DataFlex index file description
The k9 file extension is associated with DataFlex and used for index files.
In DataFlex 2.x, the K9 index was always a 'batch' index, which means its contents were not updated when the datafile was updated. Batch indexes are only updated when the index is (re)created with dfindex or dfsort, depending on which version of DataFlex you have. This provided some advantages in certain situations, but most of those advantages have become obsolete with the faster computers and larger hard drives we enjoy today.
Depending on your backup medium, it can be faster to simply reindex a datafile versus restoring the file from the backup medium.
