I'm trying to extract a file from a disk image via drag-n-drop, with a program called IsoBuster, into a folder opened by DOpus, but I receive this message:
From the looks of it, IsoBuster tries to issue a command to copy *.* (a wildcard, meaning all files) from a temporary folder that is created on the fly, but it seems DOpus does not support that.
I've already talked to the developer of IsoBuster about this issue a while ago, and he basically said there's nothing he could do about it. And this works just fine in Explorer (always has), so I figure it should work with DOpus too.. right? I've tested both DO11 and DO12.
I've never seen what ISOBuster is doing documented in the API (which may just mean the information has been lost to time, or isn't included in the places I've seen), but if it works in Explorer then it should work in Opus, you're right.
