File page similar to directory page in mui2?
I wonder if there is a ready-to-use file page just like mui2's directory page but accepting files instead of directories (possibly plus a file extension list). I would implement it using nsDialogs but I think the problem is so common that there are probably several solutions already. Maybe I just didn't use the right search terms to find them?

nope - it's also not all that common in an installer; last I've seen one was for a multi-thousand dollar program that let the user download big fat maintenance update files -or- point to such a file locally (e.g. if provided by the reseller on a separate disc).

But, as you mentioned, it's fairly simple to whip one up yourself with nsDialogs - can just take the template page one for the directory out of the NSIS\Contrib\ModernUI...something folder and adjust that, even :)

Ok, I'm now in the process of implementing my own, hope I can post some results soon

So here it is, layout equals the mui2 directory page. Comments welcome, e.g. on my use of some uniquely created ID to enable multiple use of the page (probably there is a better way?), or how to make the groupbox text useable in multiple languages, ideas for providing "save"-version as well, or JUST GENERALLY NOT GOOD STYLE comments are welcome ;-)

Ok, I've put it to http://nsis.pastebin.com/sAtyhgTY
But I can't edit my original post anymore. I'll keep it in mind for future posts.
