Mass Search and Replace Tool

Mass Search and Replace Tool is a tiny and portable software program that enables you to search for text within multiple files at the same time and replace it with something else.
It enables you to apply search filters in order to narrow down results, such as regular expressions and wildcards. The app is rather intuitive, even for less experienced users.
Since there is no installation involved, you can drop the .exe file in any part of the hard disk and just click it to launch Mass Search and Replace Tool. Otherwise, you can save it to a pen drive or other removable storage unit to directly run it on any PC with minimum effort and no previous installers. Plus, it doesn't modify Windows registry settings, unlike most installers.

Indicate the scan scope and apply search filters

Based on a large window that provides direct access to all available options, the interface is easy to navigate. You can begin by selecting a directory whose files you want to include in the scan scope, with or without subfolders.
It's possible to use regular expressions or wild cards, ignore the case, as well as to filter the files by type. Once you perform a search, Mass Search and Replace Tool shows results in the bottom part of the screen, allowing you to enter new text to replace the old one with. This operation doesn't take long. There are no other notable options available here.

Thanks to its intuitive interface and options, Mass Search and Replace Tool should come in handy to all users who want to easily search and replace text across multiple files simultaneously.
