Dear Support I have read through: Version 2093: New Chartbook Format, Better Data Management in Sub Instances, Other and I am currently using version 2118. Following the version upgrade from 2073 where I had 11 chartbooks - I now have 13. The 2 additional chartbooks have the mentioned *.backup2092.cht. Please would you answer the following: 1. Why have only 2 of the 11 chartbooks been backed up? 2. The thread mentions a reduction of about 20-27% however of the two chartbooks that that were saved as *.backup2092.cht. A.cht = 9KB (95% reduction) and A.backup2092.cht = 193KB? B.cht = 90KB (97% reduction) and B.backup2092.cht = 2875KB? I am obviously concerned as to what might be missing now these have been reduced by such a degree. Ideally I don't want chartbooks and backups in my Data folder but I am concerned about deleting the backup as there is a significant difference in the file size. As always I look forward to your assistance and as much information as your time allows. Kind regards |

This is from the notes for version 2111: Added support for file compression for Chartbooks. This reduces the file size by 98%. In version 2118 and higher, when a Chartbook is saved which uses compression, a backup of the existing Chartbook is made with the suffix .backup2109 followed by the standard file extension.
