It's not a common behaviour. You will have to ask that question to the server administrator.
Yes using .net assembly.
I just tested and tried fileZilla. Same thing happened. Is there any reason for that?
How programmatically? Also using WinSCP (.NET assembly)?
I've meant another SFTP client. For example OpenSSH
sftp or FileZilla.
I have tried to delete it using programmatically (C#).
Let me know if you have any other idea or other clients to delete.
Can you delete the files permanently using any other client using the same protocol?
I am using Winscp 5.9.4.
I opened the GUI of Winscp and deleted the file directly by right clicking and "Delete".
After sometimes (ranges from a few seconds to a few minutes), the deleted files reappears.
Tried to "clear cache", refreshes many times. Nothing works.
Let me know what I am missing.
Thanks in advance.
