# The Vault
> Where your documents live: private, organization and project vaults, uploads, versions, folder sync and permanent deletion.
The **Vault** is Casa Conect's document store. Everything the agent reads and drafts lives here, along with everything you upload, file from email, or sync from a drive. Open it with **Vault** in the sidebar. It appears as a panel beside whatever you are working on.
## Three kinds of vault
| Vault | Tab | Who can see it | Needs Casa Conect OS |
| :--------------- | :------------------ | :----------------------------- | :------------------- |
| **Private** | *Private* | Only you | No |
| **Organization** | *Organization* | Members of your organization | Yes |
| **Project** | Inside each project | People who can see the project | Yes |
Folders nest as deeply as you like, and items keep the order you arrange them in. The list refreshes by itself when a colleague or the agent adds something.
Put working documents in the **project** vault. That is where the agent looks first when you work in a project or on one of its matters, and it is where [Populate](/workflows/populate) finds its sources.
## Add documents
Drag files onto the vault, or choose **New → Upload File**. Up to **25 files at a time**, **50 MB each**. Keep the browser open until the upload completes.
**New → New document** starts a blank document in the [editor](/documents/editor). **Create Folder** adds a folder.
File attachments from an Inbox conversation, or have the agent do it.
Link a Google Drive, OneDrive or SharePoint folder and keep it in sync.
### Accepted file types
| Kind | Extensions |
| :------------ | :---------------------------------------------------- |
| Documents | `.pdf` `.docx` `.doc` `.odt` `.rtf` `.txt` `.md` |
| Spreadsheets | `.xlsx` `.xls` `.ods` `.csv` |
| Presentations | `.pptx` `.ppt` `.odp` |
| Images | `.jpg` `.jpeg` `.png` `.webp` `.heic` `.heif` `.avif` |
| Archives | `.zip` |
What you can *do* with a file depends on its type:
| File type | View | Edit in Casa Conect | Agent can read |
| :------------------- | :-------------------------------------- | :---------------------------------------------------- | :-------------------------- |
| Word (`.docx`) | Yes, paginated like Word | Yes. See [Word documents](/documents/word-documents). | Yes |
| Markdown, plain text | Yes | Yes | Yes |
| PDF | Yes, including password-protected files | No. PDF is an export format. | Yes |
| Images | Yes | No | Where text can be extracted |
| Other accepted types | Download | No | Where text can be extracted |
Every upload is **scanned for malware** before it can be opened, and **indexed for search** shortly afterwards. See [Search](/documents/search).
## Work with an item
Open an item's menu for **Download**, **Download as Word (.docx)**, **Open in Word**, **Version history**, **Rename**, **Move**, **Add to matter** and **Delete**.
**Open in Word** downloads a copy that stays linked to the vault. When you save it from the [Word add-in](/word-add-in/overview), it comes back as a new version of the same document, not as a duplicate.
## Versions
Every document has **one history**, whatever changed it. Open **Version history** to see each version with its origin:
| Origin | Created when |
| :----------------------- | :----------------------------------------- |
| **Uploaded** | You uploaded the file, or a new copy of it |
| **Edited in the editor** | You saved a version from the editor |
| **Saved from Word** | You saved from the Word add-in |
| **Agent edit** | The agent edited the file |
| **Changes resolved** | Tracked changes were accepted or rejected |
| **Synced from provider** | A linked drive delivered a newer copy |
| **Restored** | An earlier version was restored |
**Restore** makes an earlier version current again. Nothing is lost: *the current content is kept in the version history.*
## Delete
Deleting is **permanent**. There is no trash. Deleting a folder deletes everything inside it. The files, their versions and their search index are removed, and anyone who has the document open is disconnected.
The agent is instructed to confirm with you before it deletes anything it did not create in the same conversation, and deletion is a **sensitive** action under [permission levels](/agent/permission-levels).
## The viewer
Opening a file shows it in the **document viewer**, which can be docked to the side or expanded, with a page list and zoom. Up to 20 files can be open as tabs.
For Word files the viewer is candid about how faithful the page layout is:
| Banner | Meaning |
| :------------------------------------------------------------------------------ | :-------------------------------------------------------------------------- |
| *Page breaks match Word's print layout.* | The pages you see are the pages Word would print |
| *Page breaks are approximate…* | Word may lay the document out on a different number of pages |
| *Page layout is approximate — this document uses fonts we can't match exactly…* | The document uses a font Casa Conect cannot reproduce. The banner names it. |
For an exact layout with unusual fonts, turn on **Embed fonts in this file** in Word (*File → Options → Save*) and upload the document again.
Word files with tracked changes show a **Tracked changes** panel in the viewer. See [Tracked changes](/documents/tracked-changes#in-the-viewer).
