Meanwhile, just ignore calls to the Session.Failed, when you are calling the Session.FileExists. Just introduce some flag.
Using Session.FileExists() function throws "Session Failed" error
When I try to check if file exists at FTP site with Session.FileExists() function it fires up Session.Failed event when file is not there. The message is "Can't get attributes of file .... No such file or directory. Error code: 2. Error message from server: File not found."
Is there a way to void this message? I read documentation and found nothing about it.
