The drive will still be formatted, but all data will be erased. WARNING, this means the whole of the partition will be erased. Entire Drive will erase all of the files on the drive. Free Space Only will leave your personal files intact but will erase your deleted files.ī. Open CCleaner and click Tools then Drive Wiper. Method 2 (Manually wipe with Drive Wiper): Run CCleaner as usual by clicking Analyze then Run Cleaner. CCleaner displays a warning about extra time. Click the Windows tab, Scroll to bottom and select the Wipe Free Space check box. Open CCleaner, click the CCleaner icon at left if necessary. Method 1 (Automatically wipe when cleaning): Remember to delete any personal folders too. After saving your data you can then delete those files and finish by running Drive Wiper. Refer to my article in the April 2014 Guide & Digest “Moving Files from Windows XP to Windows 8.1”. If you are planning to dispose of your computer you may want to save your data files first. It’s best utilized when you are ready to dispose of your computer to prepare it for recycling. I don’t recommend that you use Drive Wiper as part of your normal monthly maintenance. For privacy and security reasons, you can set CCleaner to wipe the free areas of your hard disk so that deleted files can never be recovered. This means that, given the right software, someone could reconstruct all or parts of files that you’ve deleted. Over time, this data will be overwritten as Windows writes new files to that area of the drive. When you delete a file, Windows removes the reference to that file, but doesn’t delete the actual data that made up the file on your hard drive. Although the name sounds ominous it really is not a dangerous tool. One of the features built into CCleaner is called Drive Wiper. It’s use has been written about in my Guide and Digest articles and discussed at the PC Computer Club meetings. It is POSSIBLE that Ccleaner would refrain from purging all the *.Most of you have at least heard of CCleaner, the junk file cleaner program. If I include C:\Windows\System32\*.* for cleaning, "There is no way that Ccleaner could distinguish between junk and vital files on Flash drive"īut that would suggest I had more knowledge than the developers of Ccleaner, "BUT it may be reluctant to use its built in knowledge to FIND those junk files," I had in mind my 320 GB USB2 connected HARD drive with both FAT32 and NTFS partitions. My point 3 specifically refrained from referring to booting from a FLASH drive. I don't think it is possible to install your operating system in your USB flash drive. If the USB is small in size, especially if it doesn't have many folders and subfolders, its not hard navigating inside it and locating which files are no longer needed. It has this disk cleaner tool for all drives and you can use it to search for junk on the USB only but for multiple times, I tried to scan my USB with that disk cleaner tool, no junk files were ever detected. Well if you want a program that can supposedly search for junk files on the USB, there is a free program called Advanced System Care 3. The trick is, if you add a folder on the USB in the include list, how would you suppose that CCleaner will know which files are safe to delete inside those folders? It might end up deleting important files in your USB. Clicking the Add Folder button lets you browse in whatever location in the computer that you want CCleaner to clean and that includes USBs and even the folders inside those USBs. Just open CCleaner, go to Options, click the Include button and from there you can see the Add Folder and Add Files buttons. USBs use fast flash memories and by default, formatted as FAT or FAT32, not the standard NTFS on internal hard drives where you install the operating systems and besides, many USBs have far smaller capacities that hard disks and, lets say those only 1,2,4 and 8 GB in size.ĬCleaner does have an option to clear certain files and folders in the computer.
