results = Import[#] & /@ FileNames
Thank you for the tip. It is exactly what I am looking for, but unfortunately, I get the following error:
"SetDirectory::cdir: Cannot set current directory to..."
which apparently means that Mathematica cannot find or set the directory. However, the file path that I use works fine in my FTP client and other languages that I use. My file path for the remote Mac looks like this.
I then executed
and got the error described above. I also tried this form of the path
and got the same error. I'm guessing that Mathematica is not able to send a password like an FTP client does, or perhaps Mathematica uses SFTP by default, whereas I have FTP running on the remote Mac. I cannot keep the submissions in a public folder because there is other confidential information about student accounts. I suppose I could use LiveCode or a CGI to download the submissions to my local hard drive and then use Mathematica to process them, but it would be nice to be able to use Mathematica for all of the steps.
By the way, your other suggestions about signed CDFs is interesting.
