Delete Many Files In Application Data Folder - vb.net

I'm trying to delete 3 files (file1.sol file2.sol file3.sol)
from the Application Data folder. My code words just fine with one file, but how can I make it delete the three files?
Here is my code:
Private Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click
Dim path As String = System.Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
Dim fileList As New List(Of String)
GetAllAccessibleFiles(path, fileList)
Application.DoEvents()
Dim files As String() = fileList.ToArray
For Each s As String In fileList
My.Computer.FileSystem.DeleteFile(s)
Next
End Sub
Sub GetAllAccessibleFiles(ByVal path As String, ByVal filelist As List(Of String))
For Each file As String In Directory.GetFiles(path, "file1.sol")
filelist.Add(file)
Next
For Each file As String In Directory.GetFiles(path, "file2.sol")
filelist.Add(file)
Next
For Each file As String In Directory.GetFiles(path, "file3.sol")
filelist.Add(file)
Next
For Each dir As String In Directory.GetDirectories(path)
Try
GetAllAccessibleFiles(dir, filelist)
Catch ex As Exception
End Try
Next
End Sub

The first line in GetAllAccesibleFiles, is searching for files with the name: "file1.sol", that means it will only retrieve that file. Try "file*.sol" meaning it starts with "file" and ends with ".sol". That should work. If you only want to delete file1 ,2 ,and 3, not for example, file4, then you can run a for loop 3 times, check if "file1" exists, delete it, check if "file2" exists, and so on.

CopyFile isn't copying my file with the same extension?

I am trying to make it so my user can copy files from one folder to another folder, their playlist folder, so that they can use it throughout my program. So I tried this:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim result As DialogResult = MessageBox.Show("Are you sure you want to finish the playlist?", "Finish Playlist- WikiFinder", MessageBoxButtons.YesNo)
If (result = DialogResult.Yes) Then
For Each Item In ListBox1.Items
Dim str As String = IO.Path.Combine(MusicMenu.FolderBrowserDialog2.SelectedPath, "DONUTS")
My.Computer.FileSystem.CopyFile(Item.ToString(), str)
Next
Else
End If
End Sub
This works and makes the file, but the issue is I told it to copy an MP3 file and it just gave me a "File". Is there any way I can copy the file AND keep the original file's extension?
Since you pass only the directory to the CopyFile function, it creates a FILE.
Pass filename with Extension.
For Each Item In ListBox1.Items
Dim str As String = IO.Path.Combine(MusicMenu.FolderBrowserDialog2.SelectedPath, "DONUTS")
str = IO.Path.Combine(str,IO.Path.GetFileName(Item.ToString()))
My.Computer.FileSystem.CopyFile(Item.ToString(), str)
Next
Now the files will be copied to your DONUTS folder.

Directory.GetFiles - SearchOption.AllDirectories Does not give files in subfolders (vb)

Directory.GetFiles - SearchOption.AllDirectories Does not give files that are located in subfolders. I'm trying to copy al .jpg files from a usb to the computer but when files are located in sub-folders, it does not copy them.
Private Sub ButtonStart_Click(sender As Object, e As EventArgs) Handles ButtonStart.Click
Dim sourceDir As String = ComboBoxUsbSelect.Text
Dim backupDir As String = FileDestination
Try
Dim picList As String() = Directory.GetFiles(sourceDir, "*.jpg", SearchOption.AllDirectories)
' Copy picture files.
For Each f As String In picList
'Remove path from the file name.
Dim fName As String = f.Substring(sourceDir.Length)
' Use the Path.Combine method to safely append the file name to the path.
' Will overwrite if the destination file already exists.
If delete = False Then
File.Copy(Path.Combine(sourceDir, fName), Path.Combine(backupDir, fName), True)
Else
File.Move(Path.Combine(sourceDir, fName), Path.Combine(backupDir, fName))
End If
Next
Catch dirNotFound As DirectoryNotFoundException
Console.WriteLine(dirNotFound.Message)
End Try
MessageBox.Show("Done!")
End Sub

Files from sub directories

Can somebody help me to implement to add files from sub directories to my listbox ? I have looked for some information from google, but source code from those examples was really diffrent than my and I'm newbie in VB.NET. I think it may be the System.IO.SearchOption.AllDirectories but I have no clue how to implement it in my code.
Private Sub ButtonFolder_Click(sender As System.Object, e As System.EventArgs) Handles ButtonFolder.Click
FolderBrowserDialog1.ShowDialog()
FilePathLabel.Text = System.IO.Path.GetFileName(FolderBrowserDialog1.SelectedPath)
Dim folder As New IO.DirectoryInfo(System.IO.Path.GetFullPath(FolderBrowserDialog1.SelectedPath))
Dim arrfile() As IO.FileInfo
Dim file As IO.FileInfo
arrfile = folder.GetFiles("*.*")
dicPaths.Clear()
For Each file In arrfile
'ListBox1.Items.Add(file.FullName)
dicPaths.Add(file.Name, file.FullName)
Next file
For Each item As String In dicPaths.Keys
ListBox1.Items.Add(item)
Next item
Label1.Text = "Total Items : " + ListBox1.Items.Count.ToString
End Sub
Try This:
Public Function FindFiles(ByVal Path As String) As Boolean
Dim Directories As New IO.DirectoryInfo(Path)
Dim Directory As IO.DirectoryInfo
Dim File As IO.FileInfo
For Each Directory In Directories.GetDirectories
For Each File In Directory.GetFiles
ListBox1.Items.Add(File.Name)
Next
If Directory.GetDirectories.Length > 0 Then
FindFiles(Directory.FullName)
End If
Next
End Function
Usage: FindFiles(FolderBrowserDialog1.SelectedPath)

Copying files back to a Specific Folder

This program extracts files from a folder that has been modified today, and after the files are placed into another folder a batch file then deletes the rest of the non-modified files in that source folder.
The last thing my program is supposed to do is copy files from separate folder, and place them back into that source folder.
But my program only extracts the modified files, deletes the rest of the files in that folder, but when I run the program to also copy and place the new files into the source folder it just doesn't do it. Does anyone know why?
Imports System.IO
Public Class frmExtractionator
' Dim txtFiles1 As Control
Dim sourceDirectory As String = "F:\CopierFolderforTestDriveCapstone"
Dim archiveDirectory As String = "F:\FilesExtracted"
Dim originalDirectory As String = "F:\OriginalTestFiles"
Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
Try
Dim txtFiles = Directory.EnumerateFiles(sourceDirectory)
If (Not System.IO.Directory.Exists(archiveDirectory)) Then
System.IO.Directory.CreateDirectory(archiveDirectory)
End If
For Each currentFileLoc As String In txtFiles
Dim fileName = currentFileLoc.Substring(sourceDirectory.Length + 1)
If (IO.File.GetLastWriteTime(currentFileLoc).ToString("MM/dd/yyyy") = DateTime.Now.ToString("MM/dd/yyyy")) Then
MessageBox.Show(currentFileLoc & " moved", "Moved Succesfully")
File.Move(currentFileLoc, Path.Combine(archiveDirectory, fileName))
End If
Next
Catch eT As Exception
Console.WriteLine(eT.Message)
End Try
System.Diagnostics.Process.Start("F:\poop.bat")
Try
Dim txtFiles2 = Directory.EnumerateFiles(originalDirectory)
For Each currentFileLoc2 As String In txtFiles2
Dim fileName = currentFileLoc2.Substring(originalDirectory.Length + 1)
File.Move(currentFileLoc2, Path.Combine(sourceDirectory, fileName))
Next
Catch eT As Exception
Console.WriteLine(eT.Message)
End Try
End Sub
End Class
Change
Dim fileName = currentFileLoc2.Substring(originalDirectory.Length + 1)
to
Dim FileName = IO.Path.GetFileName(currentFileLoc2)

How to correctly enumerate files in selected path?

Visual Studio 2008 (vb.net)
I made simple anivirus but when I make Full scan by this code:
FolderBrowserDialog1.SelectedPath = ("C:\")
'first scan:************************************
Try
For Each strDir As String In
System.IO.Directory.GetDirectories(FolderBrowserDialog1.SelectedPath)
For Each strFile As String In System.IO.Directory.GetFiles(strDir)
ListBox1.Items.Add(strFile)
Next
Next
'Start the timer:
Catch ex As Exception
End Try
Timer1.Start()`
Just scan the first 6 files ...
I think the problem from Windows Folder permissions (Windows - Program Files ...etc)
So how to fix it?
Put a Console.WriteLine(ex) in your catch block so you can see any exceptions that are thrown. You'll probably see your problem then. Most likely permissions.
You could try the following:
For Each strFile As String In System.IO.Directory.GetFiles(strDir, "*", IO.SearchOption.AllDirectories)
Edit:
You could try the last solution found in this thread:
http://www.vbforums.com/showthread.php?t=624969
I tried this myself and it was super slow, but worked fine.
Public Class Form1
Private Sub foo(ByVal aDir As String)
Try
Dim di As New IO.DirectoryInfo(aDir)
Dim aryFiles() As IO.FileInfo = di.GetFiles("*.*")
Dim aryDirs() As IO.DirectoryInfo = di.GetDirectories()
For Each fi As IO.FileInfo In aryFiles
rslts.Add(fi.FullName)
Next
For Each d As IO.DirectoryInfo In aryDirs
foo(d.FullName)
Next
Catch ex As Exception
'Stop 'the catch should be more specific
End Try
End Sub
Dim rslts As List(Of String)
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
rslts = New List(Of String)
foo("C:\")
ListBox1.Items.Clear()
ListBox1.Items.AddRange(rslts.ToArray)
End Sub
End Class
It looks like your solution essentially loops through the first folder it can find and stops there. This solution is a bit different as it will recursively go through all the files and folders based on the start location.
