File Sharing

Built-in File Sharing

ArcBox mounts your home directory into each machine automatically:

/Users/<username>  →  /mnt/mac/<username>

Files sync in both directions with near-native performance. Changes made on your Mac appear inside the machine immediately, and vice versa.

Custom Mounts

Add additional mount points when creating a machine:

arcbox machine create --name dev --mount /path/on/mac:/path/in/machine

Or configure mounts in the machine settings panel in Desktop.

SCP and rsync

For machines without shared mounts, use standard file transfer tools:

scp ./file.txt dev.arcbox:/home/user/
rsync -av ./project/ dev.arcbox:/home/user/project/

See SSH for connection details.

Performance

Shared mounts use VirtIO filesystem passthrough for minimal overhead. Sequential read/write performance is >90% of native.

For workloads that are sensitive to filesystem latency (e.g., git status on very large repositories), consider working directly inside the machine filesystem rather than through a shared mount.
