I made this script based on past answers from superuser, but now need to only archive specific file types. I messed around trying to use wildcards but nothing I tried seemed to stick.

If I wanted to change this script to filter by specific file-types instead of all file system objects, what needs to be changed and how? For example, if I wanted to only archive DLL files, or DLL & EXE files, how would it be changed?

'To use this at command-line, call `CScript.exe zip_it.vbs SourceDirectory PathToOutputZipFileIncludingDotZipExt`

Set parameters = WScript.Arguments

Set FS = CreateObject("Scripting.FileSystemObject")

SourceDir = FS.GetAbsolutePathName(parameters(0))

ZipFile = FS.GetAbsolutePathName(parameters(1))

CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)

Set shell = CreateObject("Shell.Application")

Set source_objects = shell.NameSpace(SourceDir).Items

shell.NameSpace(ZipFile).CopyHere(source_objects)

wScript.Sleep 400

You can use a filter. The magic is here:

SHCONTF_NONFOLDERS = 64

colFolderItems.Filter SHCONTF_NONFOLDERS, "*.ext"

Here it is in context with your code:

'To use this at command-line, call `CScript.exe zip_it.vbs SourceDirectory PathToOutputZipFileIncludingDotZipExt "file.pattern"`

Set parameters = WScript.Arguments

Set FS = CreateObject("Scripting.FileSystemObject")

SourceDir = FS.GetAbsolutePathName(parameters(0))

ZipFile = FS.GetAbsolutePathName(parameters(1))

FileFilter = parameters(2)

CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)

Set shell = CreateObject("Shell.Application")

Set source_objects = shell.NameSpace(SourceDir).Items

SHCONTF_NONFOLDERS = 64

source_objects.Filter SHCONTF_NONFOLDERS, FileFilter

shell.NameSpace(ZipFile).CopyHere(source_objects)

wScript.Sleep 400

This can be called with "*.txt" to select only text files, or "*.exe" to collect only exe files. Also note that it doesn't play well if there is no file filter included.

However, your code is designed to recreate the ZIP each time, so you'd need to test for the existence of the file first if you want to call repeatedly for additional file types. This change does that:

If Not FS.FileExists (ZipFile) Then

    CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)

End If

This does have a side-effect of popping (and almost immediately hiding) an overwrite prompt if the files already exist in the zip file. With that change you could do this:

cscript //nologo zip_it.vbs thefolder thefile.zip "*.txt"

cscript //nologo zip_it.vbs thefolder thefile.zip "*.doc"

It could be changed to iterate file types or extensions and collect all files if there is no filter, as so:

'To use this at command-line, call `CScript.exe zip_it.vbs SourceDirectory PathToOutputZipFileIncludingDotZipExt "file.pattern" "file2.pattern"`

Set parameters = WScript.Arguments

Set FS = CreateObject("Scripting.FileSystemObject")

SourceDir = FS.GetAbsolutePathName(parameters(0))

ZipFile = FS.GetAbsolutePathName(parameters(1))

SHCONTF_NONFOLDERS = 64



If Not FS.FileExists (ZipFile) Then

    CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)

End If



Set shell = CreateObject("Shell.Application")



If parameters.Count > 2 Then

    For lParams = 2 to (parameters.Count-1)

        FileFilter = parameters(lParams)

        Set source_objects = shell.NameSpace(SourceDir).Items

        source_objects.Filter SHCONTF_NONFOLDERS, FileFilter

        shell.NameSpace(ZipFile).CopyHere(source_objects)

        wScript.Sleep 400

    Next

Else

    Set source_objects = shell.NameSpace(SourceDir).Items

    shell.NameSpace(ZipFile).CopyHere(source_objects)

    wScript.Sleep 400

End If

This could be called like:

cscript //nologo zip_it.vbs thefolder thefile.zip "*.doc" "*.txt"
