I have written an example script. See the link in my edited answer above.

Hi redlav, did you get it to work?

See https://winscp.net/eng/docs/script_download_files_to_same_folder

I have no idea how I could solve the problem with .NET.
Is there a code example where I could get my bearings?

No WinSCP cannot do this automatically.
Though scripting this in a PowerShell using WinSCP .NET assembly won't be that difficult.

Again, sync or plain copy (upload)?

Hi,

the transfer will take place in Sync mode. All changes should be applied to the target directory. In other words, no longer existing files in the source will be deleted from the target.

Thank you very much for your efforts.

Again, sync or plain copy (upload)?

Hello, I have coincidentally the same problem.

I have created a folder structure that is used for better overview.
Changes to files (change / delete / new) are to be synced in a single
directorie for further processing in this structure.

Sync or copy (upload)?

Is there a way I can sync a whole directory tree into one directory on the remote site?
