Simple upload question.

This question I am asking may have been asked many times before, but I guess its a simple one.

When is it safe to remove a USB stick when uploading a large number of ROMs? I.e. If I can see and access a ROM, is that ROM fully installed and not half-finished? Because the retropie almost instantly upload a large amount of content (20 GB) from the USB drive.

If the stick doesn't have a visual indicator for activity (led blinking when it's active), then you can check the list of processes currently running on the Pi and check for rsync. Once there is no more rsync process running, then the transfer has completed.

These two commands can tell you if rsync is running:

pgrep rsync
pidof rsync

Enter either of them in RetroPie's command console that you'll end up in by pressing F4 in Emulation Station. If there is an output of one or more numbers (the process IDs), rsync is still running. If there's no output, it's not.

Exit the console by entering exit.

Thank you both.
