# Managing a workbook ### Maximum workbook size Workbooks have a maximum size limit: the total size of all the files in a workbook cannot exceed 5GB for users on the DataLab Starter plan or 20GB for users on the DataLab Premium plan. This is a per-workbook limit, so free users could have 3 workbooks with 4 GB each, for example. If the total size of all the files in a single workbooks exceeds the limit, you can no longer edit that workbook: through the file browser, you can remove files from the workbook filesystem to go below the limit again. ### Saving your edits All your edits are automatically saved. If you close and re-enter the workbook at a later point in time, all your work from before is saved. You can review and restore past versions of your notebooks through [Version history](/work/version-history.md). ### Renaming a workbook 1. Click on 'File > Rename workbook' in the toolbar. 2. In the modal that appears specify the new workbook name and click "Rename Workbook". ### Changing the workbook language You can use either **Python (version 3.8 or 3.10)** or **R (version 4.2 or 4.4)** to execute code in your notebooks. The default language of your workbook is guessed based on your previous workbook. If it can't be guessed, you will be asked to specify a language. To change the programming language yourself, click "Environment > Session Details" and select the programming language in the dropdown. Note that this will not automatically edit/translate any code that may already exist in notebooks (e.g. you still have to convert a `pd.read_csv()` into `readr::read_csv()` when switching the language from Python to R).

Open up the Session Details

Session details dialog, where you can update the language

#### Python 3.8 versus Python 3.10 Python 3.10 comes with a lot of updated pre-installed packages compared to Python 3.8, most notably Pandas 2.x instead of 1.x. For a list of breaking changes, see the [Pandas docs](https://pandas.pydata.org/docs/dev/whatsnew/v2.0.0.html#backwards-incompatible-api-changes). ### Deleting your workbook If you wish to permanently delete your workbook click "File > Delete Workbook". Confirm the action. **Deleting a workbook is irreversible!** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
