MindGems
Windows software for finding duplicate files and photos, analyzing disk space, and file/PC
MindGems is an independently owned software company founded in 2001 that develops Windows desktop utilities for file management, duplicate detection, and disk space analysis. Its tools address the problem of redundant files and images, oversized folders, and cluttered storage by analyzing actual file content rather than relying only on names, sizes, dates, or checksums. The company reports more than 50 million users worldwide and offers seven products, including Duplicate Image Finder, Fast Duplicate File Finder, Folder Size, Audio Dedupe, Screen Capture & Annotate, Web Gallery Builder, and Boss Key.
Duplicate Image Finder compares visual content across more than 340 image formats, including RAW and PSD, and can detect edited, rotated, flipped, or color-corrected photos. It supports local drives, external HDDs, NAS, networks, and Adobe Lightroom Classic catalogs, with scan modes for visual similarity, exact matches, file size, EXIF date/time, and similar EXIF tags. Fast Duplicate File Finder compares binary data across any file format with integrated preview and network/NAS support. Folder Size lists largest files and folders with bar and pie charts and a Windows File Explorer context menu. Audio Dedupe uses acoustic analysis to identify duplicate songs across formats. Screen Capture & Annotate captures and annotates screenshots with callouts, arrows, and blur/highlight tools. Web Gallery Builder creates HTML image and video galleries with thumbnail conversion. Boss Key hides windows and can mute sound, change display resolution, and hide tray icons.
The products are packaged as Windows desktop applications for 32-bit and 64-bit systems, with scans conducted locally on the user's device. Some products are offered as free editions, while others are available as paid editions with a lifetime license; a free trial is available for Duplicate Image Finder.
