Some programs allow a portable installation, that is an installation that does not really install anything within the operating system, but allows a certain software to be used.
Normally, when we go to install a program, the latter integrates completely with the operating system, going, therefore, to use even files already present in the computer, while a portable program is much leaner, everything that composes it is enclosed in a folder and do not touch anything else during installation.

Going into detail, when we start the installer for a normal program this happens:
– the software is saved in the program folder
-new libraries, useful to the program, are saved, so new DLL files could be added in the System32 folder

– new values are written in the registry

– various links inside the program are created
– depending on the choices, links are also created on the desktop, in Start and in the taskbar –
updates are easily installed via wizards
– when you uninstall (via the program-related uninstaller) one or more of the above items may remain on your computer

The programs installed by a normal installer are therefore better, since they are completely integrated with the system, they are faster than portable programs (both in startup and in execution) and are designed to work perfectly.
The problem is that, even if you have a program to uninstall them, when we go to uninstall them via Windows (starting the uninstaller created by the creator of the program) many files could remain within the system. From the point of view of privacy there are many possibilities that if someone checks if the software has been installed, he will be able to find out.
Before going on to the description of portable programs, we therefore clarify, as we have seen, that it is not so easy to move or copy already installed software, since it performs many operations before it can be used, so it is not possible to copy the written folder into programs and paste it where you want but you must always reinstall it.

The portable programs when installed instead carry out this:
-create a folder inside and copy everything you need to work

They do only one thing: creating a complete environment to work, where inside there is a simple executable file (.exe) to start it. Of course, they present the cons that we have seen before, but can be moved freely anywhere, even on USB sticks.
The big advantage, however, is that they do not install “really” because in fact if we want to delete them we only have to delete the folder where we decided to install it, since no other file is written in the system.

To find them on the Internet and download them, simply do a search by writing the name of the program with portable next to. If we created this type of installation we will find it quite easily. Once the package has been downloaded, all we have to do is start the wizard which will ask us where to save the program.
After the installation is complete, we have to open the folder and start the executable file. If we have to move it or copy it on a stick we can easily do it by copying the whole folder, and when we want to uninstall it we just have to delete the whole folder and empty the trash.
