Delete An "Undeletable" File

Delete An Undeletable File



  • Open a Command Prompt window and leave it open.


  • Close all open programs.
  • Click Start, Run and enter TASKMGR.EXE
  • Go to the Processes tab and End Process on Explorer.exe.
  • Leave Task Manager open.
  • Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in.
  • At the command prompt type DEL where is the file you wish to delete.
  • Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.
  • Close Task Manager.

Or you can try this


  • Open Notepad.exe

  • Click File>Save As..>locate the folder where your undeletable file is
  • Choose 'All files' from the file type box
  • click once on the file you wanna delete so its name appears in the 'filename' box put a " at the start and end of the filename (the filename should have the extension of the undeletable file so it will overwrite it)
  • click saveIt should ask u to overwrite the existing file, choose yes and u can delete it as normal

Here's a manual way of doing it

1. Start

2. Run

3. Type: command

4. To move into a directory type: cd c:\*** (The stars stand for your folder)

5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1

6. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.

7. Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.

mv- Change the Name of a Directory

Type mv followed by the current name of a directory and the new name of the directory.

 Example: mv testdir newnamedir

pwd - print working directory

will show you the full path to the directory you are currently in. This is very handy to use, especially when performing some of the other commands on this page

 rmdir - Remove an existing directory

 rm -r

Removes directories and files within the directories recursively.

chown - change file owner and group

Usage

chown [OPTION] OWNER[:[GROUP]] FILE

chown [OPTION] :GROUP FILE

Options

Change the owner and/or group of each FILE to OWNER and/or GROUP. With --reference, change the owner and group of each FILE to those of RFILE.

 -c, changes like verbose but report only when a change is made

 -dereference affect the referent of each symbolic link, rather than the symbolic link itself

 -h, no-dereference affect each symbolic link instead of any referenced file (useful only on systems that can         change the ownership of a symlink)

 -from=CURRENT_OWNER:CURRENT_GROUP

  change the owner and/or group of each file only if its current owner and/or group match those specified here.  Either  may  be  omitted,  in which case a match is not required for the omitted attribute.

-no-preserve-root do not treat `/' specially (the default)

-preserve-root fail to operate recursively on `/'

How To Install Linux Mint 16 In Dual Boot With Windows And Their Solutions

Guide To Install Linux Mint 16 In Dual Boot With Windows




     Last week I switched from Ubuntu 13.10 to Linux Mint 16 (which is also based on Ubuntu 13.10). For the sake of experimenting, I have been switching between Linux distributions quite frequently in recent times. I always dual boot Linux with Windows. As I leaned more towards Linux, I started using Windows less and less. In fact, now I hardly use it. But I just kept it as it is sort of back up if I screw up my system while playing with Linux. Dual booting Linux with Windows is always suggestible for the beginners. And in this article, I’ll show you how to install Linux Mint in dual boot with Windows. Once you have installed it, you can also check out things to do after installing Linux Mint 16.

     Before we proceed to see the procedure to dual boot Linux Mint 16 with Windows, let me give you some details. First, I had Windows 7 installed with 3 partitions on it. Later I installed Linux on it in dual boot mode. I changed the partition and kept around 100 GB of total 320 GB for Linux installation. In the course of time, I upgraded to Windows 8 and subsequently to Windows 8.1. I never had to face the problem of Windows 8's secure boot thingy. It is just to clarify that this process does not show you how to deal with UEFI.

Install Linux Mint 16 in dual boot with Windows 8:

     Follow the steps below to install Linux Mint in dual boot with Windows:

Step 1: Create a live USB or disk

    Download and create a live USB or DVD. If you are using Windows, you can use a live usb creator tool. In Ubuntu, you can use Startup Disk Creator (if it works).

Step 2: Boot in to live USB

     Plug the live USB or disk in to the computer and restart the computer. While booting the computer press F10 or F12 function key (defers from computer to computer) to go to the boot menu. Now, choose the option to boot from USB or Removable Media.

Step 3: Start the installation

     It takes some time to boot from the live USB or disk. Have some patience. Once it boots in to live disk, you’ll be provided to Try Linux Mint or Install Linux Mint. Even if you choose to try it, you can find the install option on the desktop:



     In next few screens, you’ll be asked to choose the language of the operating system. It will then do some checks on available space, battery and Internet connection.







Step 4: Prepare the partition

     This is the most important part of the whole installation. Where to install Linux Mint? As mentioned before, I prefer separate partitions for Windows and Linux. Windows is already installed here, we’ll prepare a new partition for Linux Mint. In the Installation Type window, choose Something Else:



     Now, I have 3 NTFS and some ext4 partitions. If you don’t have ext4 partition, don’t worry, we don’t need that. As you can see in the picture below, one of the NTFS partition consists of Windows installation. This should be untouched if you want to keep your Windows installation safe.

     I hope you have more than one NTFS (or FAT 32) partitions (i.e. Drives in Windows term) on your hard disk, with one of them consisting of Windows installation (usually C drive). What you need to do here is to delete a NTFS or existing ext4 partition and create some free space. This will delete all the data in that partition and this is why I asked you to verify if you have Windows installed in a different partition.

Click on the desired partition and press the - to delete the partition.




Step 5: Create root, swap and home

     Once you created free space on your hard drive, its time to install Linux Mint on it. Now, there are several ways to do it. But here, I’ll show you my favorite way and that is to have a Root, a Swap and a Home.

Create a root partition first. Choose the free space available and click on +.



Here, choose the size of root (10 GB is enough but I chose to have 20 here), choose ext4 file system, and mount point as / (i.e. root):



Now, next is to create swap partition. It is advised by many that Swap should be double of your RAM. You can choose the swap size accordingly.




The next step is to create Home. Try to allocate the maximum size to Home because this is where you’ll be downloading and keeping the files.



Once you have created Root, Swap and Home partitions, click on Install Now button.




Step 6: Follow the trivial instructions

     Technically, you have crossed the main hurdle if you react till this point successfully. Now you will be taken through a number of screens to select options like keyboard layout, login credentials etc. You don’t need to be a genius to figure out what to do here afterwards. I have attached screenshots for reference purpose here.












Once the installation is over, you will be presented with the option to keep trying live version or to restart the system.




And that would be it. On next boot, you will see the option of Linux Mint on the grub screen. And thus you can enjoy the beautiful and beginner friendly Linux distribution. I hope you found this guide to Linux Mint 16 dual boot with Windows helpful.

If you found this type of issues in Linux


  • Cannot boot into Linux Mint or Ubuntu after installing (dual-boot Windows)
  • Use EasyBCD click here to download torrent file
Bootloader tweaking utility EasyBCD makes dual booting between Windows, Linux, and even OS X an easy task, and the latest version updates with support for Windows 7 and newer Ubuntu versions with grub2.


You can see the list of booting options if u cannot find Linux in your partition option add it manually


Go to option Add New Entry click on Linux/BSD tab and change the drive to your Linux installation click Add Entry & follow the below instructions


After adding entry you can see the option in Edit Boot Menu Windows 7 & Linux and click on Save Settings and reboot.


If you found this type of issues in Windows

Method 1:

If you cannot Boot in to Windows after installing Linux Mint and you face this type of  issue

Disk Failure 
Ctrl + Alt + Delete to restart

Just insert your windows 7 DVD or USB then press shift + F10 it will open the command prompt

Simply type this commands:

bootrec /fixmbr

bootrec /fixboot

and finally you can boot in to Windows as well as Linux Mint

Method 2:

Another method to solve Windows Boot loader issue is Insert USB or DVD of Windows 7



Click Repair your computer

Go to the command prompt and follow the commands below.

       bootrec.exe /FixMbr

     If successful, you should be greeted with the message The operation completed successfully.  That's it!  Your Master Boot Record has been repaired.

     While the above command does fix the MBR, and sometimes that is enough, there still might be an error with the system partition's boot sector and Boot Configuration Data (BCD). This might occur if you have tried to install another operating system alongside Windows 7, such as Windows XP.  To write a new boot sector, try the following command:




        bootrec.exe /FixBoot 

     If you are still faced with your Windows 7 installation not being detected during start up, or if you wish to include more than one operating system choice to your system's boot list, you can try the following command to rebuild your BCD:
        
        bootrec.exe /RebuildBcd

     The above command will scan all your disks for other operating systems compatible with Windows 7 and allow you to add them to your system's boot list. 

Finally you got this boot screen after reboot.


Now you have Installed Dual Boot with Windows cheers...

How To Mount iPhone Or iPad With iOS 7 In Ubuntu 13.10/Linux Mint 16

How To Mount iPhone Or iPad With iOS 7 In Ubuntu 13.10/Linux Mint 16:

     I got an iPhone 5 with iOS 7 couple of months back. I tried to connect iPhone or iPad with Linux (Ubuntu and Linux Mint), it was recognized and it asked me whether I “trust this computer”?

     And I said “I do” and tapped on Trust. After a flash of seconds it asked me again if I “trust this computer”? And I tapped Trust again. And then it asked the same question, I felt like it got trapped in a while(true) loop. While at Ubuntu, it showed me that my iPhone was locked and I could not access any files on it:


     After some searching I came to know that this infinite loop of trust this computer with iOS 7 in Linux is a known bug.

     This actually is a new security feature in iOS 7 which aims to tackle the issue of fake iPhone chargers. So, what is the solution here? Is there a way to fix “trust this computer” with iOS 7 in Linux? libimobiledevice library is is expected to fix this issue in version 1.1.6 but there is no expected availability date for the stable version.

     Don’t be disheartened, you can still use the unstable version of libimobiledevice and connect your iPhone to Ubuntu easily. Let me show you how can you mount iPhone in Ubuntu 13.10 or Linux Mint 16 without getting in the pitfall of “trust this computer”.

Fix trust this computer issue with iOS 7 in Ubuntu 12.04:

     If you are using Ubuntu 12.04 LTS be it 32 bit or 64 bit or Linux Mint 13 Maya, you can add the following PPA by Ingo Haschler:

sudo apt-add-repository ppa:ingo/ios7support
sudo apt-get update
sudo apt-get upgrade

     This will upgrade the libimobiledevice (already installed on the system) to unstable version 1.6. Reboot your computer and try to connect iPhone with Ubuntu again. It should work now.

Note:

    If you get “lock down error”, try using the following commands:

sudo mkdir /var/lib/lockdown
sudo chmod 777 /var/lib/lockdown

Fix trust this computer issue with iOS 7 in Ubuntu 13.10:

     For seasoned Linux users, you can get the source code from the GitHub and compile it. For Ubuntu 13.10 64 bit and Linux Mint 16 64 bit users, there is a Debian package compiled for you by Iuri Diniz. You can download and install this .deb package to easily mount iPhone on Ubuntu 13.10 64 bit.


     Double click on the downloaded .deb file to install it. Note that Ubuntu and Linux Mint comes with libimobiledevice library pre-installed in it. This is why you would see an option of upgrading the libimobiledevice rather than installing it.


     Once installed, your iPhone or iPad should be mounted without any troubles. Here is a screenshot of my iPhone mounted in Ubuntu 13.10.


     I could access the files, transfer the files from Ubuntu to iPhone. It was recognized by Rythembox for synchronizing also. It is not the first time I had issues with connecting my mobile device with Ubuntu.

     I hope this quick tutorial solves the infinite loop of ‘trust this computer’ problem with iPhone and Ubuntu for you as well. In related problems, sometimes, Apple device don’t charge or charge slowly via USB, you can try iPad Charge to fix charging issues with Apple devices in Linux.
