You'd need to re-export Opus to the new stick. To keep the old settings, copy the folder from the old stick to the new one, then tell Opus to export over the top of itself (like you would when updating the version on the USB stick). Opus will ask if you want to export the program and keep the existing settings, or if you want to overwrite the settings as well.
Now, when I start Dopus on the target laptop from the old stick (which was upgraded instead of the new stick), Dopus starts with a fresh configuration instead of my previous configuration.
I have already repeated the installation, this time onto the new stick, but this installation also starts fresh and not with my configuration.
How is this possible, and can I still restore my previous configuration?
This shouldn't matter, but as portable path I use I:\Dopus instead of I:\portable.
Which folders would I have to look out for? If I look the folders up that are mentioned here:
...it seems that this simply is the entire portable installation folder. That doesn't seem to be correct?
If the “use as a dongle” option is selected, as in your screenshot, then the files can be exported to any location, and it’ll probably remember the last one you used for convenience.
Just tell it to export to the place you want the files when you get to that stage in the process.
Oops, I just realized that I had copied the portable installation folder on the laptop from the stick to the hard drive and started it from there, using the stick only as a dongle.
Now that I have started Dopus from the hard drive again, my configuration is back.
Afterwards, however, the entire configuration on the USB stick seems to have been overwritten.
I was not asked whether I wanted to keep, or overwrite the existing settings.
Is this expected behavior, as it doesn't seem to match your instructions above? In the end it is not a problem as I have backed up the previous configuration. However, I thought it should be clarified.
Edit: I just now realized that this happened because I had changed the path in the export dialog, which is why the export went to the G:\Dopus\Dopus directory instead of the G:\Dopus directory of the previous installation. After I had reset the path, everything worked and the expected prompt also appeared before the export:
The only difference between my Dopus installation on the PC and the portable version on the laptop are the tab groups of the default dual lister that I always use. I have tried to restore the tab group for the laptop by transferring my "ThinkPad Tabs.otg" file from the v12 configuration to the v13 configuration (after overwriting the complete laptop configuration with the PC configuration for other reasons).
However, this somehow did not seem to suffice to define my default double lister for the laptop, including the two tab groups in "ThinkPad Tabs.otg". Which settings file(s) do have to be transferred additionally, in order to transfer my default dual lister including the left and right tab groups?
"ThinkPad Tabs.otg" and "default.oll" doesn't seem to be sufficient. With this, while I get my default [dual] Lister, the correct default tab sets in both left and right Listers are not opened.
Not sure what it's called officially, but it is the (dual) Lister that Dopus opens with per default when starting up, which also is the only Lister that I use.
What opens at startup depends on Preferences / Launching Opus / Startup.
(Assuming we're talking about starting Windows. If not, it may be one of the other pages under the same category.)
Also check that /dopusdata resolves to the config directory you're modifying. If it doesn't, you may still be running Opus from your main HDD install, not the USB stick. (If it's already running, running it again from the USB stick will just tell the existing instance to open a new window, not switch over to the USB stick. You'd need to use File > Exit Directory Opus to switch.)
I have recreated my standard tabs now. I suspect that for some reason I had overwritten the config file "ThinkPad Tabs.otg" with an older version. This seems to have been the reason my standard tab set was not displayed.
