Hello Experts,

I wanted to know if .imscc format files (CANVAS) are supported. I checked the below links and it didn't specify about this format. Also I tried loading a sample file on .imscc format but it gave error stating "You must enter a file with valid type. (WLF-5145012)"

Has anyone come across this format, any workarounds or other options do we have on this. Any possibility to convert .imscc format to other format (not sure if this is possible)
