If you want the second folder to stay updated with the potential changes that appear in the original folder after working with it, then yes, you would need to copy it again.
Oh, so that's how it is, okay, I hope this problem will be resolved quickly by BAS, even if there is a change in format, BAS can provide lessons so that the Fingerprint and Proxy settings can run well.
If I am running a script and one thread fails, the data used for it will disappear from the source and I cannot see which one has to be reused.
There is no way to know which data was taken, 'cause the thread had deleted all things used before. But u could log data used before the thread will be crashed.
