So this method work over the internet? Or in tcp , ftp required server IP address?

hi , can someone tell me what's the best method for get file from another pc (legal way) ? see this video i attached here thanks ! have a good day Video_2024-03-26_172705.mp4

Hi , can someone help me to convert a python project in to Delphi code? Thanks !

Please take a look here is python project https://github.com/bkerler/edl And here is c project https://github.com/openpst/libopenpst

My budget is limited but I can invest 100$
