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.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

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.

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).

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.

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 know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

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.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

@ffreitas2: 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.

<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.
