I wish to trigger an AWS lambda function I upload a file to a specific folder in S3. There are multiple folders in the s3 bucket now. Is this possible and how do i do so?
Can you trigger an AWS lambda function when a file is uploaded to a specific folder in S3?

Yes, you can Configure Amazon S3 event notifications, filtering on object key prefixes (and/or suffixes).
See Configuring notifications with object key name filtering. A prefix could be dogs/, for example. That way, all uploads to a key beginning with dogs/, e.g. dogs/alsatian.png would notify.
Note that you probably don't actually have any folders in your S3 bucket, just objects, unless you created them using the AWS Console. There really aren't any folders in S3.
