# UnamDownloader 1.6.0 - A free silent downloader



A free silent (hidden) open-source downloader (binder) that can be built as a native C file or a managed (.NET C#) file. A downloader is essentially the same as a binder although it downloads the files instead of storing them in memory, you can also see my [UnamBinder](https://github.com/UnamSanctam/UnamBinder) for a normal file binder.



## Main Features



* Native or Managed - Builds the final executable as a native (C) or a managed (.NET C#) 32-bit file depending on choice

* Silent - Downloads and executes (if enabled) files without any visible output

* Tiny - Final downloader build is usually less than 5kb (depending on the amount of files to download)

* Multiple files - Supports downloading any amount of files

* Powershell - Does everything through powershell which currently greatly reduces detections

* Compatible - Supports all tested Windows versions (Windows 7 to Windows 11) and all file types

* Windows Defender exclusions - Can add exclusions into Windows Defender to ignore any detections from the downloaded files

* Icon/Assembly - Supports adding an Icon and/or Assembly Data to the built file

* Fake Error - Supports displaying a fake error message when file is originally started
