I believe that file type is property of local files only. The remote file system can use very different filename conventions, not compatible with local ones. In such case the file type column would contain senseless information.
I will agree with you. However, let me point out that we are using WinSCP, which means that the end user is running Windows. Since Windows has fairly reliable file extensions, it's sensible to think that the user is uploading to a server where those file extensions are also going to be still in place (images, .php, .html, etc., etc.).
There have been a couple of times that I've wanted to bring back all of a certain file type in a directory that contained many files of different extensions. Since the directory was so large, and there's only *exclude* file mask instead of an *include* file mask, this was a chore. However, this was before I found out that you could sort by file extension via the menu bar, so now it's not an issue =)
Thanks, for your continued dedication, though. There's a lot of people out here that really appreciate your work and support. =)
