Help needed with identifying file/software format

Hi guys. A while ago I had the layouts to my short film scanned and compiled on some animation software. I forgot the name of that program. Could anyone please help me identify the software these files belong to? Below is a tree with file names of one of the scenes. Comments in parentheses are mine.

Sc-008 (main folder)
…A.lvl (main subfolder)
…kvd (file? blank icon)
…A_1.drw (subfolder of main subfolder)
…draw.fil (file, blank icon)
…draw (some script file judging by the icon)
…draw (file, blank icon)
…draw.lin (file, blank icon)
…draw.lut (file, blank icon)
…kvd (file? blank icon)

Any help will be appreciated:)
