Where can I store files for downloading?

I have some Word and PDF documents of info that people will need to download and reivew before completing some forms. 

Is there any storage space on the JotForm site where i can upload and store files and create links on forms to download the documents? 

I also need to be able to upload replacement documents without having to always re-create the links.  The names of the replacement files would be the same so they woudl truly repalce the files.

Unfortunately, there is no additional space provided apart from the storage space provided as per the subscription. This storage space can be used only for the files received through the submissions. It is required to store the files in your external server or may use any cloud storage space like Google Drive or DropBox so that you may link them on the form using a text field.

Hope this information helps!
