As you may know, the File constructor support in Internet Explorer doesn’t exist. For security reasons, you may not be able to abstract the File object as you would like to do normally. It doesn’t if other Libraries that use the File API to upload files like the ng2-file-upload require it, it won’t work.

According to MDN Docs, the File interface provides information about files and allows JavaScript in a web page to access their content. A File object is a specific kind of a Blob, and can be used in any context that a Blob can. In particular, FileReaderURL.createObjectURL()createImageBitmap(), and XMLHttpRequest.send() accept both Blobs and Files.
