Among others I got DisplayWriter 4.0, OS/4 Warp Slovenian, dBase IV, Clipper, PowerPoint 4.0, Netscape Navigator 3.0, etc.

I found also some files with .CHT and .IMG extension which I can't find any software to open them. I know I made them, but unfortunately I can't remember which software was used. There is my family tree and chart of my height growing (which I'd like to compare now with my kids).

Some files I uploaded here: https://github.com/twooclock/KdajBi/tree/main/cht_img Files timestamp is 1990 and 1991.

Please help me find appropriate software!

So far I tried (does not work):

-ABC Flowcharter 3.01

-IBM Storyboard Plus 1.01 (5.25)

-Harvard Graphics for Windows 4.0

-Harvard Graphics for Windows 2.0 (3.5)

-HarvardGraphicsViewer

-PowerPoint 98

Googled, checked file.org, WinWorld, ... loosing hope... really makes me think about digital preservation.

Thank you!
