FileSystem.MoveFile - System.IO.IOException: The process cannot access the file because it is being used by another process.

Hello All;

I have a file move issue that only started because I had to take a sub-folder on my site, and [convert to Application]

Here is a portion of the code I am using.

            For Each postedFile As HttpPostedFile In filMyFile.PostedFiles
                Dim getfile As String = System.IO.Path.GetFileName(postedFile.FileName)
                Dim FileToMove As String
                Dim MoveLocation As String

                           GlobalVariables.savepath = Context.Server.MapPath("../Media/Temp/")
                           GlobalVariables.MovePath = Context.Server.MapPath("../Media/")


                            FileToMove = (GlobalVariables.savepath & getfile & ".mp3")
                            MoveLocation = (GlobalVariables.MovePath & strPath & "/" & getfile & ".mp3")


                            If System.IO.File.Exists(FileToMove) = True Then
                                My.Computer.FileSystem.MoveFile(FileToMove, MoveLocation) ' <<<< ERROR POINTS HERE
                            End If

Select all Open in new window

The code was working correctly until I changed the sub-folder to [convert to Application]
Once I did that, I received this error.

Permissions are correctly given for the folder, so it does not seem to be a permissions issue.
I used Windows Resource Monitor.
Chose the CPU tab.
Searched for mp3 in the [Associated Handles]
Here is one line from the results of the search

Image                PID      Type      Handle Name
w3wp.exe      12272      File             G:\InetPub\wwwroot\mysite\Media\Temp\03112020223702438.mp3

I read that I needed to close the opened file.
I tried to do.

mp3.Dispose() ' did nothing
filMyFile.Dispose() ' did nothing

Select all Open in new window

Any other suggestions to help get past this issue, so it will go back to working correctly?
Thanks.
