I am doing a File Content Comparison between my local files and an FTP server and FFS will reliably get killed by Windows and Linux after a few minutes. Please fix this 😭

Screenshot show memory usage at 16GB and climbing!

_x86_x64, does that mean it is a 32-bit process?
Are you able to run the 64-bit version?

If so, does that work without OOM?

I just installed the Linux version at https://freefilesync.org/download.php so whatever that installs is what I am running.
