.K10 File Extension

The k10 file extension is associated with DataFlex and used for index files.

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.

How to open:

The k10 files are used for internal purposes of DataFlex.

How to convert:

As far as we know, this .k10 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
