This is a fantastic editor for Mac OS or for anyone who needs to edit entire groups of files.
I had been hard coding the IP addresses into a suite of web pages I author for my church. Of course every time my ISP changed my static IP address to a new one, I'd have to edit all of the pages individually and do a separate search and replace function. Now I have several hundred sermons online, all of the pages that point to the sermons and the .m3u audio index files that each point to a separate unique audio file, and each of these files had the hardcoded static IP address for my cable modem embedded in the file. Thousands of files, right!
Then I found out about DYNDNS.org and listed my cable modem's IP address with them at my dyndns address. That meant I needed to replace the IP addresses with the new URL for the church website, which again meant doing search and replace operations on thousands of files. A real headache right?!
Enter Alphatk. Alphatk has a feature I've never seen before even on Winblows Word XP! Alphatk lets you find and run a global search and replace for a string through an entire filesystem hierarchy like a folder or an entire hard disk and replace things like "220.127.116.11" with "cornerstone.dnsalias.org" and it instantly opens each file in the hierarchy and replaces every instance of the dotted IP with the URL! In about 13 seconds, Alphatk did this replacement for me in over 2000 files!!!!
It would have taken me about 15 or 16 hours to do this manually!!!
Well worth downloading and purchasing!
