我正在使用此代码将文件夹中的所有文件压缩到新创建的df.saveAsBigQueryTable("my-project:my_dataset.my_table")
文件中：
.zip只要我的目标文件夹与我的文件的文件夹不同，就可以正常运行。
但是当我尝试从文件夹中获取所有文件时，我遇到问题，将它们放入Dim FileNameZip, FolderName
Dim filename As String, DefPath As String
Dim oApp As Object
(defining all paths needed)
'Create empty Zip File
NewZip (FileNameZip)
Set oApp = CreateObject("Shell.Application")
'Copy the files to the compressed folder
oApp.Namespace(FileNameZip).CopyHere oApp.Namespace(FolderName).items
'Keep script waiting until Compressing is done
On Error Resume Next
Do Until oApp.Namespace(FileNameZip).items.Count = oApp.Namespace(FolderName).items.Count
Application.Wait (Now + TimeValue("0:00:01"))
Loop
并生成存档相同的文件夹 - 它会创建存档，然后尝试将其放入自身，这当然会失败。
我正在寻找一种方法来压缩文件夹中的所有文件，除了新创建的文件。
我在这里查看：https://msdn.microsoft.com/en-us/library/office/ff869597.aspx但这看起来非常特定于Outlook，我不知道如何将其应用到Windows文件夹。

不是一次添加所有文件（包括您创建的zip文件），而是使用FileSystemObject遍历文件，并在添加到zip之前将其名称与zip文件名进行比较：
Sub AddFilesToZip()
Dim fso As Object, zipFile As Object, objShell As Object
Dim fsoFolder As Object, fsoFile As Object
Dim timerStart As Single
Dim folderPath As String, zipName As String
folderPath = "C:\Users\darre\Desktop\New folder\" ' folder to zip
zipName = "myzipfile.zip" ' name of the zip file
Set fso = CreateObject("Scripting.FileSystemObject") ' create an fso to loop through the files
Set zipFile = fso.CreateTextFile(folderPath & zipName) ' create the zip file
zipFile.WriteLine Chr(80) & Chr(75) & Chr(5) & Chr(6) & String(18, 0)
zipFile.Close
Set objShell = CreateObject("Shell.Application")
Set fsoFolder = fso.GetFolder(folderPath)
For Each fsoFile In fsoFolder.Files ' loop through the files...
Debug.Print fsoFile.name
If fsoFile.name <> zipName Then ' and check it's not the zip file before adding them
objShell.Namespace("" & folderPath & zipName).CopyHere fsoFile.Path
timerStart = Timer
Do While Timer < timerStart + 2
Application.StatusBar = "Zipping, please wait..."
DoEvents
Loop
End If
Next
' clean up
Application.StatusBar = ""
Set fsoFile = Nothing
Set fsoFolder = Nothing
Set objShell = Nothing
Set zipFile = Nothing
Set fso = Nothing
MsgBox "Zipped", vbInformation
End Sub

我会在临时文件夹中创建zip文件，最后将其移动到目标文件夹。值得一提的两个注意事项：
1-循环方法直到项目计数在文件夹中相同且zip文件存在风险，因为如果单个项目的压缩失败，则会导致无限循环。因此，只要zip文件被shell锁定，就最好循环。
2-我将使用Shell的早期绑定，因为后期绑定Shell32.Application似乎在某些安装上存在问题。添加对Microsoft Shell Controls and Automation
Sub compressFolder(folderToCompress As String, targetZip As String)
If Len(Dir(targetZip)) > 0 Then Kill targetZip
' Create a temporary zip file in the temp folder
Dim tempZip As String: tempZip = Environ$("temp") & "\" & "tempzip1234.zip"
CreateObject("Scripting.FileSystemObject").CreateTextFile(tempZip, True).Write _
Chr$(80) & Chr$(75) & Chr$(5) & Chr$(6) & String(18, 0)
' compress the folder into the temporary zip file
With New Shell ' For late binding: With CreateObject("Shell32.Application")
.Namespace(tempZip).CopyHere .Namespace(folderToCompress).Items
End With
' Move the temp zip to target. Loop until the move succeeds. It won't
' succeed until the zip completes because zip file is locked by the shell
On Error Resume Next
Do Until Len(Dir(targetZip)) > 0
Application.Wait Now + TimeSerial(0, 0, 1)
Name tempZip As targetZip
Loop
End Sub
Sub someTest()
compressFolder "C:\SO\SOZip", "C:\SO\SOZip\Test.zip"
End Sub

我发现在没有第三方工具的情况下通过VBA进行压缩很难控制，下面可能不是直接的答案，但可能有助于解决问题。下面是我用来生成epub的代码的摘录，这些代码不仅仅是具有不同扩展名的zip文件。这个压缩部分在数百次运行中从未失败。
Public Function Zip_Create(ByVal StrFilePath As String) As Boolean
Dim FSO As New FileSystemObject
Dim LngCounter As Long
If Not FSO.FileExists(StrFilePath) Then
'This makes the zip file, note the FilePath also caused issues
'it should be a local file, suggest root of a drive and then use FSO
'to open it
LngCounter = FreeFile
Open StrFilePath For Output As #LngCounter
Print #LngCounter, "PK" & Chr(5) & Chr(6) & String(18, vbNullChar)
Close #LngCounter
End If
Zip_Create = True
End Function
Public Function Zip_Insert(ByVal StrZipFilePath As String, ByVal StrObject As String) As Boolean
Dim BlnYesNo As Boolean
Dim LngCounter As Long
Dim LngCounter2 As Long
Dim ObjApp As Object

Dim ObjFldrItms As Object
Dim StrContainer As String
Dim StrContainer2 As String
If Procs.Global_IsAPC Then
'Create the zip if needed
If Not FSA.File_Exists(StrZipFilePath) Then
If Not Zip_Create(StrZipFilePath) Then
Exit Function
End If
End If
'Connect to the OS Shell
Set ObjApp = CreateObject("Shell.Application")
'Pause, if it has just been created the next piece of
'code may not see it yet
LngCounter2 = Round(Timer) + 1
Do Until CLng(Timer) > LngCounter2
DoEvents
Loop
'Divide the path and file
StrContainer = Right(StrObject, Len(StrObject) - InStrRev(StrObject, "\"))
StrObject = Left(StrObject, Len(StrObject) - Len(StrContainer))
'Connect to the file (via the path)
Set ObjFldrItm = ObjApp.NameSpace(CVar(StrObject)).Items.Item(CVar(StrContainer))
'Pauses needed to avoid all crashes
LngCounter2 = CLng(Timer) + 1
Do Until CLng(Timer) > LngCounter2
DoEvents
Loop
'If it is a folder then check there are items to copy (so as to not cause and error message
BlnYesNo = True
If ObjFldrItm.IsFolder Then
If ObjFldrItm.GetFolder.Items.Count = 0 Then BlnYesNo = False
End If
If BlnYesNo Then
'Take note of how many items are in the Zip file
'Place item into the Zip file
