Blacklisted Extensions - Adobe 12001196 - Acrobat - Mac Manual

Section 6 Attachments
Users can indirectly manage the registry list of which file types can be opened and saved. In other words,
the list in Attachment black list can be extended one at a time as each attached file is opened.
Administrators can modify the registry.
To add a file to a black or white list, attach the new file type to a document and then try to open it:
1. Acrobat: Choose Document > Attach a File and attach a file type not on the black or white list (e.g.
yfile.xyz)
2. Open the file by highlighting it in the Attachments pane and choosing Open.
3. When the Launch Attachment dialog appears, choose one of the following:
• Open this file: Opens the files without changing the registry list.
• Always allow opening files of this type: Adds the file type to the white list and
prevents future warnings.
• Never allow opening files of this type: Adds the file type to the black list and does
not open it.
4. Choose OK.
