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

The error occurs when trying to copy files "CTS%2FJJ%2FC50D530F4517%2F1%40tds.amadeus.com.wdseml" and "CTS%2FJJ%2FC50D530F4518%2F1%40tds.amadeus.com.wdseml". Comes the error message "scp: error: unexpected filename CTS/JJ/C50D530F4517/1%40tds.amadeus.com.wdsemll" and press the "OK" button WinSCP tries to copy and cancels with the error below.
Apparently the problem was because the characters "%2F" was resolved to "/".

I was uploading to an embedded device over a COM @ 115000 bps a folder with 400 files around 200/300 kByte. The first file that it was trying to upload it's named "12%2F8 Ballad.stg". This seems to be the problem. Uploading the single file lead to the explict error "scp: error: unexpected filename: 12/8 Ballad.stg" and no crash.

WinSCP kept disconnecting from the remote host - at first I thought this because the remote host was less responsive while doing RAID scrubbing but then on one retry effort I got this error message

@tvinde: Thanks for your report.

I am migrating files from my computer to my NAS. I tabbed in to find the error message; on checking where the file transfer stopped so I could resume it properly I found a missing .mp3 file from an album I was moving. The file was gone when I checked its location, on both source and destination systems, so I assume the file was horrifically broken in some manner and the OS realised when WinSCP was trying to move it. There are no other known issues in my source file system and the hard drive it was on has no known sector errors although I'm running a scan as I'm typing this and will update this issue report if there is one.
I do not expect a response or to be informed of a resolution to this and am only doing my due dilligence for your issue tracker.
