We're saving some additional metadata with Files that we'd like to update from our UI. Is there anything like a File.save(file)? Didn't see anything. Do we have to re-upload the file and write BL to handle the merging of the two? Seems like Kinvey would create a new file which isn't quite what we want.



Thanks!

The best way to do this is use BL to update the `_blob`collection using the [collection access module](http://devcenter.kinvey.com/reference/business-logic/reference.html#collection-access-module). Otherwise, you’d indeed have to re-upload the file.
