Portable Optima

Portable Optima is a small-sized software application that facilitates a simple solution to cleaning up disk space, by removing unnecessary or unused junk files. It comes loaded with a few cleanup options that can be figured out even by less experienced users.

No setup necessary

As the name of the program says, it's wrapped in a portable package, which means you can save its files anywhere on the HDD or on a removable storage unit, and directly launch Portable Optima on any computer you want to clean, whether it's at home or at work. It doesn't change Windows registry settings.

Remove unnecessary or unused files

The interface it adopts is not particularly attractive, yet neatly organized. It's possible to clean up temporary files, DLL and driver cache along with pre-compiled setup files in the Windows directory, as well as files in the My Documents and Recycle Bin locations.

Compress rarely used files and manage autostart apps

In addition, Portable Optima is capable of compressing rarely used files, giving you the possibility to specify the number of days to take into account for their age. It automatically put together a hierarchical view with large files that you can study, and lets you manage applications that automatically run at every Windows startup.
What's more, the utility provides shortcuts to several Windows features, like installed programs and other components, the Windows directory, and Program Files.

Evaluation and conclusion

We haven't come across any difficulties in our tests, thanks to the fact that Portable Optima didn't hang, crash or display error messages. It completed scan and cleanup jobs fast while remaining light on system resources consumption.
On the other hand, it doesn't come bundled with too many advanced settings. For example, it doesn't implement file filters or let you remove all items from custom locations. We must also keep in mind that Portable Optima hasn't been updated for a long time.
