What is an HKI1 file?

An HKI1 file is a compressed archive created by WinHKI, an archiving utility for Windows. It likely contains one or more media files, which have been compressed to reduce their file size. HKI1 files are similar to but compressed differently than .HKI2 and .HKI3 files.

More Information

WinHKI is an obscure archive utility developed by Hanspeter Karl Imp. It allows users to compress and archive files in one of three different formats. These formats, referred to as HKI1, HKI2, and HKI3, are optimized for use with different types of files.

The HKI1 format is optimized for compressing audio files, images, and videos. Notably, both the free and paid versions of WinHKI can create HKI1 files. (Only the paid version of WinHKI can create HKI2 and HKI3 files.)

How to open an HKI1 file

You can open HKI1 files with WinHKI (Windows). However, WinHKI is discontinued and no longer officially available online. Thus, if you do not already have access to WinHKI, you probably will not be able to open your HKI1 file.
