When using the "Backup Show Archive" button in the Eos Shell, only showfiles with the extension .esf are saved
Description/Explanation of Issue
Eos v2.9.0 introduced a new file format, .esf2 which uses extra compression to make smaller showfiles. Unfortunately, the Shell > Maintenance > Backup Show Archive tool was not updated to include files with the .esf2 extension. This was corrected with Eos v3.0.0.
For consoles/computers that can install Eos v3.0.0+, install Eos v3.0.0+, then navigate to Shell > Maintenance and use the Backup Show Archive tool there.
For consoles/computers that cannot install Eos v3.0.0, files can be transferred using the File Manager in Shell > Maintenance > File Manager
