In my normal use of Dopus, I have the 'Miscellaneous | Explorer Replacement' preference set to 'Replace Explorer for all file system folders (recommended)'.
From time-to-time, it would be useful to be able to open a folder using Windows Explorer. I am sure there must be a very easy way to do this but it is eluding me at the moment.
Any suggestions on how to do this 
Open Explorer and find the file. 
I still have a shortcut to Exploder on my desktop, and use it only very rarely.
If you wanted to get insane with it, you could actually make an Opus button or context-menu item that was called "open in explorer" or something similar that pointed to the explorer program and passed the argument {f!}. That will cause explorer to open to whatever folder you had selected at the time.

This button will open an Explorer window showing the same folder as the current Opus window:
<?xml version="1.0"?>
<button display="both" effect="gray">
<guid>{A32A8065-581A-47C1-A36E-DAFC368B2C4E}</guid>
<label>Explorer...</label>
<icon1>114</icon1>
<function type="normal">
<instruction>Explorer /e, .</instruction>
</function>
</button>
If you want to launch a folder, say H:\Stuff, in Explorer without using Opus you can go to Start / Run and type:
explorer H:\Stuff
You can create a button or context menu entry that simply runs: Explorer.exe /E,"%1" if you want the folder tree enabled or Explorer.exe "%1" without the folder tree... This will load the selected/right-clicked folder into an Explorer window.
