DESCRIPTION

This sample gets files specified by the user from the
selected folder and batch processes them and saves them
as AI files in the user desired destination with the same
file name after tracing the raster arts in the files.

Modifications:
Line:43 or 44 - select GIF folder to process
Line: 49 - output SVG folder - (manually create the new folder i.e SVG/001/ etc.)
Line: 86 - image trace preset (the custom preset for me was [19] but it would be different for other users - most likely [18] - check out https://forums.adobe.com/message/7058957#7058957)
