How to delete all traces of a file?
Delete all traces of a file is a real secure deletion.
In Windows operating system, the function "delete" is redesigned, it is not completely delete a file but simply removes its references to speed up read and write efficiency while Windows is running, which is indeed very helpful when daily office job requires heavy data transferring. But it is also a chance for data theft to recovery sensitive files according to the traces that deleted files left. How to prevent data leaking? How to delete all traces of a file?
What about shift + delete?
Besides simply press the delete button on the keyboard, some geeks may have got used to the shortcut Shift + Delete to "permanently" delete files. But it is not actually "permanently", it is more like "temporally", because you can still get the deleted files back using Recuva immediately after you deleted them. There're no shortcuts to permanently delete a file but to overwrite the space with pointless zeros and ones, which is to zero filling or one filling those deleted files sectors again before data recovery program reaches them.
So, "shift + delete" is nothing more than just empty recycle bin operation; it has no meaning when coming to data safety. Erase, however, is the secure way to keep data safe.
How to delete all traces of a file?
To delete a file completely form a hard drive running Windows 10 (or other Windows OS), we can download data sanitization software ByebyeData Eraser to complete the job. Install the program and run it as administrator. You can run Eraser before you delete a file or after you deleted a file, Eraser has according plans to clean up traces.
Before delete a file:
1 In the sidebar of the main interface, click Erase files and folders, and then click the Add files button to add the file you want to permanently erase. Any file type can be added to Eraser's list, you can check the screenshot below to say the main stream file extension.
2Check the overwrite methods column, define how many passes you would like Eraser to adapt when erasing, you can choose between 1-35 passes, or from simple, advanced, complex and very complex overwrite methods. Frankly speaking, the 35 passes Perter Gutmann's method is quite time-consuming and has a very small range of usage in a very limited area. For most of us, the other 3 types of overwriting algorithms shall be the first option.
3 And then click Erase Now, then Eraser will need your final confirmation before it goes to operate. Click Yes to the require dialog and you'll have to say bye-bye to the file..
Now you can test the result by using some data recovery program to see if Eraser deleted all the traces of the file you added to Eraser's erasing list. You'll be impressed.
After deleted a file:
Since the file is already deleted, we don't have to use the Erase files and folders function any more, we just use another feature of ByebyeData Eraser instead:
1 Click Erase free space and select the drive the deleted file were stored. Note: the function Eraser free space is to erase all the free space, unused space and deleted space on the selected drive, not only will the files' trace be erased, but all the traces of all the deleted files will be erased at the same time. So please make sure there're no traces you need to recovery before you click start to erase.
2Specify a wiping method for the drive, since it is not a single file wipe, it is the entire drive erasing, time spend on this volume will be much longer than individual file wiping, you can run this operation at your spare time. Say, run it before you sleep and check the result when you wake up at morning.
3 Click Erase Now and YES to the confirm message..
ByebyeData can do more than just erase files folders and erase free space; you can see from the left nav bar, it is capable of more powerful function like erase the entire disk installed on Windows with a bootable media. It even erases all traces of the operating system.
