How Can I Delete All the .BAK Files in a Folder That Are More Than 7 Days Old?There are third party DOS utilities that can do date handling, but left alone, batch code is somewhat lacking in many features...date handling among them.

This little script should help you out:


Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.GetFolder("your foldergoeshere")
Set colSubFolders = f.SubFolders

For Each objFolder in colSubFolders
ShowFiles objFolder
Next

Sub ShowFiles(Fld)
Set k = fso.GetFolder(Fld)
Set s = k.SubFolders
Set kf = k.Files

For Each objFile In kf
If objFile.DateCreated < date - 7 Then
If objFile.Extension = "bak" Then
Wscript.Echo objFile & " " & objFile.DateCreated
End If
Next
End Sub


As written the script only lists files. Change the highlighted line to fso.DeleteFile(objFile). Be sure to change yourfoldergoeshere with something appropriate (ie: C:\Backup). Save the script with a vbs extension and run as cscript scriptname.vbs

I tried to modify your script as below but failed, COULD you help me to check. Thank you very much.

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.GetFolder("F:\test\backup")
Set colSubFolders = f.SubFolders

For Each objFolder in colSubFolders
ShowFiles objFolder
Next

Sub ShowFiles(Fld)
Set k = fso.GetFolder(Fld)
Set s = k.SubFolders
Set kf = k.Files

For Each objFile In kf
If objFile.DateCreated < date - 7 Then
If objFile.Extension = "bak" Then
fso.DeleteFile(objFile)
End If
End If
Next
End Sub

whosyourbuddy............. I may have inadvertently introducied a property that does not exist. On the other hand it would have been helpful had you pointed out the source of the error. In any case the ORIGINAL script was overwritten and used recursion to delete all bak files in the directory and it's subdirectories.

Code: [Select]Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.GetFolder("F:\test\backup")
Set colFiles = f.Files

For Each objFile in colFiles
If objFile.DateCreated < date - 7 Then
If Right(objFile.Name, 4) = ".bak" Then
fso.DeleteFile(objFile)
End If
End If
Next

Note : if "f:\test\backup" does not exist, the script will fail

Good luck. Does vbs is a freeware? Need to purchase license or not?No commercial license is needed. VBScript is installed on all WINDOWS MACHINES except the earlier versions of Win95. There are commercial editors available for VBScript but Notepad works just fine. The current version of the Windows Script Host (as it is officially known) is 5.6

There is a treasure of information about VBScript at the Script Center including free scripts, free downloads, online lessons and sample scripts for doing just about anything.

Good luck. I get the answer from website as below:

Set ObjFSO = CreateObject ("Scripting.FileSystemObject")

'Pull current date
DateInfo = Now

'Delete files older than X number of days
OlderThan = "7"

'Remove number of days from date
DateInfo = DateInfo - OlderThan

WScript.Echo "Deleting files older than " & DateInfo

'Folder we're interested in
strFolder = "F:\test"

'WScript.Echo DateInfo 'Testing


'Get folder for collection

NumberOfFiles = "0"
DeletedFiles = "0"

Set objFolder = objFSO.GetFolder(strFolder)
Set colFiles = objFolder.Files
For each objFile in colFiles
'WScript.Echo objFile.DateCreated 'Testing
'WScript.Echo objFile.Name 'Testing
NumberOfFiles = NumberOfFiles + 1
If objFile.DateCreated < DateInfo Then
WScript.Echo "Deleting " & objFile.Name
objFSO.DeleteFile(objFile.Path)
DeletedFiles = DeletedFiles + 1
End If
Next
WScript.Echo "Complete"
WScript. Echo NumberOfFiles & " file(s) in directory"
WScript.Echo DeletedFiles & " file(s) deleted"I'm glad the Scripting Guys were able to help. One nice thing is if you don't find a script to do exactly want you want, you can always borrow pieces of multiple scripts to satisfy your inner scriptwriter.

Unfortunately folks have been known to take this a bit too literally and built a frankenscript which turned their PC into a BRICK.
