Searching For and Removing Duplicate Files

One of the downsides of using multiple mobile Tablet PCs / UMPCs, is that inevitably duplicate files will creep up due to on-the-fly backups, trying different sync programs, etc. A GBM reader recently asked us for a recommendation on a program to search and remove duplicate files.

One of the programs I’ve used in the past is NoClone – It is fast, has lots of options, and is exhaustive. Here is a list of features from the product page:

• True Byte-by-byte comparison , not by CRC / MD5, totally safe to delete files.
• Search duplicate file contents regardless of file name
• Search duplicate pictures (jpg, gif), video (avi, mpg), songs(mp3), DLLs and any file types
• Search files with same contents, same name, zero size and truncated files.
• Simple fuzzy match
• Smart marker of duplicate files by date, version, size, folder and file name pattern
• Preview files, show file versions and properties
• Save search session / Export result list to CSV format
• Search local hard drives (Home ed.) and over network (Enterprise ed.)
