There doesn't seem to be a path cvar set up for it, so your only option is to symlink the folder, or more specifically use a directory junction in this case as it's windows, and you want to use a different physical drive.

open file explorer and then copy into the address bar exactly -

%AppData%\..\Roaming\wolfcamql\wolfcam-ql
<hit enter>

Move the "videos" folder to where you want it to be, I'm going to use d:\videos as the example.
Or you can rename it you just can't have a 'videos' folder by that name existing at this location for the link command to work.

Then open up a console window (cmd.exe ) and enter

mklink /D /J %AppData%\..\Roaming\wolfcamql\wolfcam-ql\videos d:\videos

Change the path at the end if you put the videos folder elsewhere, the first path in the command must point to a non-existing folder as stated above, it will fail if 'videos' already exists, the second path must point to the existing folder that you wish to link to.

Ahh, thanks a lot. So far, I've been filling up the drive all my programs except my OS and games are on, then transferring it 150GB at a time onto my storage drive

If you don't mind it moving the cache, configs etc too you can change fs_homepath as brugal mentioned elsewhere, I was just thinking about videos specifically.

I just stopped being lazy, and now I'm only rendering the parts I want. I hate doing that, cus I'd rather scrub through in a video editor than sit through all the junk, but the files are big enough to cause issues with that anyways, so I'll just deal with the bad transport controls, and just skip the 90% where I'm dead

use d3dgear and set the format to avi2 which can go over 2GB limit of avi

gets on your whatever, because it will record all monitors, even if the others are not being used
