Sound familiar?
File chaos affects everyone. FileSight is built to solve these specific problems.
“My Downloads folder is a mess.”
The Download Organization Assistant automatically categorizes files into Documents, Images, Videos, Audio, Archives, Applications, and Code.
“I accidentally saved five copies.”
Duplicate Finder 2.0 uses SHA-256 hashing, similarity analysis, and confidence scoring to identify exact and near-duplicate files.
“I don’t know what’s taking space.”
Smart folder scanning shows you storage usage at a glance, grouped by file type, size, and location.
“I waste time searching for files.”
Fast local scanning indexes your files instantly. Preview panel lets you inspect content without opening separate apps.
“I can’t preview files quickly.”
Built-in preview panel supports images, PDFs, video, audio, and text files. No need to launch multiple applications.
Everything you need to manage your files
Powerful tools that work together to help you understand, organize, and clean your files.

Smart Folder Scanning
Intelligently scan entire volumes or specific folders with filtering and exclusion rules.
How duplicate detection works
Multi-layered analysis minimizes false positives and gives you confidence in every cleanup.
Folder
Select any folder or drive to scan
Group by Size
Files are grouped by exact byte size for initial matching
Hash Files
Each file gets a unique SHA-256 fingerprint
Compare SHA-256
Hashes are compared to find exact duplicates
Similarity Analysis
Filename and extension similarity are analyzed for near-matches
Confidence Score
Each match gets a confidence score based on multiple signals
Suggested File to Keep
The best copy is suggested based on location, date, and name
Why this approach minimizes false positives
- Size-grouping eliminates obviously different files before hashing
- SHA-256 guarantees cryptographic certainty for exact matches
- Filename similarity catches renamed duplicates traditional tools miss
- Extension-aware matching prevents false matches between different file types
- Confidence scoring lets you decide what threshold to use
