The user uploads a file file1. Later the user uploads a set of files {file1,file2,file3}. If the file1 has not changed between the last and the current upload, the E2EE Client notifies an error "Container has not changed".
In a different case (the user first uploads file2 and later uploads the set {file1,file2,file3}, where the file2 has not changed, the E2EE Client uploads file1, recognizes file2 as the one that has not changed and fails to upload a new file file3).
