The attachments library is where every file in your vault lives in one place. It opens as a full-pane view in the center of the window, the same space your notes use. You leave it by opening a note again; there is nothing to close.

Opening the library
Open it from the Open attachments… command in the palette, or from its button in the sidebar.
Browsing
The library shows your attachments as a grid or a list. To find one:
- Search by filename: the search box matches file names (it does not look inside the files).
- Filter by type: All types, Images, or Other. The type filter predates audio attachments, so a voice note or imported audio file falls under Other.
- Sort: Newest first, Oldest first, or by name (A-Z / Z-A).
Seeing where a file is used
Each attachment shows used in N notes, computed live from your current notes, so there is no separate list to maintain or to fall out of date. Open that to jump straight to a note that uses the file. A file that no note embeds shows zero references; it is not deleted on its own and stays in the library until you remove it.
Cleaning unused attachments
Deleting a note never deletes the files it embedded, so files with zero references can build up. The Clean unused attachments command, run from the library, finds every file that no current note references. It reads your notes at the moment you run it to work out which files are still in use, then shows you the list to review before anything happens.
When you confirm, the files are erased from the vault. This is not reversible: there is no trash tier for a cleanup, so the review-and-confirm step is the only undo. Files that any note still embeds are never offered for cleanup.
Acting on a file
A per-item menu gives you preview, rename, export, and delete, the same actions covered in Attachments (rename changes the display name only; delete is explicit and leaves a tombstone in any note that embedded the file). Export opens a native Save dialog and writes a plaintext copy of the file to a path you choose; the copy you save sits outside the vault and is no longer encrypted.
Importing from the library
You can bring a file in from the library with its Import attachment picker. Importing makes the file available; embedding it into a note still happens in the editor, the same as adding any attachment.
