For those trying to bulk download their entire Kindle library using the BlueStacks K4A method, here's how to expand your BlueStacks instance from the standard 128 GB to 512 GB.
Note that all data will be wiped after execution:
1. Download BlueStacks Tweaker 6 from the "Download_2" link at the top (this app itself stopped development 2 years ago and doesn't work with the latest BlueStacks):
BlueStacks Tweaker - Official Site
2. After extracting the downloaded "BSTweaker69020.zip" file, extract the "Data_orig_vhd_512.zip" file from BSTweaker6\Drives to obtain the VHD image.
3. Convert VHD to VHDX. After completely closing BlueStacks, open a terminal with administrator privileges and use PowerShell's Convert-VHD cmdlet. You need to have Windows' Hyper-V enabled beforehand. Here's an example of running the cmdlet:
Code:
Convert-VHD -Path "%USERPROFILE%\Downloads\BSTweaker69020\BSTweaker6\Drives\Data_orig_vhd_512\Data.vhd" -DestinationPath "%ProgramData%\BlueStacks_nxt\Engine\Nougat64\Data.vhdx"
4. Start BlueStacks, launch the instance, and verify the results.
