+GitHub Actions secrets are limited to 48 KB in size. If you have a large Rclone config file, you can compress it first using zstd.

+Compress and encode the rclone.conf file using this command `zstd -c rclone.conf | base64 -w 0` and paste it to `RCLONE_CONFIG` secret.

 ### Service account file
 To prevent the Rclone config file from becoming too large since you have a lot of remotes that uses the same service account file, use the `AnimMouse/setup-rclone/service-account-file@v1` action to add the service account file inside the Rclone config directory.
