Need VB script to do a mass change of files

I want a vb script that can help me do a mass change of files.

the script must do the subsequent:

1. prompt for file extension or use the " * " option for searching all files.

2. prompt for the word to find in the files.

3. prompt for the word to change from the word shows in step 2.

4.. search all files and make a .csv file to list of the items found and have separate columns for the filename and the word it was searching for.

3. prompt to review the .csv file and select yes/no to commit the changes.

4. Get the files prior to committing the changes. (prefer it to capture the whole directory/file same to how tarball captures the directory structure for the archived files)

5. make a .csv file showing the changes made.

Please place comments in the vbscript for the .csv filename so it can be simply changed.

Skills required are Script Install, Windows Server
