PC Froze at the end of a very big (700 GB) ftp session

[Barry Marshall]

I have an old NAS (Netgear Stora - 2010) which required flash to run, but I accessed it via the sftp and started to transfer the files, to my QNAP NAS, about 105,000 files I recall. The logs were all working, about 4,500 files did not transfer because of permission restrictions I think. I watched the queue progress OK. I think it finished but then just stopped. I could not close the app. I was able to alt-tab to other software and close that, but I could not use the PC (Windows 10). I had to power cycle the PC.
Everything seems OK now.
I would like to have seen the log files saved then I would know if it really completed. Also an option to continue if the queue was interrupted.
PS: I just noticed a notification message that "All transfers have finished. 45,871 could not be transferred"
Many Thanks
