I read another person was having the same difficulty back in August 2020, that I am now having, with regard to Vegas Pro 18 Suite semi-automatically installing the "Acoustic Mirror Impulse Files" into my Windows 10 "Documents" directory, as a default. Since this selection also required my mouse input (I had to click "OK"), I've ever since worried that I was supposed to pick a proper directory (I wish the instructions had made a comment on this required manual entry). I didn't learn enough from the August post to determine whether Vegas Pro can find these "Impulse" files all by itself, or whether I need to configure Vegas Pro so it sees the directory I created. I know Vegas Pro will function fine without knowing where the Impulse files are located, but I would rather Vegas Pro have full access, so hopefully I'll be able to start using the impulse files, rather than eventually discovering I needed to configure Vegas Pro if I ever wanted to access them. I believe these are "acoustic" files, but pretty much EVERYTHING about Vegas Pro is new to me, so they might be video files. I really need instructions targeted for a newcomer. I have a similar file-location question regarding two other plugins I will post in new threads.
