# Uploads (/docs/library/uploads)

Choose **Upload** in the library, or drop files on it. Uploading takes an admin, developer or editor role in the Space.

## Where a file lands [#where-a-file-lands]

In the folder you have open, unless one of the Space's [upload rules](/docs/library/rules) matches its name: then it goes to the rule's folder (made when missing) and gets the rule's tags. When a rule matches any of the files you drop, the library shows where each will go first, and uploads once you confirm.

## In parts [#in-parts]

The library sends every file in parts of 10 MB, straight to storage, three files at a time, so one large video doesn't hold up the rest. A part that fails is sent once more; if it fails again, that file's upload is cancelled and nothing is kept. A file only appears in the library once all its parts are in.

That makes large files work: video, print files, raw photos. A file goes up in at most 10,000 parts, so up to about 100 GB.

A file needs a name with an extension (`photo.jpg`). The name is made safe for URLs: spaces and special characters become `-`.

## Size limits [#size-limits]

| How a file comes in                                        | At most                      |
| ---------------------------------------------------------- | ---------------------------- |
| Uploading in the library                                   | About 100 GB (10,000 parts)  |
| [Replacing a file](/docs/library/details#replacing-a-file) | 50 MB, or 100 MB for a video |
| A row of a [CSV import](/docs/library/imports)             | 50 MB                        |
| An agent's `uploadFile`, from a URL                        | 50 MB                        |

Imports and `uploadFile` fetch the file from an `https` URL on a public host, and refuse it when its bytes aren't the type the URL claims. A larger file is uploaded in the library.

## After the upload [#after-the-upload]

- An image gets its width and height measured.
- With a Shopify store connected and its catalog indexed, a new image is looked at for the store's products: see [suggestions](/docs/shopify#suggestions).
