Steps to follow

To get links to files:

Create a bucket

In the Buckets section, click Create Bucket.
Enter the bucket name. The name must be unique and must not contain spaces or upper-case letters.

Learn more about the Bucket naming rules.
Select the region closest to your Tolokers. For example, for Tolokers from Germany: AWS Region → EU (Frankfurt) eu-central-1.
To make files in the bucket available by link, disable the option Block all public access in the Block Public Access settings for this bucket section.

Note. Files will be accessible to anyone with a link. We recommend using hashed file names to keep your files secure. You can generate hashes using online tools (for example, Online MD5 Hash Generator). Learn more about hashing.
Confirm changes.
If you want to enable version control, select Bucket Versioning → Enable.

To make your files easier to navigate, add tags.
Click Create bucket.

Note. You can set the lifetime of files in the bucket so that they are automatically deleted after a specified number of days. Learn more.

Upload files to the bucket

In the Buckets section, select a bucket.
On theObjects tab, click Upload.
Upload files

Select the files on your computer and click Add files.

Upload a folder with files

Select the folder with the files on your computer and click Add folder.

Create a folder and upload files

To create a folder in the bucket, click Create folder and upload files.

Note. All symbols except for Latin letters will be replaced with codes, and spaces will be replaced with plus signs.
Click Upload.
After the files are uploaded, click Close.

Copy links.

Select the uploaded file and click Copy URL on the Object tab.
All file links are created by the same template.

Links look like this:
```
https://<bucket-name>.s3.<region-code>.amazonaws.com/<filename>
Copied to clipboard
```
The link in the folder looks like this:
```
https://<bucket-name>.s3.<region-code>.amazonaws.com/<path-to-file>/<filename>
Copied to clipboard
```
Note.
To quickly get links to other files, copy the link to one of them and replace <file-name> with the names of other files.
In the file with tasks, paste the links in the column that matches the input data field to which this data is passed.

For example, if you want to use images in the image field, specify the file links in the INPUT:image column:
```
INPUT:image
https://mybucket.s3.eu-north-1.amazonaws.com/newfolder/image1.png
https://mybucket.s3.eu-north-1.amazonaws.com/newfolder/image2.png
Copied to clipboard
```
