Comparing two text files and save difference

Is there a way to compare two text files?

For instance if I have one text file for urls to visit and another for urls already visited , is there a way to compare if the first file has urls from the second list, and if so scrub that list to a new text file?

Example:

urls_visited.txt contains:

url1.com

url2.com

url3.com

and

Urls_not_vitisted.txt contains:

url1.com

url5.com

url4.com

Result Needed: (Scrubbed)

Urls_To_Follow.txt contains:

url5.com

url4.com

I wrote my example:

Compare2Files

When you start you need to specify the path to the two files (urls_visited.txt and Urls_not_vitisted.txt) in the format of "path/file.txt"

After completion of work, you can use the values in the table variable Urls_to_follow to continue the code. Or keep the table values to a file using Good End - Return Variable.

I do not understand how to keep the entire table with the Write File because there is no way to save the entire table. You can save only a certain line.

You can simply save each checked line using Write File - Wrap And Append.

But I prefer to add the results to the table - you're all the same will to use them in the module.
