The computer software supports both renaming operations on file contents but also on file names and supports the use of the two wildcards (*) and (?). The interface of the application is tab driven and the user is working from the left tab to the right to configure the renaming operations. Source files will be selected in the first tab. This can be done by typing them in, pasting them in or using a file browser that unfortunately cannot load the contents of directories into the application. Files can be excluded by dates.

The next tab defines the file replacements. It is possible to define multiple strings to be replaced in here. The options in the third tab contain several important settings like matching only whole words, enabling wildcard use, case sensitivity or limiting the replacements.

The fourth tab contains logging options. A record log will be written by default which will log all operations. This can be changed to disable logging or to log only positive or negative hits. The batch tab is the final tab which allows to execute batch files before or after the operation.

File Substring Replacement Utility is compatible with all editions of Windows including Windows XP and Windows Vista. It can be downloaded directly from the developer’s homepage.

Update: Program is Shareware. Possible free alternatives are TurboSR, String Find & Replace or Replace Text.
