Since the MEPS format has been replaced by the MEPJS format, it is most often looked for a means to resave older projects to the new variant. Both .meps and .mepjs files are projects; the only significant difference is the version of Movavi Slideshow Maker from which they originate.
You can do this by simply opening the .meps file in Movavi Slideshow Maker version 23 or newer and saving the project again.
