Does WinSCP Session.GetFiles check if file is finished uploading?

Question

I'm using WinSCP .NET assembly library to perform some SFTP operations - downloading files from SFTP location.

Do you know if method Session.GetFiles of the WinSCP library checks if file is not corrupted before downloading it - I mean the situation when someone uploads file to given folder and in the same time the WinSCP library wants to get files from this location?

How would it check if its corrupted, its just a binary file to it. — BugFinder, Mar 15 '16 at 11:43

No it does not. There's generally no way to test, if a file is being written to, over an SFTP protocol.

File locking is supported by few SFTP servers only. Notably it is not supported by the most widespread SFTP server, the OpenSSH.

What if I try to rename file before downloading and if I cant then it means that it is uploading? – Snorlax Mar 15 '16 at 13:28
On a typical *nix system you can rename a file while it is being written to. – Martin Prikryl Mar 15 '16 at 13:46
