Is there a problem using the getSize method for getting the content length? @Override public long contentLength() throws IOException { return this.fileObject.getContent().getSize(); }

@ptahchiev thanks for the PR but there hasn't been a lot of traction of the community and the related issue was closed as a result. I am going to close this as well.
