How Do You Organise Your ScrapeBox URL Lists?

I'm still trying to figure out the best way of organizing my URL Lists.

So far its pretty basic.

I have the following files...

HARVESTED_WordPress.txt
HARVESTED_BlogEngine.txt
HARVESTED_Moveabletype.txt
HARVESTED_Captcha.txt

With the above files, I will save the raw harvested URLs, unsorted, unpageranked, unchecked.

And then after ive page ranked them, analyzed them to make sure they are open, I throw out the useless ones and save the good ones to master lists like this...

MASTER_Wordpress.txt
MASTER_BlogEngine.txt
MASTER_MoveableType.txt
MASTER_Captcha.txt

Once i build up enough, id like to start splitting lists by Page Rank.

How do you guys order yours?
Any ideas or ways i could improve would be welcome.

Thanks guys.

I like working with spreadsheet(excel or whatever you like)
also after each blast i'll check which one were auto-approve and separate it to an additional file.
whats taking most of my time is joining all the batchs(1mil result on each batch file)and removing duplicates domains/urls.wish there was a faster way of doing this

Crazyflx has a great post on removing dupes and working with HUGE files:
