# Editor and uploads

> The size limits of DooFiles: the largest file the editor opens, and the largest file you can upload, which can be larger than the upload limit of PHP.

## Overview

This card sets two size limits: how large a file can be to open it in the [editor](https://doothemes.com/docs/doofiles/files/editor), and how large a file can be to [upload](https://doothemes.com/docs/doofiles/files/uploads) it.

Go to **DooFiles › Settings** and open **Editor and uploads**. Change the numbers and click **Save changes**. Saving asks for your password.

## The settings

| Setting | What it does | Default | Range |
|---|---|---|---|
| **Largest file the editor opens** | Larger text files cannot be opened in the editor. You can still download them | 2 MB | 1 to 10 MB |
| **Largest upload** | Larger files cannot be uploaded with DooFiles | 2,048 MB (2 GB) | 1 MB to 102,400 MB (100 GB) |

## Largest file the editor opens

Very large files make the editor slow, because your browser has to load and highlight all their text. 2 MB covers almost every code and configuration file. Large text files are usually logs or exports, which are easier to work with after downloading them.

When a file is larger, DooFiles tells you: *This file is 3.4 MB. The editor opens files up to 2 MB; you can download it instead.*

## Largest upload

PHP on your server has its own limit for each request, set by `upload_max_filesize` and `post_max_size`. The card shows yours, for example *64 MB*.

DooFiles does not depend on that limit: files over 1 MB go up in parts that fit within it, and DooFiles puts them together at the end. So **Largest upload** can be much larger than the limit of PHP, up to 100 GB.

When a file is larger than **Largest upload**, it fails with *Larger than DooFiles allows (2 GB).*

### Free space on your server

Before a large upload starts, DooFiles checks that your server has enough free space for it. If not, the upload fails with *There is not enough free space on the server for this file.* Free some space, for example in the [Space](https://doothemes.com/docs/doofiles/views/space) view, and try again.

## Settings set by a developer

If a row shows *Set by the … filter in the site's code.*, a developer fixed that value in the code of your site, and it cannot be changed here. See [Filters and constants](https://doothemes.com/docs/doofiles/developers/filters-and-constants).

## Troubleshooting

| Problem | What to do |
|---|---|
| *This file is 3.4 MB. The editor opens files up to 2 MB; you can download it instead.* | Raise **Largest file the editor opens**, up to 10 MB, or download the file and edit it on your computer |
| *Larger than DooFiles allows (2 GB).* | Raise **Largest upload**, or upload the file by FTP |
| *There is not enough free space on the server for this file.* | Free space on your server, or ask your hosting provider for more |
| Large uploads fail with a 502 or a timeout | Your server or a proxy cuts long requests. See [Server configuration](https://doothemes.com/docs/doofiles/guides/server-configuration) |
