Sometimes we forgot change our file to a available name. So the plugin can help you auto change your upload file. 
I will add a filetype option of setting in next version. 
And a rename popup before the file upload if you change setting in future, default value is post_name.

wp_upload_rename

Change upload filename to random characters / random numbers / date / other by yourself.

With the upgrade to WordPress 4.7.1, some non-image files fail to upload on certain server setups. This will be fixed in 4.7.3, see the <a href="https://core.trac.wordpress.org/ticket/39550" rel="nofollow ugc">Trac ticket</a>.
In the meantime, this plugin is a workaround that disables the recently introduced strict MIME check to restore the upload functionality.
Don’t forget to remove the plugin once WordPress 4.7.3 is available!

Disable Real MIME Check
