File type is blank in Windows 7 and Windows 10

Using

<input type="file" ngf-select ng-model="uploadSelections.csvFile" />

whenever I look at $scope.uploadSelections.csvFile.type in Mac OS, it returns text/csv as expected.

However, in Windows (7 and 10 tested), running Chrome and IE11, $scope.uploadSelections.csvFile.type returns an empty string ''. The file object looks like this

File {}
  lastModified: 1450235407000
  lastModifiedDate: Tue Dec 15 2015 19:10:07 GMT-0800 (Pacific Standard Time)
  name: "filename.csv"
  size: 20524
  type: ""
  webkitRelativePath: ""
  __proto__: File

Any help would be appreciated.

File type property cannot be set programmatically so the best way is to have the check for file extension in the pattern.

Hello! I come from the future to tell you not to rely on filetype mime type when using FileList since on Windows this is blank.

Just had this exact same problem, commenting here since this is the only reference to this problem I’ve found online.

-                if (fileList[0].type === 'text/csv') {
+                if (/\.csv$/i.test(fileList[0].name)) {

Cheers!
