When it comes to repair the most fundamental part of all is what is where and what does it do.

When we lose a file from a drive we usually get a bit stressed, and angry sometimes but things seem to be a bit easy, we have two option to recover the files using the usual methods either a recovery software or unhanding them from the drive the two methods work this way:
The deleted files
The deleted files are the ones deleted accidentally or intentionally with a malicious intent, so if things got this way the choice we have around is to use recovery software and look for the files in the drive as the only choice.
The second and most usually occurring to a lot of us is the virus issue, which hide files from our flash drives and many other file storage devices. The easy way is to use antivirus software with the option to get back the files or use command promote (CMD) an old UI/OS for windows command line with the privilege of an administrator. So how is that done?
First open the CMD by typing CMD in the start button search area or by going to the RUN (Windows + R) option by typing the CMD will work.
Start >>All programs >>Accessories>> Command promote>>Right click >> run as Administrator (Best option).
Then when the CMD appear usually a black screen with texts only, then we type the following commands
The drive latter of the drive you are trying to recover from; then change the directory to it usually E: F: G: something like this.
Then typing this will eventually bring back your files from the hidden world
Attrib –s –h /d /s easy right?
We are not done yet, this command works usually if our system is not infected with the same virus causing it, so we now have to use another windows tool called the TASK MANAGER by pressing the Ctlr+Shift+Esc buttons on the key board then going to the PROCESSES tab and GOOGLING any unusual process names and ending the processes as well as deleting them from the folder they are located in(the usual caliper is the syswin32.exe) Trojan downloader which opens the back door for others like it. Mostly hiding itself in the directory
“C:\\Windows\system32\syswin32.exe”
GOOD LUCK!!!
