List Large Files is a Free Portable USB Application that can be used to find the Largest Files in Windows. The tool works by using a GetFiles method to recursively search directories on a drive. It then compiles a string list of these files and sorts the resulting list by size.
Clicking a large file will bring you to its corresponding directory. From there you can decide what to do with the files. Additional features include the ability to specify which drive to search and the number of large files to display. Results can also be saved to a CSV file for Excel.
