Nothing indicates that tib to tibx conversion, i.e. conversion of older Acronis True Image disk files to newer format is possible, despite the fact that many users would like to do this, for the reasons of saving disk space. Of course TIB format is still supported in latest versions of True Image and you can recover these images, just there is no way how to convert tib to tibx on file per file basis.
