Dear FSL experts,

Sorry for asking such a naive question but I am having troubles when trying to upload a compressed file in FreeSurfer.

I followed the instrucctions found in: https://surfer.nmr.mgh.harvard.edu/fswiki/FtpFileExchange

and all works till the last moment when I can not upload anything...I am missing something, but I do not know what. Here is what I have done:
