About 2 weeks ago I set out to locate SW that will do find & replace in unopened files.
Why the need? Because I am moving my site's files around (housekeeping) & want to be sure that all my internal links are updated accordingly.
For instance, suppose I have moved a page named "it.html" from a folder named "old" to a folder named "new"
Thus, I sought a program that could find every file on my site that contained the string...
And replace it with...
AND do it without my having to open the files.
I found it! "Alert Wildcard Search & Replace" is designed SPECIFICALLY for webmasters who want to do exactly this sort of thing...
*It allows use of wildcards.
*It allows verification of every change (or not, as you prefer)
*It displays each file where it finds the search string, & allows you either to replace it or to edit it or bypass it, etc.
*It automatically backs-up every changed page (if you tell it to)
*It will restore old pages (if you mess up)
*It gives you a list of changed pages, & details of the changes made thereto. It also will upload all changed pages to the server (if you tell it to)
*It also does META tag housekeeping (which I don't need, but it's there)
Installed, the 30-day trial version uses 1.93 of HD. I plan to buy it ($25) when my 30 days are up.
Take a look. It might suit your needs...
