The Software Duplication Detector (SolidSDD) is a standalone application for detecting and managing source code duplication (i.e., code clones) in software. It can be used to analyze large projects and detect code that has been cloned (e.g., via cut-n-paste operations) during development. The currently supported programming languages are C, C++, C# and Java. In addition to identifying the code clone fragments, SolidSDD offers an intuitive graphical interface for assessing the code duplication characteristics and the location of the duplicated fragments in the code stack. This interface enables developers, architects and software managers to better manage the process of refactoring by assessing the required effort and establishing refactoring priorities.
