In order to be able to copy / paste files through the clipboard, before connecting to a remote desktop, you need to set following settings (it needs to be done only once, settings will be saved in the future):
N.B.: These settings must be made on your computer, not on the server!
1. Click "Start" - "Run...":
1.1 If you do not have the button "Run..." in the "Start" menu so you can bring up the menu by pressing the combination Win + R (Win is the button with the Windows logo, usually located to the left of the spacebar, next to ctrl and alt).
1.2 In the window that appears, type mstsc.exe and click the "OK" button:
1.3 If you do not have the button "Run..." in the "Start" menu and the combination Win + R does not work either, then manually find and run the file c:windows system32mstsc.exe
2. In the launched RDP client, click the "Options" button
3. Go to the "Local resources" tab, check the "Clipboard" box in the "Local devices and resources" block, and then in the same place click the "Details" button.
4. Check the boxes for all local drives that will be used. Attention: you will be able to copy/paste files to the remote server only from the drives you select here.
Copying files between a computer and a server
Method 1: Copy and paste through the clipboard
You can copy/paste files between your computer and a remote server via the clipboard. Find on your computer the file or folder that you want to upload to the server, right-click on it and select "Copy" from the menu that appears. Then switch to the remote desktop, right-click on an empty space, and select "Paste" from the menu that appears.
Method 2: Copy via a connected drive
2.1 Launch explorer on the server (open any folder)
2.2 In the left menu select "Computer"
2.3 The list will contain the local drives of your computer that you have connected in the RDP client settings
You can copy and paste files from disc to the server and vice versa.
Attention: do not try to run programs directly from your local drive!
