An update. The OC developer added new options in v3.2.30.0. You can now configure QAPconnect with these values:
[One Commander v3]
;
https://onecommander.com/
AppPath=E:\Apps\OneCommander\OneCommander.exe
CommandLine=-o %Path% %NewTabSwitch%
NewTabSwitch=-newtab
You can add this section "[One Commander v3]" to your QAPconnect.ini file.
For future QAP releases, this configuration will be added in the QAPconnect.ini file for new installations. For existing installations, this new section will be available in the file QAPconnect-default.ini file (copy the new section to your live QAPconnect.ini)
