Imagine that you are trying to find a certain file on your computer and you have five files with the same name and same size! Confusing, isn't it? What file do you really need? To avoid such problems and organize files you should remove unnecessary files. This saves hard disk space also. Duplicate Checker is a powerful tool for finding duplicate images, songs and any other file types. Main features: 1) search files with the same name, same size, same content (comparison of files uses CRC32 checksums); 2) image preview and thumbnails bars for pictures search; 3) many operations on list of found files - delete, move or copy. Duplicate Checker has many advantages compared with other such programs including its high-speed search process using an engine based on the STL technology, and a suitable interface which clearly separates file groups.
