It should be possible to freshen the files in an existing compressed file without selecting a file. I’m using version 9.51.01. Now I open an existing .zip, select “Freshen existing files” under the Options tab of the Add popup window and click Finish. An error window appears with the message “No File Selected.” This occurs even if the path is saved with the compressed file. It shouldn’t be necessary to select the file(s) which are already known to PowerArchiver and shown in the main window.
An even better option would be to add “Freshen” as an option in the pull-down Actions menu.
