Now there is no need of saving each and every submission's source code you submit because a python script can do it for you and you just have to be relaxed.

Note: It will scrap your latest submission to a problem in case of multiple submissions.

Suppose the handle name is Jeet_Karia and directory where you want to save all your submissions is D:/Activities/Developer/Test Sample Input: python python scrap-cf-sub.py --handle Jeet_Karia --dir D:/Activities/Developer/Test

And in some moments submissions will be in your directory.

You can find the script here

Sample Output in my case:
