# S3 Browser

S3 Browser is a Windows app for browsing buckets and uploading and downloading files. This page connects it with your account's own access key. Using a sub-user's key? See [S3 Browser with a sub-user key](/connect/desktop-apps/s3-browser-sub-user). Prefer video? [Watch the setup video](https://youtu.be/snJqhHzkvGo).

## Before you start

* A bucket — see [Create a bucket](/buckets/create-a-bucket).
* An access key from the same region as the bucket — see [Access keys](/access/access-keys).
* S3 Browser installed — [download S3 Browser](https://s3browser.com/download.aspx).

## Troubleshooting

| Problem                      | Fix                                                                                                                                                                                                                  |
| ---------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| The bucket list is empty     | With a sub-user key this is normal — add the bucket by name, see [S3 Browser with a sub-user key](/connect/desktop-apps/s3-browser-sub-user). Otherwise check that the REST Endpoint matches the region of your key. |
| Access denied or invalid key | Copy the keys again from **Access Keys**, without extra spaces. An Indore key does not work on the Mumbai endpoint, and the other way round.                                                                         |
| `SignatureDoesNotMatch`      | The secret key is wrong, or your computer's clock is off. See [Signature errors](/help/troubleshooting/signature-errors).                                                                                            |

For other errors, see [Access denied](/help/troubleshooting/access-denied) and [Endpoint and region](/help/troubleshooting/endpoint-and-region).
