I've created an S3 file gateway and a file share. I've mounted the file share successfully on my EC2 Windows machine on the Z: drive. I can see all of the contents of the S3 bucket on the share.
If I upload a new file to the S3 bucket, I can see that the file share is synched to include the new file.
If however I copy a new file from my local disk (e.g. C:\) to the network share (Z:), the file never comes up on the S3 bucket. Why could this be?
