This is the default program installation directory. There is no reason for you to access any of the files in these folders. The report files you save are not kept here; usually they are kept in the report folder.

Depending on what PRL Reporting Software Option (and version) you are using the installation folder may contain the  Option A, Option B, or Option C programs, blank “templates” for  Option B Excel workbooks, and supporting libraries; older versions of the PRL Reporting software installed each option into its own sub-folder.
