You can't currently upload PSD files over 6MB. This is because its mimetype is `image/vnd.adobe.photoshop`. We think this is an image, and non-GIF images have a limit of 6MB. To fix this, we could do one of two things: 1. Add a special case for PSD files 2. Increase the size limit for unsupported image types such as this I went with the second option. Tested this by: - adding automated tests - uploading a ~9 MB PSD file - uploading a ~1 MB PNG - uploading a ~27 MB PNG (which worked because it's converted to a smaller JPEG) - uploading a ~50 MB text file - trying to upload a ~500 MB text file (which failed, as expected) Addresses [DESKTOP-1168][].
