FARIF is a small VB6 utility that finds and replaces text within one or more files. As well as reporting the results of a search before replacement, it can also recursively search folders and has the option of case-sensitive searches.
Interesting tool!! Other than this, One of the interesting tools that I found recently is DuplicateFilesDeleter.It is tool that can be used to find & remove duplicate files.It is a simple to use,but very effective tool to locate duplicate files in one or more selected search paths.It scans the files and compares them based on Byte for Byte Comparison, which ensures 100% accuracy. You can then choose to delete the selected duplicate or original files. The program is multi-threaded which enhances the performance immensely & performs scans very quickly.Worth trying.
