a folder or tab, or/and disable the Automatic views manually in Settings.
It’s possible to create a toolbar button and assign a keyboard shortcut for Lock view.
