Remove files (not directories) after GetFiles with WinSCP .NET assembly

Question

I'm trying to download files from a big tree of recursive directories, and I want the downloaded files to be removed after download. When I put true in remove parameter of GetFiles, it removes all the directories, but I want it to remove only the files and leave the directories empty. Is there any way to do it? Thank you.

Answer 1

Check the code of WinSCP extension Recursively move files in directory tree to/from SFTP/FTP server while preserving source directory structure.

Some alternatives:

• Do a regular download = do not set remove parameter of Session.GetFiles to true.
• Iterate TransferOperationResult.Transfers returned by the Session.GetFiles.
• For each successful download of a file, call Session.RemoveFiles.

A more complicated, but more efficient (if you have a large amount of files) approach would be:

• Replicate the directory structure in a remote temporary folder.
• Move all the files there, directory by directory, using Session.MoveFile. Despite the name, the method accepts wildcards.
• Download and delete the temporary tree at once using Session.GetFiles with remove set to true.
