Hello Patrick,
Thank you for using Prime Mover plugin! Regarding your question – yes it’s possible to open and extract the WPRIME file. This is the complete tutorial.
However, please note that all information from the extraction is meant to be read only and should not be usable for complete manual restoration. It because the SQL file is not a raw SQL file but it’s designed for Prime Mover only processing. However – the plugins / themes/ media files inside the package can be manually extracted and copied if needed.
But for correct site package restoration – you should only use the Prime Mover plugin to restore the WPRIME package it to your site. If you cannot restore the package because it’s corrupt – you can refer to this guide on handling corrupted packages.
That’s it, I hope this answers this question. I’m marking this one as closed. Feel free to open a new ticket if you still need technical assistance. Thanks!
