The Files Library at /files is a central repository for every file you have ever uploaded to ZeroTwo. Instead of re-uploading the same document every time you need it, find it in your library and attach it to any new chat in seconds.
The Files Library is per-account and private. Only you can see and access your files. No other ZeroTwo user has access to your library.

​
Accessing the Files Library

Navigate to the Files Library in two ways:
  • Click Files in the topbar navigation
  • Go directly to /files in your browser

​
What You Will See

The Files Library displays all your uploaded files sorted by upload date (most recent first, by default). Each file entry shows:
  • File name and extension
  • File type icon (document, image, audio, video, code, or data)
  • Upload date
  • File size
  • Which chat it was used in (hover to see the associated conversation)

​
Searching and Filtering

​
Re-Attaching Files from the Library

You can attach any library file to a new or existing chat without re-uploading it:
1

Open a chat

Start a new chat or open an existing one.
2

Click the paperclip icon

Click the paperclip in the prompt bar to open the attach menu.
3

Select 'From Library'

In the attach menu, choose the From Library tab (as opposed to uploading from your device).
4

Find and select your file

Browse or search your library. Click a file to select it. You can select multiple files (up to 10 on Pro+).
5

Confirm and send

The selected files appear as attachment previews. Add your message and send.
Re-attaching from the library is faster than re-uploading. Files are already processed and stored — they attach instantly with no upload wait.

​
Downloading Files

To download a file from your library back to your device:
  1. Hover over the file entry in the library.
  2. Click the download icon that appears.
  3. The file downloads to your browser’s default downloads folder.
The downloaded file is identical to your original upload — ZeroTwo does not modify or re-encode uploaded files.

​
Deleting Files

File deletion is permanent and cannot be undone. Once deleted, the file is removed from ZeroTwo’s storage and cannot be recovered. Download any files you want to keep before deleting them.
Delete a single file:
  1. Hover over the file in the Files Library.
  2. Click the delete icon (trash can) that appears.
  3. Confirm the deletion in the dialog.
Delete all files at once: Go to Settings → Data Controls → Clear Files → Confirm. This permanently removes all files from your account. Effect on existing chats: Deleting a file removes it from your library and from future access. However, the AI analysis already performed in past chat messages remains intact — the chat history retains ZeroTwo’s responses. Only the raw file attachment is gone.

​
Project Files

Files uploaded within a project are scoped to that project. They appear in:
  • The project’s own Files tab (accessible from within the project view)
  • The main Files Library, tagged with the project name
To view only files from a specific project:
  1. Open the project from the sidebar.
  2. Navigate to the project’s Files tab.
Project files follow the same search, filter, sort, and delete functionality as the main library.
Deleting a project does not automatically delete its files. Project files remain in your main Files Library tagged with the project name. Delete them individually from /files if needed.
