MULTI USB CLONER 2000 ▀ BATCH / POWERSHELL CREATION

2025-04-30

This script collects all MP4 video files located in D:\Videos [including subfolders],
that where created or modified today and copies them to all connected flash drives.

3,4,5 flash drives? Software doesn’t care about the number of connected sticks.

Before copying it creates two lists in the Temp system folder: matching files and available flash drives.
When the copy is complete, it beeps through the speakers via standard WAV and displays the GUI report window.

Application can be potentially useful where mass replication occurs.
Built around plain batch script with some PowerShell injections and yeah it is Windows 7 compatible.
