Possible to search encrypted files?

Lets say you have thousands of encrypted files and you want to copy a file to your PC but don’t know the exact name of it. Is there a way to search using a word?

If it were me and you were on linux, i’d mount it and then search:

find /some/dir -iname “pattern

Alternatively, you could do a rclone ls and grep:

rclone ls acd:| grep -I pattern

Why not mount with decryption and just search normally ?

This is what I would do

rclone ls secret: | grep -i word
