The Security settings are used to determine the actions that PDF-XChange Editor takes when documents attempt to open files/attachments/sites:
•There are four options when the software is opening a file or an attachment:
•Use Trusted/Untrusted list, which can be specified using the Trusted/Untrusted locations and names text box. If the file/attachment is not specified then PDF-XChange Editor will prompt before opening.
•Prevent it, which prevents all files and attachments from being opened. The Attachments pane can be used to open attachments when this option is enabled.
•Allow it, which allows all files and attachments to be opened.
•Allow PDF(s) and use Trusted/Untrusted list for other, which allows all PDF files/attachments to be opened and refers to the Trusted/Untrusted list for other formats. If a file/attachment is not specified in the list then PDF-XChange Editor will prompt before opening it.
•There are three options when the software is opening a site:
•Use Trusted/Untrusted list, which can be specified using the Trusted/Untrusted locations and names text box. If the site is not specified in the list then PDF-XChange Editor will prompt before opening it.
