Do, for example, the following:
1. Create a new schema in the Workflow Designer: "Read alignment" > "Write alignment".
2. Input two or more files in the "Input files" parameter of the "Read alignment" element (for example, "input1.aln", "input2.aln" and "input3.aln").
3. Input a name of an output data file in the "Output file" parameter of the "Write alignment" element (for example, "test.aln").
4. Run the schema.
=> The schema ran successfully.
5. Search for the files on the file system.
!=> There are three output files: "test.aln" (equals to "input3.aln"), "test_oldcopy1.aln" (equals to "input1.aln") and "test_oldcopy2.aln" (equals to "input2.aln").
These names are not clear enough and could be improved.
