12.6.3 beta: Can't double-click certain folders in particular zip files

I have a few custom rom files in zip format for my phones. Usually if I want to view the contents of the zip file I just double click on the zip file in the lister to list the files/folders within the zip and then double click any folder within the zip file to list the contents of that folder. However, I've come across what seems to be a strange bug - I'm assuming in Dopus. Within the zip file/folder structure are a number of folders named: install, org, google and com. Double clicking on these folders doesn't do anything. Right clicking on the folder name and selecting Open WILL open the folder. Other folders within the zip file will open when double clicking on them. I thought initially that this was because they were in lower case - other lowercase folders will open ok. The strange thing is, if I hover the mouse over one of the folders that won't open Opus will size it and also list its contents in the tooltip dialog. Very strange! One other thing, trying to rename these folders results in a file not found error from Opus.

Proof that we can actually list the "install" folder ONLY after right clicking the folder and selecting Open.


"com" and "org" folders won't open either unless using right click and Open

Sounds the same as:

I CAN open some folders by double clicking. Clicking on the folder META-INF in the first picture WILL open

I should just say i'm running opus version 12.6.3 beta.

@Leo I have these settings - none of which have been altered by me.

Thanks for the example zip/link. With that I can reproduce the problem.

The problem was introduced in the last beta (12.6.3) and is triggered by the zip file not having explicit entries inside it for any of its sub-folders. The sub-folders exist implicitly, due to files being below those paths.

For example, a zip file would normally have these entries:

  • :file_folder: META-INF
  • :file_folder: META-INF\com
  • :file_folder: META-INF\com\android
  • :page_facing_up: META-INF\com\android\metadata
  • :page_facing_up: META-INF\com\android\otacert

But this zip only has these entries:

  • :page_facing_up: META-INF\com\android\metadata
  • :page_facing_up: META-INF\com\android\otacert

That's unusual, but not strictly incorrect, so it isn't the zip file's fault.

It looks like 12.6.3 introduced a bug where you cannot double-click one of those implicitly-created folders if it only has other implicitly-created folders directly below it.

We'll get that fixed. We have fixed this for the next update.

Thanks for reporting it!

Ok, thanks for the update. I'd forgotten to mention that this didn't use to be a problem - doh!

12.7 with the fix is available now.
