Projects / FastDup


FastDup is a tool to find identical files within directory trees, with a focus on the ability to scan very large trees and files in reasonable amounts of time. The use of clever techniques and optimizations to avoid comparisons allows fastdup to significantly outperform many existing solutions, and has a benefit of being entirely I/O bound (insignificant CPU usage). It is released under a modified BSD license, allowing all use, redistribution, and modification for non-commercial purposes.
