Singlemizer quickly and efficiently finds duplicate files on your computer and helps you remove them speedily and safely. It 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 100% correct matching.How many times have you imported images from your camera and forgotten to clean a memory card discovering non-topical photos to be imported once more? These duplicates not only spoil a nice hierarchical structure of your folders but also take a lot of space.All of us are afraid of losing our digital files. Therefore we make many backup copies using external hard disks, flash cards and network volumes. When files from different backups are mixed on your Mac to build their logical structure is practically impossible. You see several equal quarterly reports in one place then some of them elsewhere. Do they multiply?Downloads folder usually contains hundreds of unsorted files from the Internet. Applications, images, music, movies and documents are saved now and again without checking if they are already on your computer. You cant stop saving photos of fuzzy kittens repeatedly.FEATURES Simple interfaceSinglemizer displays only what you need to complete your task. Animation based on the iPhone Navigation Controller clearly shows what stage of the job you have reached. Scan anywhereSinglemizer scans files wherever they are: internal or external disks, flash cards, networked computers you name it.Searching Smart FoldersSinglemizer can scan Smart Folders just like any other folder. You can specify complex scans, such as all types of JPG with particular word in their names, created on a specified date and having a given label. Search location priorityEach location you choose to scan may be 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 priority is designated the master file, i.e. its the original and all the others are copies. File selection criteriaSinglemizer offers great flexibility in setting file selection parameters. For instance, you can choose files by type, files and folders by name, or files depending on both minimum and maximum size. Progressive resultsUnlike other duplicate-finding applications, you dont need to wait for a scan to finish before being able to delete duplicates. Singlemizers report shows all duplicates of a particular file at the same time, allowing you to decide whether to delete the duplicates or not, 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. Quick and accurateSinglemizer uses the industry-standard MD5 and SHA-1 algorithms to compare files by their computed hash values. This guarantees that duplicate files are indeed duplicates. Instant QuickLook previewNo need to launch an application to look at possibly duplicated files. All files in the report can be viewed using QuickLook, a great conveninece and time-saver. Customizing the duplicates reportYou can change what columns appear on the duplicates report icon, location, type, size, modified, hash value, priority and sort by most of them. Automatic or manual deletionYou can delete duplicates completely automatically, or for maximum control you can delete manually on a file by file basis. In both cases your original files are left untouched, and in fact with Singlemizer you cannot delete the master files anyway.
