Onedrive corrupted many software projects

Question

HELP! Microsoft onedrive has corrupted many files by changing the name from “myfile” to “myfile-DEKSTOP-7CC49LB”. This happened when I bought a new laptop, and signed in to my microsoft account with the new laptop. I then tried to access my onedrive folder and found out that all my projects where outdated. Then I had a look at my old laptop and found out onedrive was not synching anymore (probably has not been synching for months already) for unknown reasons. I reset onedrive on my old laptop and then it started uploading all the files that it had not uploaded for quite some time. And now I found out that a lot of file names have changed, and therefore a lot of my software projects have been corrupted.

Here’s the problem: I am a PLC software engineer. My software projects are stored in onedrive folders. When I want to open one of these projects with my application it gives me a bunch of errors because a lot of file names have been changed, so they cannot be found anymore.

Simply changing the names back from “myfile-DEKSTOP-7CC49LB” to “myfile” would not work, because:

• there are thousands, if not tens of thousands of files that have been renamed, manually editing them would take forever
• the original file “myfile” also still exists! This however is the old version that I would like to delete

Here is an example of a software project that cannot be opened anymore:

You can see for instance the following files:

MaeExp: this is a file belonging to the 'old' version of this software project

MaeExp-DEKSTOP-7CC49LB: this is the correct file, belonging to the newest version of this project. BUT the application cannot open this because it does not recoginze the name!

So what needs to happen is: the old file ( "MaeExp" in this example) needs to be deleted, and the "-DEKSTOP-7CC49LB" extension needs to be deleted (so that "MaeExp-DEKSTOP-7CC49LB" gets renamed to "MaeExp")

Answer 1

Unfortunately no support from microsoft for this issue. I have since resolved this by writing a visual basic app to automatically delete the old files, and rename the files with the '-DEKSTOP-7CC49LB' extension. Here is the code if someone else runs into the same problem:

Public Class Form1

    Dim CopyCtr As Long

    Private Sub BtnRename_Click(sender As Object, e As EventArgs) Handles BtnRename.Click

        Call LoopAllSubFolders("C:\Users\koen\Downloads")

        TxtBox.Text = CopyCtr & " copies found and renamed"

    End Sub

    Sub LoopAllSubFolders(ByVal folderPath As String)

        Dim fileName As String

        Dim fullFilePath As String

        Dim fullFilePathToDelete As String

        Dim newFileName As String

        Dim numFolders As Long

        Dim folders() As String

        Dim i As Long

        If folderPath.PadRight(1) <> "" Then

            folderPath &= ""

        End If

        fileName = Dir(folderPath & "*.*", vbDirectory)

        While Len(fileName) <> 0

            If fileName.PadLeft(1) <> "." Then

                fullFilePath = folderPath & fileName

                If (GetAttr(fullFilePath) And vbDirectory) = vbDirectory Then

                    ReDim Preserve folders(numFolders)

                    folders(numFolders) = fullFilePath

                    numFolders += 1

                Else

                    Debug.Print(fullFilePath)

                    If InStr(fileName, "-DESKTOP-7CC49LB") Then

                        newFileName = Replace(fileName, "-DESKTOP-7CC49LB", "")

                        fullFilePathToDelete = folderPath & newFileName

                        My.Computer.FileSystem.DeleteFile(fullFilePathToDelete)

                        My.Computer.FileSystem.RenameFile(fullFilePath, newFileName)

                        CopyCtr += 1

                    End If

                End If

            End If

            fileName = Dir()

        End While

        For i = 0 To numFolders - 1

            LoopAllSubFolders(folders(i))

        Next i

    End Sub

End Class

This worked perfectly and I can now access all my projects again.

Answer 2

I have not installed 365. I use office proffessional plus on both laptops.

Onedrive versions on both laptops are: 2022 (build 22.121.0605.0002) 64 bit

I was not notified on any onedrive synch inssues on the old laptop, it was just stuck on uploading files at 0kb/s. That's when I reset onedrive by entering the command %localappdata%\Microsoft*OneDrive**onedrive*.exe /reset

After this onedrive restarted again and started uploading all my work, but after that I discovered that a lot of files had been renamed with the "-DEKSTOP-7CC49LB" extension

Answer 3

You have failed to mention what 365 license type you had?

On the new PC you install 365 via the MS Account associated with MS Office

Nothing in OneDrive content would have changed

On the old pc you would have been notified on any OneDrive sync issues
