This part is about some basic information about Gemini duplicate finder, its main features, pros and cons.
Gemini 2 by the MacPaw Company helps users detect duplicate files on Mac and delete them easily. It is equipped with an intelligent algorithm that can accurately identify different types of duplicates including duplicate archives, audios, documents, images, videos and more. Gemini 2 offers a 3-day free trial that allows you to scan your Mac for duplicate files multiple times, but only cleans 500 MB data. To delete more unwanted duplicates and make your Mac duplicate-free, you need to buy its Pro version, which costs $19.95 per year.
Gemini doesn't just compare files on computer based on filenames. It also checks the contents of the files to make sure it finds exactly duplicate files. Sometimes we download the same file multiple times, but put in different locations. Gemini 2 can easily find them even they have different filenames or are hidden in different directories. What’s more, it can now identify files that look alike. Such as those photos taken from different angles.
Once Gemini duplicate finder finds duplicate files, it automatically and intelligently selects files, recommending which duplicates can be safely deleted. The tool compares file size, date, quality, and more to determine which files are redundant and which are important files you want to keep. This will save you more time than manually comparing and removing duplicate files one by one.
Gemini 2 offers a built-in file preview pane that allows you to conveniently view the file contents before removing duplicates. This is a very useful feature, as you can preview files to make sure you select the correct copy and don't accidentally delete important files. The preview pane supports multiple file types. You can preview images, play audios and videos, and even view document content.
Gemini duplicate finder has a real-time monitoring feature that helps you continuously monitor your system for new duplicate files. This means that no matter you add new files, download documents, etc. from other sources, Gemini will immediately start scanning and comparing, dealing with new duplicates in time. This way, you can keep the Mac computer clean at any time, and avoid the waste of storage space caused by duplicate file accumulation.
Overall, Gemini 2 is a powerful and easy-to-use tool that accurately finds duplicate files, and provides intelligent auto-selection and file preview feature. Some users also want to clean up redundant duplicates on Windows computer. However, Gemini duplicate finder Windows is currently unavailable. For Windows users, Cisdem Duplicate Finder can be the best alternative to Gemini 2.
