The hki2 file extension is associated with WinHKI Archiver, a Microsoft Windows program for creating and extracting compressed archives. HKI2 is the program's default archive format.
Because WinHKI is a specialized and less widely supported archiver, HKI2 files are uncommon and may not be recognized by current general-purpose archive utilities.
As far as we know, an .hki2 file can only be extracted using WinHKI Archiver on Microsoft Windows. Use the program's extraction function to access the files contained in the archive.
Other archive programs may not support the HKI2 format.
No reliable direct converter for the HKI2 format is known. Extract the archive with WinHKI Archiver, then create a new archive in a format supported by the required archive program. Repacking may otherwise be problematic or impossible.
