You can add a symbolic link to the original folder to the local folder and access the symbolic link of the folder. If the folder name includes blank, be sure to use parentheses on the path. EX) jav-it.exe catalog -d "<your_video_path>"
You can add a symbolic link using mklink.
mklink /d "local path" "your video path"
Personally, I use synology NAS and I store all my JAV there. I had my NAS connected to my HDD as Z drive.
I symbolic-linked my JAV folder to my local C drive as "mklink /d c:\nasjav z:\jav"
After setting the link, jav-it has been working flawlessly for me.
