It often happens that while trying to delete a file or a folder, your system tells you that this particular file cannot be deleted at that time. These errors occur currently with video or music file formats. This can be due to a number of factors, such as:

• Someone else is accessing the file/folder on the network or on a shared computer
• You are trying to delete a system file that is being used by another program
• You are trying to delete an infected folder or your system has been infected and prevents you from deleting this file
• You have access restrictions on this particular file/folder
• The file/folder has been saved in “Read only” format
• Your system is not compatible with this kind of file and is hence displaying error messages.

Ensure that the file/folder is not in use

If you are using a shared computer, another user or program on the user’s account might be using the file/folder that you are trying to delete.
1. Ask the other user/s to close all the programs that they might be using
2. Make sure that they have log off from their account.
3. Restart your computer, log in to your account and try to delete the file/folder again.

Run your system on Safe Mode

If your system or the file has been infected by a virus, using the Safe Mode can allow you to delete it as most viruses get active while running the normal mode. Hence
1. Restart your system and when the first screen is displayed, press the F8 key on your keyboard.
2. Various booting options for your system should now be listed on the screen. Using your keyboard arrows, choose “Safe Mode”.
3. When the loading is done, choose the file/folder that has to be deleted, right-click on it and choose the “Delete” option.
4. Don’t forget to empty the Recycle Bin by right-clicking on the icon and choosing the option “Empty Recycle Bin”.

Use Notepad

You can try to use Notepad to open the file that you want to remove to bypass Windows Explorer and its indexing.
1. Open Notepad and go to the “File” and “Open” options
2. Ensure that the “File Type” option is set to “All files” and not only “Text documents”.
3. Once you have located the file that you want to delete, DO NOT double-click on it. Instead, use the right-click feature and choose “Delete” from the list.

Sir, just download & use the free software "deletedr" from the internet. It is a very useful software and can even delete files containing malwares etc.Good Luck.
