I have a file named test.png. Windows 10 shows a thumbnail preview in file explorer just fine.
I'd like to rename it to test.abc and have the thumbnail preview still work.
Following forcing thumbnail preview for custom file format (which was for Win 7) hasn't worked. I get a default thumbnail.
Copying the registry entry for .png and editing in the different extension hasn't worked. Again, default thumbnail.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.abc]
@="pngfile"
"Content Type"="image/png"
"PerceivedType"="image"
[HKEY_CLASSES_ROOT\.abc\OpenWithProgids]
"AppX43hnxtbyyps62jhe9sqpdzxn1790zetc"=hex(0):
"AppXcdh38jxzbcberv50vxg2tg4k84kfnewn"=hex(0):
"LibreOffice.Png"=" "
"pngfile"=""
[HKEY_CLASSES_ROOT\.abc\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"
Is something different in windows 10? Some additional step I'm missing? Something I don't understand?
