    Upload Virus or other bad files to Dropbox Folder?

    Asked by Annette on August 08, 2012 at 09:13 PM

    I'm thinking of adding an upload form to my website that would allow clients to upload their files to me using my drop box folder but I'm wondering about the security of it?  Can't anyone upload any file that way?  Is there a way to maybe put a password on the folder or something like that?  


    Thanks so much!

    Hello Annette

    First of all let me tell you that our servers are compliance with security. You can also embed the form using a secured embed code, to do this

     Go to Setup & Embed > Embed Form
    Choose Source then select the "Secure Form" check box


    Then choose the type of code you need ( Embed or Iframe are the most common used)


    Moreover , you can set specific file extensions to your upload button

    Simply click on the settings button and select Show Properties


    Then set the type(s) of  extension(s) file you will allow to and separate them by a comma  (rtf,pdf,jpeg,png,mp3)


    Do not hesitate to ask for more help . We are always glad to assist

    Hi Jeanette, thanks for your response.  I should know this, but, what would a "secure form" do? How would that protect my computer?

    Thank you,

    When a form is securily embedded it protects data by encrypting files while traveling through servers.

    But, I think your concern is regarding to the risk of getting infected of any malware, right?

    This is something SSL does not do,  like I said, secure forms (SSL) only encrypts data  . No matter which kind of data they are sending to you.  But once you download the data into your computer , you would need a real protection antimalware software which will detect the type of algorithm coming into data and will filter malware from clean files
