Most zip archive files can be mounted as read-only folders to allow access to contents, including the ability to execute contained applications. DVD and CD images can be mounted in place as a read-only folder to allow access to contents. CFS files can be mounted in place as read-only folders to allow access to contents, including the ability to execute contained applications.
Private Folders can be created and used to store sensitive data files and applications in an encrypted and compressed container file. Private folders are created using a password to generate the encryption key. Once the password is provided at mount time, the protected contents become accessible in place through the file system. A few software applications specialize in modifying ISO images, but the format complexity make this too expensive for many applications.
CFS limits the format variety to ISO with specific extensions, relaxations, and usage guidelines. It also defines the image file container format that is to be used to provide features such as compression, file splitting, and password protection. As compared to ISO files, CFS is intended to simplify the implementation and consistency of reading applications, and greatly simplify the implementation of modifying and writing applications. The ZIP format is a staple format used in many applications.
All modern operating systems have some form of integrated support for ZIP files. Most archive formats do not consistently provide the compression indexing necessary to allow efficient random access.
Applications can utilize a variety of content protection mechanisms, without losing the ability to internally access content files through the file system. Games can package thousands of resource files into a single archive, yet still access resources through the file system. Archive files can be searched and accessed using any tools that are designed to work with the file system. Contents can be viewed, edited, and executed, without copying to unprotected storage.
Video and audio can be dynamically converted to an alternate format and used by any media player or processing program. Meta data in media files can be used to create alternate virtual file system views, while allowing the files to be accessed through the alternate view by any media player or processing application. Pismo File Mount Pismo File Mount is an operating system extension that enables application controlled virtual and user mode file systems.
