Mount with directory always on cache

I am working on implementing Rclone with an SSD for caching and an HDD for storage. Below is the configuration I plan to use.

rclone mount storage: X: ^
    --config ./rclone.conf ^
    --vfs-cache-mode full ^
    --vfs-cache-max-size 750G ^
    --dir-cache-time 24h ^
    --vfs-cache-max-age 24h ^
    --vfs-cache-poll-interval 24h ^
    --cache-dir C:\Cache ^
    --vfs-refresh ^
    --vfs-fast-fingerprint

Some directories are accessed more frequently than others and I would like to keep permanently cached on the SSD. Is there a way to achieve this with Rclone.

welcome to the forum,

afiak, that is not possible.
all cached items are treated the same when using vfs flags such as --vfs-cache-max-age

You are right but I think that as long as there is space in cache and nothing has to be evicted then expiring cache only means that cached file will be checked against source. If nothing changed it will stay in cache. So practically frequently used items can stay in cache forever without downloading them repeatedly every time they expire.
