HOW TO: Locate using nested loop the biggest file in ("c:\")

[gflor16]

Here is the sample code:

For Each strFile As String In My.Computer.FileSystem.GetFiles("c:\")
lstData.Items.Add(strFile)
If strFile.ToString.StartsWith("c:\IO") Then
MessageBox.Show(strFile & " is in the root!")
Exit For

End If
Next
End Sub

What can I change in that code to look up for the biggest file on the root.

Thanks,

Here you go:

Imports System.IO

Dim DirInfo As DirectoryInfo
Dim Files() As FileInfo
Dim OneFile As FileInfo
Dim LargestSize As Long
Dim LargestFile As String
 
LargestSize = -1
LargestFile = ""
DirInfo = New DirectoryInfo("C:\")
Files = DirInfo.GetFiles("*.*", IO.SearchOption.TopDirectoryOnly)
For Each OneFile In Files
  If OneFile.Length > LargestSize Then
    LargestSize = OneFile.Length
    LargestFile = OneFile.FullName
  End If
Next
If LargestSize > -1 Then
  MessageBox.Show("Largest file is:'" & LargestFile & "' with size of " & LargestSize & " bytes", "Largest File", MessageBoxButtons.OK, MessageBoxIcon.Information)
Else
  MessageBox.Show("No files found in C:\", "Largest File", MessageBoxButtons.OK, MessageBoxIcon.Warning)
End If

No nested loops used...
