Replace In Files is a free software which makes search and replace operations on UTF-8 and Ansi files in the given folder and its subfolders.
Assume that, you have a lot of files in a folder. Some of them are encoded as Ansi, and some of them are encoded as UTF-8. You need to find and replace text in these files.
You don't want to pay for such a simple software. You need a free tool which supports Ansi and UTF-8, and does exactly what you want.
Yes, Replace in Files is what you're looking for!
Choose the folder your files are in, choose whether to search in subfolders, enter which types of files to search, enter the old text, enter the new text, and press Replace button. That's all!
