I have a question now : if I have a resource file with a size of 234m, but I want the file to be 510m (521719b), how should I add "garbage characters"

[ouroborosscr]

Oh, I can. The first line is the file size, change it to the target size, and then add garbage characters

[ouroborosscr]

The question now is: how to reduce the 2000m file to 510m...
