How can we help?

Many Windows applications create junk files. Such files are normally deleted as soon as they become unnecessary, by the application that created them. However, they can remain on your hard drive if the program that created them was terminated unexpectedly or if it was not programmed to delete said files, or if there was a system crash, etc. Accumulation of junk files takes up disk space, and may also impact on system performance. Junk Files Cleaner lets you find and remove unnecessary files from your computer. You can select which drives to scan, and what type of file extension to scan for. The most common temporary and junk files extensions are built-in, but you can also add whatever extensions you wish. You can manually add a specific folder (Options -> Junk Files Cleaner -> Include), whose content will then be considered junk and will be removed at every scan. If you do not want to scan a whole drive, just select a specific folder. To do so, use the Scan Folder… button/text, just above the list of drives. As soon as you select a folder, the scanning will begin. Available commands for the Junk Files Cleaner:

• Scan – performs a scan with your current settings. A small window will appear while the scanning is in progress. You can cancel the scan by clicking the Cancel button, and you will be presented with a list of files found up until that point.
• Delete – deletes all found junk files that have a check mark, after the scan is completed or canceled.

Right clicking a junk file will bring up a context menu with the following commands:

• Open – opens the selected file, as if you have double clicked it.
• Search at Google for – use it to search online using Google for name of the selected file. This will open your default web browser and display the results of the search.
• Open containing folder – opens the folder containing the selected item in Windows Explorer.
• Properties – shows the file’s properties in Windows Explorer.
• Check all items – puts a check mark for all files in the list.
• Uncheck all items – removes the check marks for all files in the list.
• Check all selected items – puts a check mark for all selected files in the list.
• Uncheck all selected items – removes the check marks for all selected files in the list.

The On-Screen Keyboard can also be used as a temporary/emergency workaround, if you do not have a real keyboard for the moment but you need to be able to type.

5.3.8. DISK DEFRAGMENTER

Disk Defragmenter analyzes local volumes and consolidates fragmented files and folders so that each occupies a single, contiguous space on the volume. As a result, your system can access files and folders and save new ones more efficiently. By consolidating your files and folders, Disk Defragmenter also consolidates a volume’s free space, making it less likely that new files will be fragmented. The process of consolidating fragmented files and folders is called defragmentation. After defragmentation, your hard disk drive will be well arranged and your system will work faster.

The History Cleaner tool consists of three modules – Browsers Cleaner, Windows Cleaner, and Microsoft Office Cleaner. Each is accessible from a tab at the top of the main window of History Cleaner. Use the Clear button when a specific cleaner is active, or the Clear All button for all 3 cleaners combined.

• Browsers Cleaner – Your browser makes a detailed record of every web site you visit. A simple press of a button in your browser window lets anyone see what you have been browsing on the web. Temporary internet files include images, videos, audio files, etc., plus all the web pages you have visited. Browsers Cleaner erases web site history for the following browsers: Edge, Internet Explorer, Firefox, Google Chrome, and Opera. Deleting this history will also free up space on your hard disk.

  Check the desired options for the browser history you want to clean and then click the Clear or Clear All buttons in the Commands Panel. You can also check or uncheck all options for one or all browsers by right clicking, and selecting the appropriate setting.

• Windows Cleaner – Microsoft Windows keeps a history of the many things you do – see the options listed below. Windows Cleaner lets you remove this history easily and quickly. You can also empty your Recycle Bin, and delete temporary files, freeing up more disk space. Available options for Windows Cleaner are:
  • Clear Recent Documents History
  • Clear Start Menu Run History
  • Clear Find File History
  • Clear Printers, Computers and People Find History
  • Empty Clipboard
  • Clear “MS Paint” Recent Files History
  • Clear “MS WordPad” Recent Files History
  • Clear “Regedit” Last Opened Key History
  • Clear Common Dialog Open Save Recent Histry
  • Clear Common Dialog Last Visited Folder History
  • Empty Recycle Bin
  • Delete Windows Temporary Files
  • Delete Start Menu Click Logs
  • Delete crash memory dump files
  • Delete Chkdsk (Check Disk) recovered file fragments
  • Delete Thumbnail Cache.
  Check the desired options you want to clean and then click the Clear or Clear All buttons in the Commands Panel. You can also check or uncheck all options by right clicking and selecting the appropriate setting.
• Microsoft Office Cleaner – allows you to remove history of most recently used files in Microsoft Word, Excel, Access, and PowerPoint. If you do not want somebody else to see your last opened or edited documents, spreadsheets, or other files created using Microsoft Office, just select those, and click the Clear or Clear All button on the Commands Panel. Your most recently used files will no longer be listed. Windows also keeps a record of your recent files. Use Microsoft Windows Cleaner to clear them too. You can also quickly check or uncheck all options by right clicking, and selecting the appropriate option.

NOTE: Remember, the Clear All button will cleanse all 3 history modules in one go.

Deleting files and folders from the Recycle Bin does not mean that they are gone forever. They are simply marked as deleted but not physically erased. Your “deleted” data may be confidential, but can still be easily retrieved using standard recovery tools or undelete programs – even many years later.

Evidence Remover will eliminate any possibility of data retrieval from your hard drive(s). It will permanently erase previously “deleted” files and folders still left physically on your hard disk. No matter what recovery tool (free, professional, expensive, whatever) may be subsequently employed, the result will always be the same – data erased with Evidence Remover is impossible to recover.

To erase previously deleted files and folders, simply check the drive from which those files were deleted, then click the Execute button in the Commands Panel. Once started, you will see a window with a progress bar and the estimated time remaining for the operation. You have the option to Pause/Resume the process.

The process can be slow, because the data is randomly overwritten three times. The overall speed depends upon:

• your computer’s processor (CPU);
• the size of the selected drive;
• any running programs;
• any running security software – antivirus, Internet Security, etc.

During the process, the free disk space decreases because Evidence Remover creates a huge file, and writes random data in it. That huge file is deleted at the end of the process – the free disk space is restored.

As detailed in Evidence Remover, simply deleting files and emptying the Recycle Bin does not mean they are gone forever. Deleting files in Windows just means that they are marked as such, and the space allocated to them up until that point then becomes available for other use. This is because if Windows had to physically erase all deleted files, it would take a long time and slow down your computer. There are also many system, temporary, and other files which are unimportant so making them unrecoverable would be waste of resources. Unrecoverable Delete physically only erases those files and folders that you select, but will take longer than a simple Windows delete. So to securely delete your selected files and folders and be sure that no one, with any recovery tool (free, professional, expensive, whatever) will retrieve them, use Unrecoverable Delete. The result will always be the same – the erased data is impossible to recover. Unrecoverable Delete has the following commands:

• Add File(s) – use it to add a file or files that you want to erase forever.
• Add Folder – use it to add a folder that you want to erase forever. All files and sub-folders of the selected folder will be erased.
• Delete Forever – starts the erasing process. Once you start the procedure, you will see a window with a progress bar and the estimated remaining time of the operation. You will also have the option to Pause/Resume the process.

IMPORTANT: You can cancel the process but the files erased before cancellation will be unrecoverable, so please be careful when selecting the files and folders you want to erase.

The window of the Unrecoverable Delete tool supports drag and drop of files and folders. Because Revo Uninstaller has administrative privileges, programs with lower privileges cannot drop files and folders in it. For example, if you run Windows explorer or any other file manager with a standard user account (not as administrator), you will not be able to drag and drop files in Unrecoverable Delete tool.
