Great new application: Move and delete multiple copies

[m1234ike]

Hello DaniWeb,

I have a new idea for an app:

I have an external harddrive and I usually backup my desktop with a cleanup folder which I usually move to the external harddrive.

The problem is: when I search for a file (i.e. example.mp3) I will find multiple copies which are taking up way too much space.

Is there an app or some code that can search for an extension (i.e. .mp3)
and if it finds more than one copy of the same file, it can delete the extra file?

The reason I ask is: I have around 1300 different mp3s on my external harddrive and most of them are extra copies of the same mp3.
When I search for the extension mp3 and I want to move all of the mp3s to a single folder I am prompted way too many times for overwriting or keeping the same mp3 file.

I need an app that can force the move without prompting and delete the extra copies; so, I am left with only one copy of each.

i.e.

mp3 files on external hard drive for backup:
song.mp3 > in one folder
song.mp3 > in another folder
song.mp3 > in another folder
song2.mp3 > in one folder
song2.mp3 > in another folder
etc...

I want to consolidate all my mp3s in one folder:
foldertomoveto/ song.mp3
foldertomoveto/song2.mp3

Below is start:

For Each foundFile As String In My.Computer.FileSystem.GetFiles( _
My.Computer.FileSystem.SpecialDirectories.MyDocuments, _
FileIO.SearchOption.SearchAllSubDirectories, "*. & textbox1.text.trim())

'HERE WILL BE AN IF STATEMENT TO VALIDATE IF THERE IS MORE THAN ONE MP3 (ETC...) FILE
'WHICH WILL DELETE THE MULTIPLE COPIES AND KEEP ONLY ONE
'I MIGHT NEED A CHECKEDLIST BOX TO VALIDATE

Dim foundFileInfo As New System.IO.FileInfo(foundFile)
My.Computer.FileSystem.MoveFile(foundFile, "C:\StorageDir\" & foundFileInfo.Name)
Next

The other copies have been deleted.
Any hints?

Thanks in advance,

‘Hello Daniweb,
I am having some trouble determining how to use a checkedlistbox, add all files from the subdirectories with a common extension, and then check one of each similar files.
i.e.
checkedlistbox contains:
C:/song.mp3 <<<

1.Button andAlso you will need to set your "Original" Folder.Path.

    Private Sub moveFiles(ByVal selOriginalLocationFolder As String, ByVal selDestinationFolder As String)
        If Directory.Exists(selOriginalLocationFolder) Then
            If Not Directory.Exists(selDestinationFolder) Then Directory.CreateDirectory(selDestinationFolder)
            Dim iMoved As Integer = 0, iDeleted As Integer = 0
            With My.Computer.FileSystem
                For Each foundFile As String In .GetFiles(myOriginalFilesFolder, FileIO.SearchOption.SearchAllSubDirectories, "*")
                    '// check if File already.Exists in Destination.Folder
                    If Not File.Exists(selDestinationFolder & Path.GetFileName(foundFile)) Then
                        .MoveFile(foundFile, selDestinationFolder & Path.GetFileName(foundFile))
                        iMoved += 1
                    Else '// If it Exists in Destination.Folder, .Delete from Original.Folder.

Thanks Codeorder,

I have most of the code together with: 2 buttons (1 to get the files by the extension and the other for moving copying or deleting) , 2 textboxes (1 for the extension and the other for the path), 3 radiobuttons (move copy or delete), a checkedlistbox (to list the files), and a combobox (to select rename or overwrite).

With the combobox, the user can select to rename the files if the files in the destination path are the same name (getfilename) as in the source path or if there is more than one of the same file name (getfilename) in the checkedlistbox.

The only problem I have now is renaming: Do you or does anybody know a Windows-Like algorithm to "rename" similar files pf similar file names being moved or copied into the new directory?

i.e. In my case the user will initially select to rename all the similar files via selecting "rename" from the combobox, but: in Windows 7 the user is prompted with something like: "Keep both files". If the user selects this option the next similar named file will have an incremented number appended to the file name:

newfolder/song.mp3
newfolder/song(1).mp3
newfolder/song(2).mp3

In my case: if the user selects "rename" then no files will be overwritten.
The reason for this is if the user names two files the same name but the contents are different.

What I have so far is something like:

If My.,Computer.fileexists(foundfile)
For
‘some kind of for loop like
for each found2 as string in checkedlistbox1.checkeditems
if system.io.path.getfilename(found2) = system.io.path.getfilename(foundfile) and then etc…
dim s as string = “”
dim i as integer = 1
‘for loop of some sort etc..

S = (I + 1).tostring()
i = i + 1

next

My.computer.filesystem.movefile(foundfile, mypath & “\” & system.io.path.getfilenamewithoutextension(foundfile) & “(“ & s & “)” & system.io.path.getfilextension(foundfile))

I think the movefile naming convention above is correct but I need the right algorithm to name each similar file listed in the checkedlistbox1.checkeditems that are being copied or moved to a similar folder and renamed.

I WANT TO USE A CHECKEDLISTBOX BUT: the problem is when you sort the files they sort via path and not file name (getfilename). So, the index is also not sorted.

Any hints?

Thanks in advance,

Thanx,

Hello Codeorder,

How can I assign the following to your "Private arDummyFiles() As String" array?

For Each foundFile As String In My.Computer.FileSystem.GetFiles( _
My.Computer.FileSystem.CurrentDirectory, _
FileIO.SearchOption.SearchAllSubDirectories, "*." & TextBox1.Text.Trim())

I want to use a textbox to specify a certain pattern: i.e. ".*txt" files.
Then I want to either move, copy, or delete the files.
If the files file name (system.io.path.getfilename(foundfile)) is the same in the destination path and in the source path or if the there are more than one of the same file names on the list (getfilename) or both:
then they must be renamed by incrementing the end of the file:
i.e.

C:/Desktop/folderone/song.mp3
C:/Desktop/folder/song.mp3

After the move:

C:/Desktop/newfolder/song.mp3
C:/Desktop/newfolder/song(1).mp3

Any hints?

Thanks in advance,

>>How can I assign the following to your "Private arDummyFiles() As String" array?
Instead of looping thru the Dummy.Array in loadFilesToArrayLis , loop thru your For/Next loop that locates the Files and add the founFile to the ArrayList.

Regarding If File.Exists Then .Rename, I'll get back to you in a little while.:)

Took a lot less.time to do than expected, even took a sh.t in the .Process.Start(xD).

Hello Codeorder and Daniweb,

The project is almost complete the moved files can be renamed, but while debugging, when I select the "OVERWRITE" option to overwrite similar existing files a permissions error pops up. The message says that I do not have sufficient permissions.

i.e. C:/Cleanup/Music/rednation.mp3
...Desktop/rednation.mp3
The code for overwriting the files looks like this:

My.Computer.FileSystem.MoveFile(foundFile, myPathfour & "/" & IO.Path.GetFileName(foundFile), True)

I tried modifying the app.manifest by changing the line:

to:

and it did not work.

I also tried changing the ClickOnce security settings but no dice.

Any hints?

Thanks in advance,

Hello CodeOrder and Daniweb,

Thanx for your help. I can now successfully move and rename the files from my Desktop to my Cleanup folder.

However, I cannot overwrite certain files in the Cleanup folder even when the files are not in use.

When I try to move certain files from my Desktop to my Cleanup folder but an error message shows up while debugging saying: that I do not sufficient permissions.

Here is the modified code with a Try/Catch:

For Each foundFile As String In My.Computer.FileSystem.GetFiles _
(My.Computer.FileSystem.SpecialDirectories.Desktop, _
FileIO.SearchOption.SearchTopLevelOnly, "*.mp3")
Try
If My.Computer.FileSystem.FileExists(foundFile) Then

My.Computer.FileSystem.MoveFile(foundFile, myPathfour & "/" & IO.Path.GetFileName(foundFile), True)

End If
Catch ex As Exception
MsgBox("Error: " & vbNewLine & "The found file: " & IO.Path.GetFileName(foundFile) & vbNewLine & "cannot overwrite its matching file in the Cleanup folder. " & vbNewLine & "You do not have sufficient permissions to overwrite the file. " & vbNewLine & "Please close the file and try again OR " & vbNewLine & "you can select the RENAME option and rename the file.")
End Try

Next

'___________________________________________________________

I want to able to override the permission problems and simply overwrite the file in the Cleanup folder.

I tried to modify the app.manifest by changing the requested Permissions code to:

but it returns a ClickOnce error.

Any hints?

Thanks in advance,

I have not bothered with

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

, thus I have no idea regarding it.
I do however have an idea of my own.
.Why Not delete the File and Then .Move the File to the deleted File's location, instead of over.writing it?
