Windows – Copy files from Mac OS 9 to Windows 7

GnuPG encryption!

$ gpg -e mysecretfile
You did not specify a user ID. (you may use "-r")

Current recipients:

Enter the user ID.  End with an empty line: 

$ ls *.gpg
mysecretfile.gpg

The file mysecretfile.gpg is now encrypted, in a way such that only the person (Bob McBlah) can decrypt the file (asymmetric or public-key crypto).

The file can safely be sent using any medium capable of sending a file (netcat, email, FTP, dropbox, mediafire.com etc etc), with practically no risk of interception.

If you use the -a "ASCII armour" flag, the encrypted file (which would be named mysecretfile.asc) is plain ASCII text, which can be sent in any medium that can send ASCII text, so answers to any other "how can I send an x MB file" question would applicable..

For a solution to your specific problem, perhaps a simple Python script could be written using the BaseHTTPServer module:

import sys
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer

thefile = None

class MyHandler(BaseHTTPRequestHandler):

    def do_GET(self):
        global thefile
        try:
            if self.path == "/":
                f = open(thefile)

                self.send_response(200)
                self.send_header('Content-type', 'application/x-gpg')
                self.send_header('Content-disposition', 'filename="%s"' % thefile.replace("\"", ""))
                self.end_headers()

                self.wfile.write(f.read())
                f.close()
            else:
                self.send_error(404, 'File not found: %s' % self.path)

        except IOError:
            self.send_error(404,'File Not Found: %s' % self.path)

def main():
    global thefile
    if len(sys.argv) == 2:
        thefile =  sys.argv[1]
    else:
        print "Usage: %s [path to served file]" % sys.argv[0]
        sys.exit(1)
    try:
        server = HTTPServer(('', 8080), MyHandler())
        print 'Started server on port 8080'
        server.serve_forever()
    except KeyboardInterrupt:
        print 'Keyboard abort, shutting down server'
        server.socket.close()

if __name__ == '__main__':
    main()

Save it as servefile.py and run as python servefile.py /path/to/my/file.gpg

The above code is not exactly great, but should be fine for one-off transfers.

you can use "allwaysync" (free utility for windows) to sync folders http://allwaysync.com/download.html it can sync both locations, or you can select one as a source and one as a destination can propagate and move modified / deleted files to user specified folders

very good and light weight - can be scheduled via task scheduler or windows batch.
