How to get permission for directly writing files to SD card from a PC I need to manage my Android's files from PC with my mouse and keyboard, instead of do it on 5" and 7" touch screens. I did many tries with Google, but all options lead me to only one way:


From the PC, write the file to internal storage, (ex: Xender)
From Android, using an Android file manager (for example, ES File Explorer) to cut &amp; paste the files to folders I want on the SD card.


The question is: "How do I set permissions to directly write to the SD card from a PC?"

I'm using Samsung Core Prime with Android 4.4.x (KitKat) and my PC's OS is Windows 7 64-bit.

Update:
I want to do it through Wi-Fi whenever I need instead of using a USB cable.
Below is a screenshot for clarifying my question:



Update:

Not only Xender, even ES Explorer can not write to extSDcard. Screenshot from my phone:

First of all, I'm not on Kitkat, but on Lollipop, just in case...

You can copy files from you PC to your phone through Xender, it works perfectly.

But first you must get rid of the annoying message in web.xender.com (that you are showing in your picture).

In fact you must do the authorisation process in Xender ON YOUR PHONE, you can't do it in your PC's browser.


To do this, simply launch Xender on your phone, and go to Settings.
Then in the first Menu, set the destination to SD Card. It will ask you to choose which Folder you want to point at. 
Simply choose SD Card, so all subfolders will be then authorized to work with Xender.


And voilà, you can now copy files directly from your PC to your SD Card, through Wifi and without any cable connection, and it's blazingly fast :-)
