Upload File Directory

Hi, I’d like to select the directory that files upload to when people fill out the form in the “file upload” field of the formidable form.  And I’d like that directory to be in the root of my site. Is that possible?

Security – Null characters

Hi – I was advised by my server company that when allowing surfers/users to upload files it is good to “check for null characters and non-printable symbols and automatically fail.” How would I do that with your form? Thank you!
