In my case: I want to keep a maximum of 7 files, and delete the oldest files if i have more then 7 files. I get an error on the HMI refferring to the fo.kill line in the script (see attachment). Does anyone know what to do? my code: Sub DeleteOldestFiles() Dim objFSO, objFolder, objFile, colFiles, OldestFile Dim FileName, FolderPath, FileLocation, FilesCount Dim fo Set objFSO = CreateObject("FileCtl.FileSystem") FolderPath = "\Storage Card SD\Logs\Archives\" Set fo = CreateObject("FileCtl.FileSystem") FileName = objFSO.Dir(FolderPath & "*.csv") OldestFile = FileName FilesCount = 0 While FileName <> "" If objFSO.FileDateTime(FolderPath & FileName) < objFSO.FileDateTime( FolderPath & OldestFile) Then OldestFile = FileName End If FilesCount = FilesCount + 1 FileName = objFSO.dir() Wend If FilesCount > 7 Then fo.kill (FolderPath & OldestFile) Oldest = OldestFile End If NmbrFiles = FilesCount End Sub Attachment IMG_20201021_153351.jpg (247 Downloads)

Does anyone know why it is created as "read only". Or how i can disable the "read only" status of the file using scripting?

Or fso.SetAttr PathName, 0 to set the file read/write. Beyer I figured out that it has to do with the "read only" status of the .csv file.
