This does not appear to be a sketchup model require fix

@colin Please find my attached file which now says this does not appear to be a SketchUp model. Please help me. The attachment is too large to upload so i am sharing google drive link for downloading the skp file.
KALOOR HOSTEL.skp - Google Drive

That file is a lot of repeats of the same small amount of data. If you were to compress the file you would see that it comes out to about 1.3 MB. It isn’t in any way a SketchUp file.
