How to use vbs to realize zip function
Editor to share with you how to use vbs to achieve zip function, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
Compression:
Function fZip (sSourceFolder,sTargetZIPFile)
'This function will add all of the files in a source folder to a ZIP file
'using Windows' native folder ZIP capability.
Dim oShellApp, oFSO, iErr, sErrSource, sErrDescription
Set oShellApp = CreateObject ("Shell.Application")
Set oFSO = CreateObject ("Scripting.FileSystemObject")
'The source folder needs to have a\ on the End
If Right (sSourceFolder,1) "\" Then sSourceFolder = sSourceFolder & "\"
On Error Resume Next
'If a target ZIP exists already, delete it
If oFSO.FileExists (sTargetZIPFile) Then oFSO.DeleteFile sTargetZIPFile,True
IErr = Err.Number
SErrSource = Err.Source
SErrDescription = Err.Description
On Error GoTo 0
If iErr 0 Then
FZip = Array (iErr,sErrSource,sErrDescription)
Exit Function
End If
On Error Resume Next
'Write the fileheader for a blank zipfile.
OFSO.OpenTextFile (sTargetZIPFile, 2, True). Write "Competition" & Chr (5) & Chr (6) & String (18, Chr (0))
IErr = Err.Number
SErrSource = Err.Source
SErrDescription = Err.Description
On Error GoTo 0
If iErr 0 Then
FZip = Array (iErr,sErrSource,sErrDescription)
Exit Function
End If
On Error Resume Next
'Start copying files into the zip from the source folder.
OShellApp.NameSpace (sTargetZIPFile). CopyHere oShellApp.NameSpace (sSourceFolder). Items
IErr = Err.Number
SErrSource = Err.Source
SErrDescription = Err.Description
On Error GoTo 0
If iErr 0 Then
FZip = Array (iErr,sErrSource,sErrDescription)
Exit Function
End If
'Because the copying occurs in a separate process, the script will just continue. Run a DO...LOOP to prevent the function
'from exiting until the file is finished zipping.
Do Until oShellApp.NameSpace (sTargetZIPFile). Items.Count = oShellApp.NameSpace (sSourceFolder). Items.Count
If WScript.Sleep 1500s is not successful, increase the number of seconds.
Loop
FZip = Array (0, ",")
End Function
Call fZip ("C:\ vbs", "c:\ vbs.zip")
Unzip:
Function fUnzip (sZipFile,sTargetFolder)
'Create the Shell.Application object
Dim oShellApp:Set oShellApp = CreateObject ("Shell.Application")
'Create the File System object
Dim oFSO:Set oFSO = CreateObject ("Scripting.FileSystemObject")
'Create the target folder if it isn't already there
If Not oFSO.FolderExists (sTargetFolder) Then oFSO.CreateFolder sTargetFolder
'Extract the files from the zip into the folder
OShellApp.NameSpace (sTargetFolder). CopyHere oShellApp.NameSpace (sZipFile). Items
'This is a seperate process, so the script would continue even if the unzipping is not done
'To prevent this, we run a DO...LOOP once a second checking to see if the number of files
'in the target folder equals the number of files in the zipfile. If so, we continue.
Do
WScript.Sleep 1000 'sometimes needs to be changed
Loop While oFSO.GetFolder (sTargetFolder). Files.Count < oShellApp.NameSpace (sZipFile). Items.Count
End Function
