Joerg Rosenthal

About

Joerg Rosenthal is a developer based in Germany, primarily known for the creation of Anti-Twin, a small, lightweight software application designed for efficient file management. Anti-Twin, which was developed to compare files and search for duplicate or similar files on hard disk drives, offers a comprehensive set of features including bit-by-bit and fuzzy comparisons for both file content and names, alongside advanced image comparison with preview capabilities. The software, operating under a Free Personal Proprietary license, allows users to directly manage found files by sending them to the recycle bin or deleting them. Although the product was discontinued in 2010, it remains available from the developer and is still functional on Windows 11, supporting multiple languages and working offline. While specific revenue figures, leadership titles beyond Joerg Rosenthal as the implied developer, and a precise founding year for the operation are not available, the nature of the product suggests a very small team, likely 1-10 employees. No specific market position or competitors are detailed, but its longevity and continued availability highlight its unique appeal as a robust, no-registration-required utility.
