Multiple File Manager is a straightforward option for batch renaming and deleting of files.
No complicated interface to work with here. Multiple File Renamer gives you a direct approach to performing renaming and deletion of files. It is presented from a simple UI that features a dropdown for the included actions. To keep it simple, Multiple File Manager does leave out the ability to see if any of the user-selected changes took place through the interface, so to verify the selected action completed, you will need to check via File Explorer. Files can be selected without the need for any key combo. Once you have the files selected, you can choose your option from the dropdown menu and then press Go.
Multiple File Manager is designed to be a simple option for file management without the need for overly complex options.
