Hi Jeff, see http://www.blender.org/development/architecture/blender-file-format/
the first seven characters are always "BLENDER" for uncompressed blend files, but the file could be gzip-compressed, and then the first 7 characters will be different.

(for a total of 10 bytes, which is a reasonably strong pattern.) can anyone provide a magic number for .blend files? also, did anyone end up registering the MIME type "application/x-blender" with the IANA? even if not, is that the one we should use? thanks! - J _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers -------------------------------------------------------------------- myhosting.com - Premium Microsoft® Windows® and Linux web and application hosting - http://link.myhosting.com/myhosting _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
