Help regarding changing DOWNLOAD_DIR path

[askfriends]

I want to change default download location of the files in VPS, so how can i change DOWNLOAD_DIR = "/usr/src/app/downloads" to some other path or folder?
I have 240gb ssd and another 2tb hddisk, now all files go to ssd so i want change it to 2tb hardsk.
Can you write couple of dummy folder paths so it will give me some idea.

and btw that VAR mentioned above is responsible for that or there is something else?
