File extension K5 description:
DataFlex index files have a .K* extension. The * of K* is a one or two digit number. Values of K* will range from K1 through K15.In DataFlex 2.x, the K10 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.
