The simple app for finding & managing duplicate files on your Mac. Singlemizer brings order out of chaos and frees up disk space. Files are compared on the basis of their contents only, not by names or dates or other possibly misleading attributes. This guarantees correct matching.
There are many applications which find duplicates using such indirect signs as similar filenames, equal creation dates and so on. In this case the probability of a false positives is very high and the consequences can be terrible. Singlemizer uses the industry-standard SHA-1 algorithm to compare files by their computed hash values. This guarantees that duplicate files are indeed duplicates.
Each location you choose to scan is assigned a priority. Duplicates found in each location are assigned the same priority as the location; when the scan is completed, the file with the highest value is designated as master file, i.e. it’s the original and all the others are copies. Simply put, priorities help to distinguish unwanted duplicates from valuable originals.
Singlemizer provides great flexibility in setting file selection parameters. For instance, you can choose which files types to include during the scan and manage other special options.
Unlike other duplicate-finding applications, you don’t need to wait for a scan to finish before being able to manage duplicates. Singlemizer’s report shows all duplicates of a particular file at the same time, allowing you to decide what to do with them, even while Singlemizer continues to search for more duplicates in the background. This can be a great time-saver if you are scanning folders of thousands of large files.
Sometimes we have duplicate files for reason. Imagine a situation when one particular file has to be present in couple of places simultaneously like some document or image copied in ~/Documents for keeping and in ~/Sites/MySite.com for sharing with friends. With Singlemizer you can save disk space occupied by such duplicates via replacing them with links to originals. All variants at your service: aliases, symlinks and even geeky hardlinks!
Singlemizer is capable of finding duplicate photos in the iPhoto Libraries. Just select some events you want to compare, start a scan and in a couple of moments Singlemizer will present a list of excess copies with thumbnails & other meta information.
