USB-mgr

USB-mgr is a simplified, lightweight alternative to Rufus, written in C#.

It writes the contents of an ISO image to a removable USB drive and is easier to use, smaller, and more beginner-friendly. Version 1.4 is built on .NET 8 and ships as a self-contained Windows executable — no .NET runtime required.

Features

• Write ISO files to USB drives (mount, copy, dismount — fully automated)
• Parallel file copying with live speed reporting
• Detects removable drives and the mounted ISO's drive letter automatically
• Simple and clean interface (WinForms)
• Localized UI: English, Russian, Georgian, Spanish, German, French (falls back to English)
• Lightweight

Safety notes

USB-mgr deletes all non-hidden, non-system files on the selected USB drive before copying. It asks for confirmation first, and it only ever considers removable drives. Double-check that you selected the correct drive before pressing Start.

Requirements

• Windows 10 or later
• .NET 8 SDK (build only); the prebuilt release is self-contained
