AVS/AVSI difference?

[Zarxrax]

Is there any difference in how functions with .avs and .avsi extension are handled? I was looking in the avisynth manual and only saw mention of .avs functions, but functions with .avsi extension seem to behave the same. Is there any difference at all, and if not, why do some functions use the .avsi extension?

Files with the .avsi extension are parsed automatically along with the rest of the 'plugins' dir. This allows you to create a script invoking a function in this .avsi without specifying it manually in your script.

Sometimes you get problems with files with .avsi extension. For some reason, the latest MCBob script will crash VDubMod if the script has the .avsi extension. If I import it in the script (so that it has the extension .avs), there are no problems.

.avs is the registered extension for the Windows VFW interface.

.avsi is the extension for auto-imported scripts in the plugin directory and is NOT registered to the Windows VFW interface.
