GNOME Bugzilla – Bug 766644
Process ISO files regardless of the filename extension
Last modified: 2020-11-11 19:12:27 UTC
When an ISO9660 file is renamed and longer has the .iso extension, then it can no longer be opened by file-roller. Please make file-roller handle ISO files regardless of the filename extension. One use case is to extract AppImages which are ISO files but with a custom header and no filename extension. file-roller could check for the presence of the "CD001" magic that identifies ISO9660 files.
At least for MIME types that inherit from the ISO9660 mime type, file-roller should be able to process files regardless of the filename extension. For example, the AppImage MIME type application/x-iso9660-appimage is a sub-class of application/x-iso9660-image and was added to shared-mime-info recently. https://cgit.freedesktop.org/xdg/shared-mime-info/commit/?id=01fa61fc002afdcf43f61e7df2d6cc6f6968d8d2 Hence, file-roller should be able to handle files with the application/x-iso9660-appimage mime type, but currently only does so if the filename ends in ".iso".
bugzilla.gnome.org is being replaced by gitlab.gnome.org. We are closing all old bug reports and feature requests in GNOME Bugzilla which have not seen updates for a long time. If you still use file-roller and if you still see this bug / want this feature in a currently supported version of GNOME (currently that would be 3.38), then please feel free to report it at https://gitlab.gnome.org/GNOME/file-roller/-/issues/ Thank you for creating this report and we are sorry it could not be implemented (volunteer workforce and time is limited).
