How to solve Folders Showing as Shortcuts, Hidden in USB/Memory-Card/HDD

By connecting flash drives to the affected computer, often it shows flash drive containing just some folder's shortcuts. Sometimes it shows nothing though drive's properties show it has files in it. Even we get some inaccessible folder or file. This type of problem may also seen in our local drives (HDD partitions). Even paid anti-virus is unable to resolve those folders, they just scan and detect The AUTORUN worm which one will execute all programs. Then our important files remain hidden.

Hidden folders and Shortcuts by the Autorun Worm

Here we will see how can we solve this problem by using command line and batch file. Though the batch file is nothing but the executable file contains command lines. So solving the hidden and shortcut problem of USB or drives, we must have the administrator privilege as we will execute something.

Using Command line:

To solve/fix the folder's hidden or system file, the easiest way is to run a command line. You can apply this command to USB and local drive as well, need to change the drive_letter.

Go to Run, type cmd and hit enter. In command prompt just type:

attrib -h -s -r -a /s /d drive_letter:\*.* 

And hit enter. Be sure you've typed the drive letter (e.g. j:,h: or D:) instead of "drive_letter" in the command line. My USB drive letter is J: and my command should looks like:

Command for unhide system-hidden files on a drive

All files and folders will be normal and you should be able to delete the shortcuts, created by the virus.

Command line details: Here atrib=attribute, "-"=remove attribute/permits, h=hidden s=system, r=read-only, a=archive, /s=sub directory, /d=directory, drive_letter=the letter of the drive shown in windows explorer (e.g. j:,h: or D:) and *.* is called the wild card for all files.

If you don't like to be a "command Ninja" then see below.

USB, MicroSD, MiniSD or other Mmory Cards issue:

     1. Connect your USB or memory card to the PC or laptop.

     2. Copy these lines and paste it into a "new text file"

@echo off

attrib -h -s -r -a /s /d drive_letter:\*.*

3. In the 3rd line give the drive letter name (Example: J or K or L etc.) instead of "drive_name"

4. Save the text file as any_name.bat

5. Double click on the any_name.bat file and it will run in the command prompt and see the hidden files/folders come back.

6. Delete the shortcuts and unnecessary files and folders from USB drive.

Local drive issue:

1. Copy these lines and paste it into a "new text file"

@echo off 

attrib -h -s -r -a /s /d D:\*.*

attrib -h -s -r -a /s /d E:\*.*

attrib -h -s -r -a /s /d F:\*.*

attrib -h -s -r -a /s /d G:\*.*

attrib -h -s -r -a /s /d H:\*.*

attrib -h -s -r -a /s /d I:\*.*

attrib -h -s -r -a /s /d J:\*.*

@echo complete.

2. Save the text file as a bat file (example: any_name.bat)

3. Run this bat file by double-clicking on it.

Thus you can solve this kind of problems with a *.bat file. You can save the *.bat file for solving this hidden problem.

Important: These tutorials are applied for Windows 7/Vista/xp. You must have the administrative privilege to run the command or execute the .bat file. Put the " : " after the j, k, or D (drive letters). These commands are not case sensitive.

sudo apt-get install qemu-kvm

Let's now create a virtual machine called android-4.0.img, you can rename it to whatever you want. The size for this virtual machine is 1GB, you can set it to any other value depending on the free space you have.
Create it now with this command:

qemu-img create ~/android-x86/android-4.0.img 1G

To start the installation, run these commands:

cd ~/android-x86/


kvm -m 512 -cdrom android-x86-4.0.iso -hda android-4.0.img -boot d

 Note: the -m 512 parameter is used to set the memory size for the virtual machine, you can adjust it to whatever you want.

In the fisrt screen, select " Installation - Install Android-x86 to harddisk" and press Enter:

In the next screen, select "Create/Modify partitions" and press Enter:

In the "cfdisk" screen, select "New" and press Enter:

How To Install Ubuntu 12.10 Using VirtualBox

 

If you want to test Ubuntu 12.10 (Quantal Quetzal) without bothering yourself in partitioning your hard drive or dual booting with another OS, you can use VirtualBox which allows to install multiple operating systems (Linux, Windows, Mac OS X, etc.) in your host machine. This tutorial will explain to you how to create a virtual machine and how to install Ubuntu 12.10 in it. These steps are also applicable on other Ubuntu versions (12.04/11.10, etc.).

If you are working on a host machine running Ubuntu, you can install the latest version of VirtualBox (version 4.2.0) with these commands:

echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

sudo apt-get update

sudo apt-get install virtualbox-4.2

For other operating systems, you can download the appropriate file from here. Also, you need to download the iso image of Ubuntu 12.10 from here .

Creating The Ubuntu VM (Virtual Machine)

Open VirtualBox and click New, then in the VM setup wizard, click Next and enter a name for your VM (Ubuntu 12.10 for example):

 

Note: Once you write "Ubuntu", the type of the OS will be detected automatically.

  In the next screen, select the RAM size you want to allocate for the VM in megabytes. In this example, we will keep default settings (512 MB):

In the next screen, keep "Start-up Disk" and "Create new hard disk" options selected, then click Next:

Select "VDI (VirtualBox Disk Image)" and click Next:

In this screen, you can choose any option, but it is recommended to select "Fixed size" because it will run faster with less errors:

Next, set the VM size, this depends on the free disk space you have on your physical hard drive (no less than 5GB):

Once your virtual machine is successfully created, right click it in the VM VirtualBox Manager and select "Settings":

Open the "Display" tab and check on "Enable 3D Acceleration," then click OK:
