Get hard drive size of SFTP server

I am using Renci.SshNet (SSH.NET) library to upload files on SFTP server. Before uploading a file I want to check size of available hard drive. I am using this code.

ssf = New SftpClient("ip", "port", "user", "password")
ssf.Connect()

Dim fpath As String = "/"

Dim res = ssf.GetStatus(fpath)

I am getting total, free and available nodes and blocks. But unable how to find available hard drive by this method. Or is there any other way to do it?

Solution

  • Use the SftpFileSytemInformation.BlockSize field to convert blocks to bytes.

    E.g.

    freeBytes = res.FreeBlocks * res.BlockSize
