# S3 File Storage With the S3 Datasource Plugin, you can connect to your Amazon S3 Storage to upload and manage Files. ### Prepare Amazon S3 Buckets

Next to Buckets, you need to create a User to configure Access Keys

Create a Amazon AWS User, give with a Policy the desired Access for your Buckets

Now you can create the Access Keys

The Access Keys are needed to connect to your S3 Buckets

### Create a Datasource to Connect to your Bucket To use Amazon S3, you need to connect to your Buckets.

You need to have at least one Bucket as also your Access Key for S3

The URL contains the Amazon AWS Region, in which you created the Buckets. This does not affect replica regions. ``` https://s3..amazonaws.com ``` ### Upload Files With the help of the file upload component, you can now gather the data that you want to upload as Fle to your Bucket. There are two possible file types in general. * Text based Files like JSON or CSV * Binary Files {% hint style="info" %} Binary files are represented in the Browser as base64 encoding. However, after the transport to the S3 Bucket, they will be available as binary files. {% endhint %} From the possible actions of the S3 Datasource Plugin you can choose "Upload file" and fill in the settings.

### List Buckets and Files Choose "List Buckets" to get a JSON List of your S3 Buckets.

You can get all your S3 Buckets as Data List.

```json // Response of "List buckets" [ { "name": "lowcoder-documentation-bucket" } ] ``` With the name of the Bucket you can now request a list of all Files.

Get a List of all Files in your Bucket as JSON

``` // Response of "List files" [ { "name": "open_issues.json", "size": 247285, "lastModified": "2023-06-24T18:28:51.000Z", "signedUrl": "", "url": "https://s3.eu-central-1.amazonaws.com/lowcoder-documentation-bucket/open_issues.json" }, { "name": "test.json", "size": 236646, "lastModified": "2023-06-24T18:17:13.000Z", "signedUrl": "", "url": "https://s3.eu-central-1.amazonaws.com/lowcoder-documentation-bucket/test.json" } ] ``` ### Read / use Files Based on Bucket & File name you can now request the Data of Files.

Get the file as JSON / Text or base64 encoded.

An alternative way to access the File is via the secure Link (Signed URL). To get the "signed Link URLs" for your files, just use the "List files" method including the "Return signed url" checkbox.

Get direct accessible Links of your files

You can now use the URL of each file and for example, display it in the File viewer or with the [Image Component](https://docs.openflower.org/build-applications/app-editor/visual-components/image). ### Delete Files You can use the Method "Delete file" to ... delete a single file from your Bucket.
