Answer 1

You can use MongoDB APIs for whatever programming language that you're familiar with.

Check out this: http://api.mongodb.com/

Answer 2

You can add files to GridFS within mongo by using mongofiles.exe from command line. ( https://docs.mongodb.com/v3.0/reference/program/mongofiles/ )

We can put a file within the GridFS store by running the following command and arguments

C:\mongodb\bin>mongofiles.exe put \temp\Music.mp3
2016-12-17T10:05:05.048+0000    connected to: localhost
added file: \temp\Music.mp3

We can then drop in to the mongo shell and see the file within the fs.files collection:

C:\mongodb\bin>mongo.exe
MongoDB shell version: 3.2.10
connecting to: test
> show collections
fs.chunks
fs.files
> db.fs.files.find().pretty()
{
        "_id" : ObjectId("58550dd18f96a237504521b3"),
        "chunkSize" : 261120,
        "uploadDate" : ISODate("2016-12-17T10:05:05.143Z"),
        "length" : 5386368,
        "md5" : "0ed99265aaf3a64ddf5df794e98b1cb3",
        "filename" : "\\temp\\Music.mp3"
}

MongoDB GridFS also allows you to add extra meta data on the file document and allows extra indexes too to allow you to easily search for documents.
