Hudl 2 windows 7?

Notwithstanding "Good Luck's" contribution, any transferred file should be seen in the file explorer, whether there is an application that can handle the file or not.

A quick Google search provides some interesting similar problems:

The $64,000 question: have you upgraded to Lollipop?

Whatever, it may still be worth posting in the above specialist Android forums.

This MAY be of some help:

You appear to be having problems sending files (a file) from one machine to another via a usb cable - each machine running Windows 7 - some files can be transferred successfully.

You ask for ideas.

All files have an extension such as .pdf meaning Portable Document Format or .txt meaning text or .doc meaning Microsoft Word.

You do not say the extension of your failing file and you do not say if there's an error message.

It may be that the file is actually transferred between the machines but that the receiving machine has no application that can handle (and display) the particular file.

That is my idea.

Using expressions such as b...dy and b...d does not improve your communication.

Good Luck...
