Behind this API, it just adds a value to record the pending deleted files under the registry entry “”. So using Windows API MoveFileEx is an acceptable solution. This API can accept a parameter “ MOVEFILE_DELAY_UNTIL_REBOOT ” to remove the file only after reboot. In your case, you need check all process handler list to find which process locks this file and then close the handler via DLL injection. MessageBox.Show(exp.Message, 'Fatal error encountered', MessageBoxButtons.OK) MessageBox.Show(ex.Message, 'Error encountered', MessageBoxButtons.OK) ĭialogResult res=MessageBox.Show(str,'Potential hazardous operation',MessageBoxButtons.YesNo) ĭirectoryInfo adir = dir.GetDirectories() MessageBox.Show('Please select a drive to format.', 'Error', MessageBoxButtons.OK) ĭr = new = 'Drive:' + dr.Name + ' Drive Format:' + dr.DriveFormat + ' Available free space:' + dr.AvailableFreeSpace +' Formatting a drive will permanently DELETE all data in the drive'+' Do you want to continue?' Private void button4_Click(object sender, EventArgs e) MessageBox.Show('No such Directory exists at the specified path!') String list = Directory.GetFiles(source, '*.*')

Private void button3_Click(object sender, EventArgs e)ĭialogResult res = MessageBox.Show('Do you want to really perform this DELETION option?', 'Potential hazardous operation', MessageBoxButtons.YesNo) Private void button1_Click(object sender, EventArgs e)įolderBrowserDialog fd = new FolderBrowserDialog() Private void button2_Click(object sender, EventArgs e)

I have heard something regarding MoveFileEx api with the MOVEFILE_DELAY_UNTIL_REBOOT flag.What is the use of this and how to use it? Can any one suggest me some way to delete such locked files. I am having problem in deleting certain files and the folders.It throws an exception saying that its been used by some other program.I don't know which program is using it.

I am currently writing a small application in C# to learn how to handle files and folders in C#.
