I wanted to install Clipmate on a USB drive thinking that I could have a completely different database than the clipmate on my PC. IN the instructions it said to installed portable apps before installing the usb version of clipmate.
What I wanted clipmate to do isn't working so I want to uninstall it and since I only used portable apps to install the ortable clipmate I would like to uninstall each on the usb drive.
Is it as easy as deleting the things on the USb drive that were added or is there a clean uninstall process for both portable apps and portable clipmate?
You will find the instructions here: https://portableapps.com/support
If you read all of that you have much better insight into Portable apps and how to use them.
Use Portable Apps on both Flash Drive and HDD/SSD.
Also not that anycopy of Clipmate that you've obtained was not from here, as that's not one of the many programs we have available.
As for removing the PortableApps platform itself, simply deleting it is sufficient as it is self-contained.
