删除Windows批处理中文件的最后一个换行符

Question

I have around 1340 * 2 GB files in recursive directories. I need to remove the last new line character (only once even if it has multiple new line characters) of every file if exists.
Since these are huge files, please let me know the way to delete the last new line character without reading entire file into memory, something similar to sed command sed '$ { /^$/ d}' *

Any help will be highly appreciated. Please see me as novice to batch and windows
