VacuumCleaner recognizes more than 2300 temporary files which take important space on hard drive. VacuumCleaner allows to delete this type of files: back-up's, reports, logs, event logs, language files (ex. Korean, Japan, China etc.) and also files that has not been deleted after uninstalling software, malwares and other not needed components in applications and Windows.
Updated signatures base assure that new not needed files are recognized and deleted !


Additionally VacuumCleaner has useful modules:

VacuumCleaner is designed for everyone who at least one time got problem with deleting of not needed files which just occupy free space on your hard drive. After installing it adviced to updated definitions of filter base.

On first run you can deleted from 500MB to even 1,5GB (it depends how big HDD you got)**. It will allow not only to get more free space but also speed up system and reduce hard drive defragmentation.
On next hard drive cleans result can vary from 200MB to 500MB **.

** - using clean with VacuumCleaner, QuickClean and Abandon Folders Monitor.

Big advantage is VacuumCleaner got the biggest not needed files base. Most of tested applications got only the most known not needed files.

When I create this app I tried to make VacuumCleaner most stable, fast and the most important - useful I give you guarantee that I don't put any harmful code into VacuumCleaner, and in it's modules which would destroy or spy your OS. About all founded bug in app and it's base I inform on webpage and via e-mail for all registered users.

OS and other applications create specific temporary files ex. tmp and you can delete them. You need to know than some application authors write their software which save important information needed to app run stable in tmp files. I mean that tmp extension is most of not neeed but some apps storage setting there. So this is why VacuumCleaner got Ignore list. This is why important thing is to check for update before scanning.

Signatures base are created using reports send by users and also with rules of new software tests and extension informations:

I cannot guarantee that you will delete good file (read need). But thanks to constant updates this situation is less risk.
Additionally VacuumCleaner creates back-up copies of deleted files so you can always restore if some error occurs.

For scanning I suggest 3 scan modes:

Safe mode and Safe mode (Express)
Assure deleting popular not needed files with big level of safety for OS and applications.

Medium mode and Medium mode (Express)
Assure deleting the most not needed files with good level of safety for OS and applications.

Advanced mode and Advanced mode (Express)
Allows to find the the most of not needed files but it should be used by advanced users only! In this mode risk of find "good" file is bigger than in Medium or Safe mode.

Modes (Express)
Found only new created files.

If you aware of deleting needed files even when you used safe mode, you can send scan results to analyze them. With that you will get your system scan results checked which you can safely delete in VacuumCleaner.

When you send scan results to analyze you not just get checked results but also you help in base updates.

I can't guarantee that VacuumCleaner will delete ALL temp files from your hard drive. Signatures base is constantly updated.
