Summary: You may need to make some filetype changes to get RAR, 7z, ISO, etc. archives to open in Opus.
[ul][li]Directory Opus 10 and above:
Directory Opus supports opening Zip, RAR, 7z, ISO, Tar.Gz and several other archive formats as if they were folders.
For Zip archives, everything you need (including whether double-clicking Zips opens them in Opus) is configured under Preferences / Zip & Other Archives / Zip Files.
Support for the other (non-Zip) archive formats can be turned on and off via Preferences / Zip & Other Archives / Archive and VFS Plugins. When enabled, those formats will automatically open in Opus when double-clicked in Opus. However, you will need to make some filetype adjustments if you also want those formats to open in Opus when double-clicked in other programs (e.g. archives that you open from the desktop, or from a web-browser or download manager).
The example below uses the RAR filetype, but the same instructions apply to 7z, ISO, GZ, etc.
Note about ISO files:
[ul][li]The built-in support for ISO files opens them like archives and not as mounted drives.
If you open an ISO via Opus it will not have a drive letter and will not be visible to other programs. If you send files to other programs then, as with normal archive formats, Opus will extract the files to a temporary folder and tell the other programs to open the temporary copies.
Consequently, trying to install software off an ISO in this way will usually not work (unless you extract everything out of the ISO first), since the setup.exe on a CD or DVD usually expects to find the other files that accompany it. You can configure Opus to auto-extract the entire archive when a .exe is double-clicked, but that probably does not make sense for something the size of an ISO.
Use Opus’s built-in ISO support if you just want to browse inside an ISO and copy some files out of it. On the other hand, if you want to install software from an ISO, mount it using something like VirtualCloneDrive (which is free and works great with Opus), Daemon Tools, or the ISO-mounting support in Windows 8.[/li][/ul]
Example: Make RAR files open in Opus 10 when double-clicked in other programs
[ol][li]Find the RAR file type
Go to Settings -> File Types and expand the System File Types section of the list.
Scroll through the list (or type “RAR”) to see if there is already a RAR file type.
If you find the RAR file type in your list, double-click it and skip the next step.
[li]Create a new RAR file type
You should only do this step if you don’t already have a RAR file type.
Click on the New
button and then select New File Type
from the menu which appears.
Define an icon for the new type. If you want to re-use Opus’s Zip file icon then click Change Icon
, point to C:\Program Files\GPSoftware\Directory Opus\dopus.exe
and then pick the appropriate icon.
Give the file type a description such as "RAR Compressed File"
Type “.rar” into the extensions field.
[li]Opening RARs from outside of Opus
Go to the Actions
tab and select open
from the list. If there is an existing definition click Delete
to erase it, then click Edit
The type should be left as the default (“Run an application”) and the application should be set to:
This will mean that when you double-click a RAR file on your desktop, or from a program such as a download manager, it will be opened in a new Opus window.
Alternatively, if you want RAR files to open in new tabs rather than new windows then use this line instead:
(Or, if you want the existing window to be reused without opening a new window or tab, don’t specify ‘new’ or ‘newtab=findexisting’ at all.)
Once you have defined your open action make sure it is selected and then click Set Default to ensure it is used when opening RAR files.
[li]Directory Opus 9 and below.
Earlier versions of Opus only support Zip and RAR.
Zip is configured via Preferences (similar to Opus 10).
For RAR, the same filetype changes are needed as for Opus 10 to make RAR files open in Opus when double-clicked in other programs.
Additionally, Opus 9 also requires a filetype change to make RAR files open when double-clicked within Opus:
Opening RARs within Opus (Opus 8 & 9 only):
Do not do this if you are using Directory Opus 10. The newer version automatically adds .RAR to the Archives file type group, which already has the required double-click setting.
[ul][li]Follow the steps in the guide above for Opus 10, and keep the RAR filetype open.
[li]In the filetype editor, go to the Events tab and edit the Left double-click event. This event only applies inside of Opus and overrides what happens when you double-click RAR files. If it is left empty then the open action will be run instead, which you probably don’t want if you just made it open new windows or tabs.
Set the event to run the go command. This will mean that when you double-click a RAR file within Opus it will open in the current window as if you had double-clicked on a real folder.
In the screenshot below you can see that some of the other events also have commands set. These are optional but can be quite useful. For example, I have defined Left double-click + Shift to open RARs in a new window and Middle double-click to open them in a new tab in the second file display.
