What is a RDP file?

Remote Desktop Protocol (RDP) is a Windows built-in remote access tool developed by Microsoft. The client, a computer that runs the RDP client software, connects to another computer that runs the RDP server software. The host computer generates an RDP file to contain the server's connection settings, and the client can create an RDP file shortcut so that the remote connection can be easily established by double-clicking on this file.

How to open and use a RDP file?

Usually, we can open a RDP file with Remote Desktop Connection. Then, let’s know more about how to create and use a RDP file.

Step 1. Search "Remote Desktop Connection" in the search box and then open it.

Bonus tip: What if you can’t open RDP file?

Sometimes we may meet with a series of problems when we open a RDP file, such as RDP file is corrupted or you can’t open RDP file. What we can do if we encounter the issue? Here let’s figure it out.

✐ Workaround: You can try to right-click on any RDP file and then click "Open with" > "Choose another app". Now select another program and check the box "Always use this app to open *.rdp files", which may easily get you out of trouble.

Method 1. Delete the connection file that can't be opened and re-create

For the reason that the connection file is corrupted, you can simply delete the corrupted connection file and recreate a new connection file by running RDP.

Step 1. Delete the RDP file on the desktop. After that, open This PC on the desktop, navigation: C:\Users\Administrator\Documents

Method 2. Edit the connection file

It seems that the problem with RDP being unable to open the connection file is related to the file signature. For this reason, you can republish the file without signing it and reset it, which will help resolve the issue.

Step 1. Navigation: C:\Users\Administrator\Documents

View Hidden Items

Step 2. Right-click on the connection file that cannot be opened, select open with notepad in the expanded menu, find the text starting with signscope:s:, and delete the entire line.

Step 3. Confirm Save and Exit, and double-click the RDP file again to see if the problem has been solved.
