Every 70 seconds scrapebox inputs the good proxies into a file, any file I want, call it first.txt. So first.txt say has 5 lines of proxies. The 70 seconds later, it copies over the previous 5 proxie

This is a strange requirement.  What is the context/nature of the problem to be solved?

I want to copy the proxies from scrapebox that autmatically gets saved in a text file and proxies are replaced in same file after every 70 seconds, so i want to copy  the data and append it to a new file after every time data gets replaced in source file in every 70 seconds.

Sir, here is what i want.Every 70 seconds scrapebox inputs the good proxies into a file, any file I want, call it first.txt. So first.txt say has 5 lines of proxies.
The 70 seconds later, it copies over the previous 5 proxies and puts however many it found, say it was 10.
So first.txt has only 10 proxies, but the first 5 are gone.
So I wanted to copy those proxies every 70 seconds and add them to a second file and combine them with the first file.
So then I will have 15 proxies

Then it seems simpler to create an every minute scheduled task to do a copy (append).  No need for script coding required.

How can i create an every minute task to append the file?

Thanks, Bill
