Files not being decrypted by "decrypt-all" command?

I’m currently decrypting my instance with occ encryption:decrypt-all -vvv command, on Nextcloud 19 (to upgrade later to Nextcloud 21).

Command is still running, but i went trough the folders already decrypted (by the output of -vvv i can see them) so i downloaded a few by FTP.

ALL OF THEM are still encrypted. Is this normal? Are the files only writed/decrypted/wathever after the process finishes?

Also, all those files/folders still have the corresponding 'files_encryption/keys/files' folder in place, shouldn’t these be deleted while the files are being decrypted? Or, are they also deleted after the process finishes?

Thanks in advance for the input by someone who has already decrypted his files.

Maybe you’re lucky and still have the whole data folder and the config file? Then you could try this standalone script that works outside of Nextcloud to decrypt the files: https://github.com/syseleven/nextcloud-tools/blob/master/rescue/decrypt-all-files.php
