This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
A DataGridView does not normally contain files, so you need to be clearer about what you hold in the DGV, where you get it from, and how you need to access it.
Use the "Improve question" widget to edit your question and provide better information.

stop downvoting idiot!
ask a real question first!

i still dont know what you want to do?!

are you reading a directory and adding all files to a dgv?
after that you deleting one file from the dgv but you execute the "scan-function" again and its there again?
sure... as long you dont delete it from file, or mark it as "do not read" it will be in the dgv all the time!

so what is your problem!?
and again! stop downvoting executeable code which is a working response to your "question"!

here a solution which should answer your question.
Important to prevent errors:
- setup the dgv selection mode to "selectFullRow"
- execute the FillGrid on program start
- add button to form with execute the BtnDeleteFileFromDgv on Click

C#

private void FillGrid()
{
	dataGridView1.Rows.Clear();

	if (!dataGridView1.Columns.Contains("fileName"))
		dataGridView1.Columns.Add("fileName", "File names");

	foreach (var file in Directory.GetFiles(@"c:\MyDir\"))
	{
		var index = dataGridView1.Rows.Add();
		dataGridView1.Rows[index].Cells["fileName"].Value = file;
	}
}
private void BtnDeleteFileFromDgv_Click(object sender, EventArgs e)
{
	if(dataGridView1.SelectedRows.Count == 0)
		return;

	var fileName = dataGridView1.SelectedRows[0].Cells["fileName"].Value.ToString();
	File.Delete(fileName);
	FillGrid();
}

if it is working, please dont forget to rate the post
