If you use the Domino CLI to work with projects on your local machine, you might find that storing large data files slows your download and sync operations, and fills up a lot of your local disk storage. To prevent this, store data in a Domino Dataset, and reserve your project files for the scripts and documents that you want to work with locally.
| Note | In a Domino Nexus deployment, CLI access to Datasets is only available in the Localdata plane. | 
To simplify your local workflow:
- 
Create a Dataset in your project, and write your large data files to it. 
- 
After the files have been written to the Dataset, remove them from your project files. 
- 
Fetch a clean, lighter-weight copy of your project. 
- 
Update your code to reference your data files in their new location, at: /domino/datasets/local/<dataset-name>/
- 
When everything is working properly, delete copies of the project that have the large data files in them from your local machine.
