I read the documentation for the plugin. If during the import I choose the mode "A selection of folders and media", will the file be formed only with the structure of the selected directories or will it also contain the images themselves?
Of course, the folders structure and its media will be exported also.
Then you can import them on the other site.
If the exported folder contains a large number of images, then the export file may turn out to be large. Are there any restrictions on the size of the exported file? Or maybe restrictions will appear when importing such a file?
