File Manager

The File Manager lets you upload files, organize them in folders, share via public links, and let AI agents read and create files. Access it from Files in the sidebar.

Uploading Files

1. Go to Files.
2. Click Upload or drag and drop files onto the page.
3. Select up to 10 files per upload.

Files can also be attached in the Chat — drag files onto the chat input or click the attachment button.

Supported Formats

Category	Extensions
Images	.jpg, .jpeg, .png, .gif, .webp, .svg
Documents	.pdf, .docx, .xlsx, .pptx, .txt, .rtf, .csv
Code	.py, .js, .ts, .jsx, .tsx, .java, .go, .rs, .rb, .php, .html, .css, .scss, .json, .yaml, .yml, .xml, .md
Archives	.zip, .tar, .gz
Audio	.mp3, .wav, .ogg, .m4a

Executable files (.exe, .bat, .sh, .dll, etc.) are blocked for security.

Validation

Every upload goes through three checks:

1. Extension whitelist — only allowed file types are accepted
2. MIME type verification — file content is inspected to prevent disguised executables
3. Quota check — file size, total storage, and file count are verified against your plan limits

Storage Limits

	Free	Pro	Harness	Team
Max file size	10 MB	10 MB	10 MB	10 MB
Total storage	100 MB	100 MB	100 MB	100 MB
Max files	50	50	50	50

TIP

Storage limits are configured per pricing tier by the admin. The values above are defaults — your plan may have different limits.

Browsing Files

The Files page supports two views:

• Grid view — thumbnails for images, icons for other file types
• List view — compact table with name, type, size, and date

Use the search bar to find files by name, or the type filter to show only images, documents, code, archives, or audio.

Folders

Organize files into a folder tree:

• Create — click New Folder and enter a name
• Nested folders — use path syntax reports/2026/q2 to create multiple levels at once
• Navigate — click a folder to enter it, use breadcrumbs to go back
• Move files — drag files onto a folder card or onto a breadcrumb item to move them up the tree
• Rename — right-click a folder and select Rename
• Delete — deleting a folder moves its files to the parent folder (files are not deleted)

Drag-and-drop supports moving multiple selected files at once. Search scans all folders, not just the current one.

File Preview

Click a file to open the preview panel:

• Images — displayed inline with thumbnail
• Audio — playback controls
• Text and code files — content preview (first 200 lines)
• PDF and Excel — metadata displayed (use download for full content)

Downloading Files

• Click the download button on any file in the file list or preview panel.
• In chat, AI-generated files appear as clickable download chips.

Sharing Files

Workspace Sharing

Upload files with a workspace selected — all workspace members can view and download them. Only the file owner can delete or update.

Public Share Links

Share individual files with anyone via a public link:

1. Click the share icon on a file.
2. Toggle sharing on — a unique link is generated.
3. Copy the link. Anyone with it can download the file without logging in.

Public files are served at /api/files/public/:shareToken (no authentication required). Toggle sharing off at any time to revoke access.

Renaming Files

Right-click a file and select Rename to change its display name.

Deleting Files

Select one or more files and click Delete. Files are soft-deleted — they disappear from the list but are not immediately removed from disk.

Chat Integration

Attach files to chat messages:

1. In the Chat, click the attachment button or drag files onto the input.
2. Files are uploaded before the message is sent.
3. The AI can see attached files and use file tools to read their content.

AI-generated files appear as clickable download chips in the chat.

AI File Tools

AI agents have 5 built-in tools for working with your files:

Tool	What it does
file_list	Lists your files with optional type/name filtering
file_read	Reads file content — text files directly, Excel as CSV tables, PDF as extracted text
file_read_url	Provides a download link you can click in the chat
file_write	Creates a new file — text, Excel (.xlsx from JSON), or PDF (from text)
file_update	Overwrites an existing text file with automatic backup of the previous version

How to use file tools in chat

Ask the AI naturally:

• "What files do I have?" → agent calls file_list
• "Read my config.json" → agent calls file_list then file_read
• "Analyze the data in report.xlsx" → agent reads Excel as CSV tables
• "Create a Python script that processes CSV" → agent calls file_write
• "Fix the bug in my script" → agent reads, fixes, and calls file_update

Format support

Format	Read	Write
Text (.txt, .md, .json, .csv, .py, .js, etc.)	Content directly	Raw text
Excel (.xlsx)	All sheets as CSV tables	JSON array → spreadsheet
PDF	Extracted text from all pages	Plain text → PDF document
SVG	XML source	Raw XML
Images, archives, audio	Metadata only	Not supported

WARNING

File tools only access files owned by you (or shared in your workspace). The AI cannot access other users' files.
