# Documents tab

The **Documents** tab shows the files attached to this asset: manuals, drawings, certificates and anything else your organization stores against it. It works the same way as the main Documents section, scoped to this one asset.

> **Screenshot placeholder:** the Documents tab on an asset with three or four files listed, showing the search box, type chips and the row actions.

### Upload a document

1. Click **Upload Document**.
2. Drop one or more files, or click to browse. Signal accepts PDF, Word, Excel, CSV and common image formats.
3. Set a type, and optionally a customer and serial numbers, for each file.
4. Click **Upload {n} File(s)**.

### Find, open and edit documents

Use the search box to search by name, description or serial number, and the type chips to filter by document type. Click a column header to sort the table.

Each document row offers **Open in new tab**, **Download**, **Edit name and tags**, and **Delete** on desktop. On a phone, tapping a PDF card opens it in a preview; other file types download instead. Tapping any card also shows these same four actions.

Editing a document lets you change its name, customer, linked serial numbers and tags. Deleting a document is permanent, so download a copy first if you might need it again.

### Notes

For the full set of search filters, field rules and error messages, see the Documents section, which covers the same upload, browse, edit and delete behavior used here.
