What Are ".OLD" Directories?

If you previously updated to FH 5 version 5.1.24 or less (that is, you go from one version of FH 5 to a version up to version 5.1.24), the update created a copy of all original FH 5 folders that are modified as part of the update process. The naming convention works as follows:

<directory name>.OLD

where directory name is the name of the directory containing files that are changed (for example, DATA).

In the event of an interrupted or failed update, the original files are still available in the directory copy.

Versions greater than FH 5.1.24 do not create *.OLD directories.
