The file sizes are all 4096

let walker = sftp.Client{}.Walk(basedir);
walker.Stat().Size()  //will be 4096,   But they're actually different sizes

We need more example code. It should be expected:

// assume an existing valid `client *sftp.Client`
walker := client.Walk(basedir)

for walker.Step() {
  fi := walker.Stat()
  fmt.Println(fi.Name(), ":", fi.Size())
}

if walker.Err() != nil {
  fmt.Println("unexpected error:", err)
}

fi.Size()

Yes, on the MAC OS, all of fi.size () is 4096, but it's really any number

[puellanivis]

We still need more details. Example code and output produced vs output expected is necessary for us to figure out where things might be going wrong.

Hi,

I just did a quick test, using this code:

        walker := sftpClient.Walk("/Users/nicola/Downloads")
    for walker.Step() {
        err := walker.Err()
        if err != nil {
            fmt.Printf("walker error: %v\n", err)
            return
        }
        fmt.Printf("walker path %#v, isDir? %v, size %v\n", walker.Path(), walker.Stat().IsDir(), walker.Stat().Size())
    }

I get the expected output. The sftp client connects to OpenSSH running on MacOS and I launched the test program from both Linux and Mac and it works for me i both cases. Here is a sample output

walker path "/Users/nicola/Downloads/Azure Data Studio.app/Contents/Info.plist", isDir? false, size 3313

Please reopen providing more info if you still have this issue, thanks
