As yet, Skype doesn’t offer an official portable USB version of their software (with the exception of the) which frustrates a lot of people (including myself). This has led people to make an unofficial hack of a portable version for themselves.
Read on to find out how to make skype portable. It’s extremely easy.
1. The first step is to make the folder on your USB stick where it will all stay. So call it whatever you want. Let’s call it “Portable Skype” for example. But you can give it whatever name you want (it can be ‘skype portable version’ or just skype, doesn’t matter).
2. Now go to the installed Skype app on your computer (normally located at C:\Program Files\Skype) and look for a file called Skype.exe
Right-click and copy that file. Do not move it anywhere. Just right-click and copy.
3. Now go to the “Portable Skype” folder and insert that copied “Skype.exe” file into the “Portable Skype” folder.
4. In the “Portable Skype” folder, make a new sub-folder called data
5. Inside the “data” folder, make a new text document using Notepad or something similar. Name the file skype.bat
6. Open this file up and insert the following line: skype.exe /datapath:”Data” /removable
7. Save and close the file. That’s it. You’re done. You now have a portable version of Skype.
I tested this by moving the whole lot onto a USB stick and then launching it from there. It launched immediately but the firewall asked me if I wanted to let it pass. So you would need to configure the firewall of the computer you would be using the portable Skype on to allow the app through.
There is an interesting thread on PortableApps about what should be put on the skype.bat file. If you want to fine-tune the file, you might want to read the thread.
This is just a “rough and ready” hack to put Skype on your USB stick and how to make skype portable app. Please note, future releases of Skype may cause this hack to stop working. I am hoping that Skype will eventually bring out an official portable version that works for ALL portable USB sticks, not just the U3.
