It behave like if i use "Save as" and the file name is added "Converted" - help me
That's the way indesign works with older indd docs.
you can save as current old doc as a new doc and make it still opened by: Shift+Ctrl+S
ID treats converted files as if they were new files the first time they are opened, and adds the [converted] to prevent you from accidentally overwiting the old version and making it impossible to use again in the version in which it was created. It's a REALLY good idea to save all converted files with a new name to preserve the originals as backup, and an even better idea to export the originals as either .inx or .idml from the original verison of ID, then open that in CC instead of the .indd file.
