Hi, I LOVE WinSCP and have been using it for years.  I have a feature request:
A checkbox such as "Transfer hidden files"
Here is the problem.  On my local machine I have a SVN repository.  I manually SCP my changes up to the webserver.  The problem is that if I upload a directory, all of the hidden '.svn' directories that are present also get uploaded.  There is an '.svn' sub-dir in every directory, so these hidden transfers can be pretty significant.  Not only does this create a mess of hidden '.svn' folders all over the server, it also makes the upload take quite a bit longer, because the '.svn' dirs can get rather large.
I know there is an option to 'Show hidden files', which I have un-checked, however, if there are hidden folders within a folder I am uploading, they also get uploaded.  A 'Transfer hidden files' checkbox would solve this issue.
I hope you consider adding this trivial feature.  Thanks!
