TeamViewer Portable

TeamViewer Portable can be used to share your desktop, handle other computers remotely, and send files. It can work behind any firewall or NAT proxy. You can join another computer by running TeamViewer on both of them. You don't have to install anything first. When both computers start up for the first time, partner IDs are made automatically. When you enter your partner's ID into TeamViewer Portable, the link is made right away. 

Features and High Points

Controlling a remote without setting it up 
Team Viewer lets you take control of any PC on the Internet from afar. You don't have to install anything; just run the app on both ends and join, even if your firewalls are very strong. 

Products, solutions, and services can be shown remotely. 
In the second mode, you can show your partner your screen. You can quickly show your demos, goods, and presentations on the Internet by streaming them live from your computer screen. 

Moving Files 
It has built-in file sharing that lets you send and receive files and folders from and to a remote partner. This feature works even when firewalls are in place. 

Works behind Firewalls 
Firewalls and closed ports, as well as NAT routing for local IP addresses, make it hard to use remote control software. You don't have to worry about security if you use the program; it will find a way to reach your partner. 

The highest level of security 
Team Viewer Portable is a very safe choice. The paid versions have fully protected data lines with key exchange and RC4 session encoding, which is the same level of security used by https://SSL. 

No Need for Installation 
You don't need to be an administrator to run Team Viewer. It's as easy as running the program... 

Very Good Performance 
It works best for both LAN and Internet links and chooses the best quality based on bandwidth, so it can be used effectively on any connection.
