There are several times when you may need to search and replace strings in multiple files, however doing so manually can be quite cumbersome, if the volume of files you have to replace is large.
A Freeware tool called Search & Replace Plus will allow users to replace strings in multiple files at once, you can select the directory and specify which types of files you want to change. Currently this software only supports a single mask type and the usage of wildcards is limited to the filenames itself, so you have to provide file mask in *.extensionname format, for example to replace strings in text files use *.txtusing *.* and *.tx* will not work.
If you are looking for a really simple utility to search and replace strings in files, this utility should fit your needs, however it does not support advanced functionalities.
