--- title: Uploads description: Put files from your computer into Vythos — a folder you keep in step, or a single document you want to make a rule. --- Sources # Uploads Some documents aren't in a connected tool: a signed PDF, an exported deck, a contract someone emailed you. Upload them. ## Sync a folder from your computer **Sources → Local Files → Select folder.** Choose a folder; Vythos scans it, reads every supported file, and reports anything it skipped and why. Come back later and select the same folder, and only what changed is uploaded again — Vythos remembers which files it has seen and how big they were. ::: warning Chrome or Edge only Selecting a folder uses a browser feature that only Chromium browsers support. In Safari or Firefox the page says so. Everything else in Vythos works in any modern browser. ::: ## Upload a single document During setup, the *first rule* step takes one file and walks you straight into adding it as a rule. Afterwards, upload from Local Files and then add the document on the Playbook page. ## Making an uploaded document a rule **Playbook → Add rule → Choose from your sources → Your uploads.** Search by name; everything you've uploaded is there. ## Keeping an uploaded rule current Upload the file again, under the same name. The new text becomes the rule's next version, immediately — there's no waiting, because you've just handed Vythos the new document. Two things to know: - **The name is the identity.** `rate-card.pdf` uploaded again updates the rule; `rate-card-v2.pdf` is a different document. To swap to a differently-named file, add it and tick *replaces*. - **Uploads are personal.** If a colleague uploads a file with the same name, it's their document in their memory. It cannot overwrite your rule. A document that lives in Drive or Notion is better added from there — then it updates when you edit it, with nothing to remember. ## What can be uploaded Every format in the [file formats list](/reference/file-formats): PDF, Word, Excel, PowerPoint, Markdown, plain text, CSV, TSV, HTML, JSON and RTF. A file Vythos can't read is named with the reason rather than silently dropped — legacy `.doc`, `.xls` and `.ppt`, Pages, Numbers and Keynote files, images, video, audio and archives. Single documents during setup are limited to 20 MB. A scanned PDF — pictures of pages with no text layer — has nothing to read; re-export it from the original. ## Where uploads go Into your own memory, and nowhere else. Your colleagues can't search your uploads, and neither can the workspace owner. Making one a rule is what makes its *content* available to the people whose access covers that category.
