External exception C0000029 - System::Sysutils::RaiseLastOSError

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
Just doing a bundle of file transfers at the same time (i.e. a whole directory) and getting a load of errors when I do so. It's properly tedious.
<If relevant, consider attaching a session log file or a screenshot)>

WinSCP 6.1.2

Doing a large download of files from my linux host to a windows platform, hit the red X during the download process to cancel. Instead of a nice cancel, it throws this exception.

I had selected a folder to copy down from a linux host to my windows system. WinSCP was calculating the size of the folder. I noticed that the source contained loads of stuff I didn't want to copy and clicked the red X to cancel it. The calculating window disappeared and the download window opened, and started the download process. Again I clicked the red X to cancel the process (maybe twice clicked). the tool paused and threw the External Exception C0000029 error.

Re: External exception C0000029 - System::Sysutils::RaiseLastOSError

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

External exception C0000029 - System::Sysutils::RaiseLastOSError

Thanks for sending me the debug version and replying so quickly. Without checking the link on how to use the debug version I got my settings to connect and tried to synchronise the folder I still need fully copied. I picked direction as local and got the network error and the exception below just as before. I'll check the debug link next to see what I may have missed. I read somewhere it may be because I'm copying to a mirrored drive (networked too).

External exception C0000029 - System::Sysutils::RaiseLastOSError

Trying to copy data from two main programs which were run online via Hosted Desktop. I copied the smaller folders and subfolders by drag and drop but the largest is having problems with interruptions every 2 minutes with network error - cannot copy file. I originally did drag n drop but it never finished so now I am using synchronise. The target is a NAS with a mirroring RAID drive arra. The file copy error occurs frequently but this C00000029 seems new, though I think it will occur again.
