Uploading Files: Limitations and Tips
When uploading files, it’s important to be aware of file size limits and unsupported formats to ensure smooth uploads, faster processing, and reliable performance.
Vault File Size Limits
Vault Limit | Maximum File Size |
|---|---|
Files per vault* | 100k |
GB per vault | 100GB |
Files per thread | 10k |
Files per review table | 10k |
MB per file | 100MB per file |
Excel files | 100MB per file, up to 1 million cells |
*While Assistant only allows uploading 50 files to a thread, vaults can store 100,000 files.
Tip: While Harvey supports file uploading to these limits, we recommend working with uploads below the maximum limit when possible for the fastest experience. If you experience an error while uploading, please review our Vault Error Troubleshooting Guide.
Supported File Formats
The following file types are supported in Vault:
- Standard document: .pdf, .docx, .rtf, .txt
- Email: .eml, .msg, .pst
- Spreadsheet: .xls, .xlsx, .csv
- PowerPoint: .ppt, .pptx
Create a New Vault
Each user can create unlimited vaults within their workspace. Once you’re ready to create a vault:
- Locate the Vault section in the left sidebar of Harvey and click the +

- Enter a vault name.
- Select files you wish to upload.
- Click Create in the bottom right corner to save.
Working With a Vault
First, from your Vault tab, select the vault you want to work with. Here, you can run a new query, view recent queries, manage files, and organize files into folders. Vault can also recognize documents with redlines/tracked changes.
- Start a query
- Ask a question in an Assistant thread: Get a single, aggregated answer across all documents using the current vault and additional knowledge sources (additional vaults, uploaded files, data sources, etc.)
- Create a review table: Run hundreds of queries at once over multiple documents in a table format.
- Use a Workflow: Instantly execute predefined queries tailored to specific use cases, such as M&A Deal Points or Litigation Court Opinion workflows.
- Create a draft document: Start a draft document from your vault.
Assistant Threads
You can perform Ask queries on vaults from either Vault or Assistant, with the same result: an Assistant thread generated from a vault.
- In Assistant, select files and sources, then add from vault. For detailed instructions on running a query with Vault files, please read Getting Started with Assistant.
- In Vault, enter your query in the text box.
Queries from either method will show up in the vault as well as in your History, indicating that Vault is the source.
Note: if you use more than one vault in your query from Assistant, that query is stored in your private history; you can always move it into a vault later.

Review Table
You can create and manage columns individually. Each column has a type, which is the kind of data expected in the cell. Review queries extract an answer that matches the column type.
- Column Types: date, duration, currency, number, verbatim, classify, and free response.
- Custom Sorting: columns can be sorted and formatted based on the data type.
- Export: you can export the whole table or sub-selected rows into an Excel sheet with an option to export verified cells as green and flagged cells as red.
- Document View: if you click a document, you can view each answer and relevant sources.

Vault Workflows
Vault streamlines transactional and litigation workflows, enabling you to complete key processes effortlessly—no typing required.

To start a workflow:
- Select the workflow that best matches your document type or click on View all for more options.
- Click Continue.
- If you select a review workflow,
- Confirm which columns you'd like to add to your review table,
- Select the files you want to review
- Click Choose.
- Once created, you can edit columns in the table.
- If you're not satisfied with the output after editing a column, we recommend creating a new custom prompt to format the data in a way that better meets your needs.
Recent Queries
Users can view their recent queries in each vault.
- Duplicate Table: To reuse a recent review table query, click the three dot menu on the far right and select Duplicate Table, then select the vault in which to reuse those columns.

Sharing Vaults
Users can share vaults with other users within your workspace. Sharing is restricted to members of the same organization, ensuring that only colleagues in your workspace can access shared items.
For more details on how to share projects, read Sharing Vaults.
Delete or Rename a Vault
From the Vault tab:
- Hover over the vault you wish to change.
- Click on the ellipsis menu in the top right corner of the vault.
- You will have the option to either Rename vault or Delete the vault.
- If you choose to delete your vault, you will be prompted again to confirm this decision as this action will permanently delete the vault and all associated sub-folders and files. Once a vault is deleted, it cannot be recovered.
Data Security & Privacy
Note: Documents uploaded in Vault are categorized as Customer Data in your platform agreement.
Storage Buckets
Vaults and data adhere to the specific workspace and territory-level data storage buckets assigned by Admins. For example, if data is saved in an EU storage bucket, Vault files will also be stored there.
Data Retention Period
There are two types of data retention periods related to Vault: Query Retention and Vaults & Data Retention.
- Query Retention: Queries are persisted as long as the vault, unless you have configured a custom query-level retention policy.
- Vaults & Data Retention: Vaults and data remain stored until the user deletes them, independent of workspace or territory-level retention policies, unless you have configured a custom vault-level retention policy.
All data will be deleted if your organization ceases to be a Harvey customer.
Note: Once vaults, queries, files, or data are deleted, they cannot be recovered by Harvey or the customer.
