Creating Digital Products
You do this by following the steps above but you add an additional custom field which will indicate the location of the digital file representing the digital product.
First, you need to upload the file to: /wp-content/uploads/dpsc_download_files
Next, add a custom field with the key digital_file and the value should be the actual File Name of the file representing the digital product. Note that this is case sensitive.
If you are using the graphical user interface, please put the file name in the ‘Digital File’ field.
Digital file security
The digital files are stored in “/wp-content/uploads/dpsc_download_files/”
The link that is sent to customers is generated by creating a temporary duplicate file in “/wp-content/uploads/dpsc_temp_download_files/”.
So all you have to do is disable directory listing for these directories and you can password protect the “/wp-content/uploads/dpsc_download_files/” for extra precaution.
