Topic review



Thank You for your help. we found the problem and it was not anything to do with WinSCP or .NET Assembly. After finally getting the server logs we found that the customer had started an extra copy of our transfer program on another machine and both programs were completing for the same files in the directory. That is why the files seemed to disappear and why where getting error in trying to access the files.

Once again thanks for your help.

Re: Files being delete when we have an error on GetFiles ?

There's no "delete" issued by WinSCP in the log. If the file disappeared from the server, it must have been deleted for other reason, and not by WinSCP. Maybe the file was actually deleted between LIST and SIZE already and that's why the download fails in the first place.

Files being delete when we have an error on GetFiles ?


I am using the .Net Interface to Pull files down from a server.

It basically work fine except when I get errors it seems to delete the File I am trying to Download and the other files in the directory ?

The Next Call does not contain the file that caused the error or the other files in the directory during the earlier call ?

I have attached the logs of the error and the code that I call it with.

This is my log of the error.
