Also, file recovery could be very useful after surviving a malware attack. This post covers how files are stored, how they are recovered, why they aren't deleted permanently by default, and how to permanently delete them.
First, it is important to know how your OS places files in your hard disks. Your files are saved on the hard disk in small pieces or chunks. Data chunks are usually scattered all over the memory architecture.
File Mangers of your Operating System keeps track of your files by knowing the addresses or links to all the chunks mentioned earlier. These are called inode numbers. When you delete a file, your OS simply removes the data it has stored about these links or inode values. What really happens when you delete a file is that the link is removed from the table in the File Manager System that's keeping track of the file.
From the explanation above, you'll observe that the data is still there. All that was tempered with are the links to the data they contain. Hard Disk Drives do not delete data, they simply overwrite them. Generally, recovery tools simply check for data without this inode values or links pointing to them on the disk in question.
These recovery tools make use of complex algorithms to create files with those small data chunks. If you've ever tried formatting your drive or USB flash, you'll notice that you were given two options; fast format and the slow format.
For fast format, only the inode links are removed while the OS rewrites all the blocks multiple times with random data in the case of a slow format. You may hit the delete button and think your file has been deleted from your device. Well, after deleting a file from your computer, it may go into the recycle bin because the dynamic link to the data was just erased —but not the data in memory.
If in the recycle bin, it could be viewed and easily restored from the recycle bin, i. So, what if a file is deleted from the recycle bin? Once a file is deleted from the recycle bin, you may think it is finally gone but actually, it isn't.
As said earlier, the link to the file's data is deleted. Files deleted from your computer can actually be recovered unless deleted with 'secure delete' tools.
Files are not actually opened directly but their inodes links to their data are the ones manipulated instead. The folder is usually somewhere in Program Files. You can delete every program that you have downloaded and installed. You can even delete pre-installed programs, but you have to be more careful with these because you could lose important functions on your computer.
Also, decluttering your software programs will ensure unnecessary data do not burden your computer. There are many excellent uninstall apps you can download for free and even purchase for your PC.
Some will work on Windows only or for macOS only, but others work well on both. Revo Uninstaller is an excellent option for Windows users, and aside from having a Pro version, you can download a free version as well.
CCleaner , a free version, and a Pro plan. Hopefully, you now have all you need to know about how to approach the removal of unnecessary programs from your computer. Sometimes, you might have to dig around to find leftover files or install a helpful uninstall software to perform the task more efficiently.
