# Knowledge Data Storage Limit

> What counts toward your plan's knowledge storage, what happens when you reach the limit, and how to free space

Every document indexed with the **High Quality** [index method](/en/cloud/use-dify/knowledge/create-knowledge/setting-indexing-methods) stores its chunks as vectors (the numeric form that powers retrieval), and those vectors count toward your workspace's knowledge storage.

Each plan includes a fixed amount:

| Plan         | Storage |
| :----------- | :------ |
| Sandbox      | 50 MB   |
| Professional | 5 GB    |
| Team         | 20 GB   |

The workspace owner and admins can check current usage in **Settings** > **Billing** > **Knowledge Data Storage**.

## What Consumes Storage

Usage depends on how many vectors your documents produce, not on their raw file size. The more chunks a document is split into, the more vectors it produces.

<Info>
  In [Parent-child mode](/en/cloud/use-dify/knowledge/create-knowledge/chunking-and-cleaning-text), every child chunk becomes a vector.
</Info>

The embedding model matters too: each model outputs vectors of a fixed length, listed in the provider's documentation as its number of dimensions. For example, OpenAI's `text-embedding-3-large` uses nearly twice the storage per chunk of `text-embedding-3-small`.

As a result, a document can use several times its own file size in storage once indexed.

Documents indexed with the **Economical** method use keyword indexing instead of vectors and don't consume storage.

Usage reflects the actual storage your vectors occupy, measured periodically, so a delay is expected before the number changes after an upload or deletion.

## When an Upload Would Exceed the Limit

Every upload is checked before indexing. When the estimated total storage after the upload would exceed your plan's capacity, the document is kept in the document list but not indexed.

To bring it under the limit, split the file into smaller uploads, or raise the chunk size in the document's [chunk settings](/en/cloud/use-dify/knowledge/create-knowledge/chunking-and-cleaning-text) so it produces fewer chunks, though larger chunks make each retrieved passage longer and less precise.

Alternatively, upgrade your plan for more capacity, then try again.

## When Storage Is Full

Once usage reaches your plan's limit, the workspace can no longer add knowledge content.

Uploading documents, adding or editing chunks, restoring archived documents, and re-indexing operations such as changing chunk settings are all blocked, including in knowledge bases that use **Economical** indexing.

To restore these actions, free space or upgrade your plan.

If a downgrade or an expired subscription leaves your data above the new plan's limit, nothing is deleted: your apps can still retrieve from these knowledge bases, but adding content stays blocked until usage fits the limit or you upgrade again.

## Free Up Storage

Delete the documents or knowledge bases you no longer need. Their vectors are removed, and the space returns to your quota.

The usage shown in **Settings** > **Billing** refreshes on a delay, so the number takes a while to drop after a deletion.
