Maybe this is good for the code.. Function parseZip with the name of the element isolated from the another names like .. '.mshp' or something with 4 or more chars

shp.parseZip = function(buffer, whiteList) { var key; buffer = toBuffer(buffer); var zip = unzip(buffer); var names = []; whiteList = whiteList || []; for (key in zip) { if (key.indexOf('__MACOSX') !== -1) { continue; } if (key.slice(-4).toLowerCase() === '.shp') { names.push(key.slice(0, -4)); zip[key.slice(0, -3) + key.slice(-3).toLowerCase()] = zip[key]; } else if (key.slice(-4).toLowerCase() === '.prj') { zip[key.slice(0, -3) + key.slice(-3).toLowerCase()] = proj4(zip[key]); } else if (key.slice(-5).toLowerCase() === '.json' || whiteList.indexOf(key.split('.').pop()) > -1) { names.push(key.slice(0, -3) + key.slice(-3).toLowerCase()); } else if (key.slice(-4).toLowerCase() === '.dbf' || key.slice(-4).toLowerCase() === '.cpg') { zip[key.slice(0, -3) + key.slice(-3).toLowerCase()] = zip[key]; } } if (!names.length) { throw new Error('no layers founds'); } var geojson = names.map(function(name) { var parsed, dbf; var lastDotIdx = name.lastIndexOf('.'); if (lastDotIdx > -1 && name.slice(lastDotIdx).indexOf('json') > -1) { parsed = JSON.parse(zip[name]); parsed.fileName = name.slice(0, lastDotIdx); } else if (whiteList.indexOf(name.slice(lastDotIdx + 1)) > -1) { parsed = zip[name]; parsed.fileName = name; } else { if (zip[name + '.dbf']) { dbf = parseDbf(zip[name + '.dbf'], zip[name + '.cpg']); } parsed = shp.combine([parseShp(zip[name + '.shp'], zip[name + '.prj']), dbf]); parsed.fileName = name; } return parsed; }); if (geojson.length === 1) { return geojson[0]; } else { return geojson; } };

um I don't know what you're suggesting here, if you are suggesting a code change, you can can just edit it on github and open a pull which will give me a better idea of what you actually changed
