# Filesystems

A *filesystem* is a high-capacity regional file store you can attach to your instance to store datasets and back up system state. In most regions, each filesystem has a capacity of 8 EB (8,000,000 TB), and you can create up to 24 total filesystems. In the Texas, USA (us-south-1) region, filesystems are currently limited to 10 TB of capacity.

For information on how filesystems are billed, see the [Billing overview](../billing/#filesystems).

## Accessing your filesystem

### Accessing from another instance or a 1-Click Cluster

To access a filesystem from within Lambda Cloud:

- The filesystem must reside in the same region as the instance or cluster.
- You must attach the filesystem to your instance or cluster at the time that the instance or cluster is launched.

Note

Filesystems cannot currently be transferred between regions.
