🔍 Smart Duplicate Detection

downTidy detects duplicates using:

Fast FNV-1a 64-bit File Hashing (built-in C++)
Windows duplicate filename patterns:
- (1)
- (2)
- - Copy
- - Copy (1)

While your directory having multiple copy files, downTidy wipes out all the copy files and puts them in a separated file. And yes, you can delete them later anytime. Duplicate files are automatically moved into dedicated duplicate folders. Every Category having their own dedicated Duplicate folder.

📊 Cleanup Report

Every execution generates:

_downTidy.log

The report contains:

Date & Time
Files processed
Category statistics
Duplicate count
Error count

Logs are appended instead of overwritten. Newer logs can be found at the last of the file.
