To manipulate it with Desktop applications, perhaps sync it again…
May be you could look to Solid-shell
or use recursive-copy to a docker Solid Pod with persistant data folder, then you can edit the files in the data folder (beware it’s a hack, don’t delete/add files).
Recursive copy is not yet ready for prime time. A similar copyFolder() method is available in solid-shell (sol). Currently, they both work only in Solid space - in other words from one Pod to another. If you want to copy from a non-Pod to a Pod, use upload() and download() in solid-shell.
