Erasing data (not rows) in specific rows in all files in a folder

[SandsB]

Yep - hundreds of files named "BlahBlahBlah 2021.xlsx"
I copied all of last year's files from a folder named 2020 into a new folder named 2021. I then renamed all the files to end with 2021 but....

Each file has 31 tabs and each of those tabs has data in rows 3 through 50 that need to be deleted so a macro (I wrote with the help of people here) can update the files with new data as it becomes available. I just need the files to be exactly as they are now but with no data in rows 3-50. I can't delete those rows because that would move other cells around - just need to delete the data and leave everything else as is.

If it matters, each of the files' 31 tabs are named for each day of the month (even February, April etc - don't ask). So the multiple files for January have tabs named 01-01, 01-02, 01-03, etc. And the multiple February files have tabs named 02-01, 02-02, 02-03, ...., 02-31.

How can I do a mass change to delete data (not rows) in rows 3-50 and change nothing else?

And for everybody reading this - happy new year and thanks to the many people who have been so helpful to me on this site.

Try this macro. Change the folder path (in red) to suit your needs.

Sub deleteRows()
    Application.ScreenUpdating = False
    Dim ws As Worksheet
    Dim directory As String
    directory = "C:\2021\"
    Set FSO = CreateObject("Scripting.FileSystemObject")
    Set folder = FSO.GetFolder(directory)
    For Each file In folder.Files
        Workbooks.Open directory & Application.PathSeparator & file.Name
        For Each ws In Sheets
           ws.Rows("3:50").ClearContents
        Next ws
        ActiveWorkbook.Close True
    Next file
    Application.ScreenUpdating = True
End Sub
