Formats supported by the Composite Opener

The Composite Opener opens files that are not immediately accessible, for example, because they are compressed or nested in an archive. Files that are encrypted or corrupted are detected by the opener even if they cannot be opened.

The opener provides these functions depending on the file formats that it supports. The following lists show the formats that are supported with regard to:

  • File opening

Files of the same format can be encrypted or not. If they are encrypted, they cannot be opened.
