My code removes 1kb files instead of 100 bytes. Why?

Question

cmd/bat

This cmd code deletes all files in the folder that are 1kb or less in size. With this, everything is in order.

But how to make sure that all files of 100 bytes and less are deleted ?

The code

@for /f %%i in ('set /a 1^^^<^^^<10') do @for %%j in ("{{папка с txt файлами}}\*.txt") do @if %%~zj leq %%i del "%%j"
