I want to send lots of files to the spaces, however, I want to specify only a few file extensions.
I tried to use the “–include-from” pointing to a file with the list of extensions that I want to send but it does not respect the list and tries to send everything.

I searched but did not find any documentation on these specific parameters. Would there be any other way to send just a few specific extensions?

In the future I want to use sync to send only files that have changed from the same set of extensions.
