That being said, Capture One will work just fine as a file browser too.
David, you don't get the point - I am not browsing files in C1 at all - I am using some external program (which for me does the way better job for that purpose) and I just want to be able to start C1 with a raw file name as a parameter w/o a hassle to deal w/ sessions or catalogs, that's it...
why don't you (P1) just enable a mode (as an option - nobody takes anything away from catalogs/session loving folks) when C1 will create, whatever it wants to create, behind the scenes... it already can create a "CaptureOne" subfolder with cache, etc automatically - great, give us an option (again - just an option, nobody is taking anything away from those who needs sessions or catalogs) to automatically create some default session inside that folder w/o any UI dialogs bothering us when C1 is invoked that way and spare people who wants to use C1 just as a converter, not as a DAM, not as a browser, not as something else - but just as a raw converter, from unnecessary irritations...
take Adobe for example - LR is a big market, however there is a significant amount of people who do not use LR, but use ACR only... and Adobe caters to that populace as well... nobody is against P1s giving C1 "LR" features to compete against LR, but why at the same time you try to inflict a pain those who still wants to use C1 as "ACR" beats me...unless you intentionally trying to create your own captive user market vs LR (once people invest a great deal of time using your software as a DAM, etc they might be less likely to jump a ship no matter what migration options are offered by competition)... but then again you forget that there are "ACR" folks around - we are not going to use C1 as a DAM, so instead of capturing us you irritate us.
