Kindle Disk Filler Utility

This utility helps fill up the storage space on your Kindle (or any device) to prevent automatic updates, especially useful for jailbreak preparation. It is available for Windows (PowerShell) and Linux/macOS (Bash).

Important: Copy the script (Filler.ps1 or Filler.sh) to the root directory of your Kindle when it is connected via USB. The root directory is the main folder you see when you open the Kindle drive on your computer (not inside any subfolder).

Usage

Windows (PowerShell)

Tip: To quickly open a PowerShell window in the correct folder:

• In File Explorer, navigate to the folder containing Filler.ps1.
• Hold Shift and right-click in the folder background, then select "Open PowerShell window here" or "Open command window here".
• Alternatively, click the address bar, type powershell, and press Enter.

1. Open PowerShell in the folder containing Filler.ps1.
2. If you get an execution policy error, you can bypass it by running:

   powershell -ExecutionPolicy Bypass -File .\Filler.ps1

   Or, for the current session only:

   Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
   .\Filler.ps1

3. Follow the on-screen prompts to select how much free space to leave.
4. The script will create files in the fill_disk folder until the desired free space remains.

Linux / macOS (Bash)

1. Open a terminal in the folder containing Filler.sh.
2. Make the script executable (if needed):

   chmod +x Filler.sh

3. Run the script:

   ./Filler.sh

4. Follow the on-screen prompts to select how much free space to leave.
5. The script will create files in the fill_disk folder until the desired free space remains.

Notes

• It is recommended to leave only 20-50 MB of free space to effectively block updates.
• To free up space again, simply delete the fill_disk folder after you have finished the jailbreak process.

After Jailbreak: Freeing Up Space

Once you have completed the jailbreak process, you can safely delete the fill_disk folder to recover storage space. You may also remove only some of the files if you want to keep the disk nearly full for a while longer.

• Windows:

  1. Open File Explorer and navigate to the folder containing fill_disk.
  2. Delete the fill_disk folder, or remove individual files inside it.

• Linux / macOS:

  1. Open a terminal in the folder containing fill_disk.
  2. Run:

     rm -rf fill_disk

     Or remove individual files as needed.

This will restore your available disk space.
