Supported Viewers / Clients

FileOpen Systems provides a versatile set of plug-ins/clients to access documents encrypted with the FileOpen software. These include a plug-in for Adobe Acrobat and Reader, a client for Microsoft Office documents, an iPad / iPhone app. We also offer a zero-client install solution, FileOpen Viewer.


The following free clients may be downloaded to view FileOpen-secured documents (along with the permission of the publisher), and may also be used in testing FileOpen document security solutions


Note that installation of the FileOpen Client software is not sufficient to enable opening of documents; the publisher's permission is also required.
