Hi Alex,

I am using the alex ftps client library in my application. I can set the connection but when I try to download a file I get this error: 

 "Access to path 'C:\' is denied"


Here is my code:


Dim client As FTPSClient = New FTPSClient()

client.Connect(server.Value, New NetworkCredential(user.Value, pass.Value), ESSLSupportMode.All, New Security.RemoteCertificateValidationCallback(AddressOf VerifyServerCertificate))

client.GetFile("/documentos/Enviados/Test.txt", "C:\\")


Best Regards.

did you check that you have permissions to create files / directories in c:\ ?

Thanks for the quick response. Yes I have permitions  to create files in c:\.

The error is returned by .Net's System.IO classes, so it's a permission issue. 


Your code is running in an application, a service or a web site, etc?

What is the user running the app in case?

UAC is enabled?

It's an application and my user is on the Administrator group of users.

The UAC is set to Never notify.


I tried to create a file with a  System.IO.StreamWriter:  


Dim SR As StreamWriter = New StreamWriter("C:\Test.txt", True, Text.Encoding.ASCII)

and there was no error.

In the mean wile I was trying to use the GetFiles function: 

client.GetFiles("/roff/Documentos/Exportados/", "C:\\", ??, EPatternStyle.Verbatim, True, ???)

 but I don't know how to set the filePattern and the AlexPilotti.FTPS.Client.FileTransferCallback. Can you send me an example please?

Best Regards,

I noticed that you are using "C:\\". That's the C# escape, in VB "C:\" is enough.

You can refer to the sources of the command line client as a sample fro GetFiles.

You don't need a transfer callback, unless you want to track transfer progress.

You might just use a Wildcard pattern specifying "*" or "*.*"

I tried "C:\" but I get the same error.

Now I'm trying the client.GetFiles("C:\", "*.*", EPatternStyle.Wildcard, True) and I get this error : "Unable to parse the directory list"!
