VBA列出没有FileSystemObject的子文件夹中的所有文件（快速方式） [英] VBA List all files (fast way) in subfolders without FileSystemObject

问题描述

我正在寻找一种快速列出文件夹子文件夹中的所有文件的方法。基于FileSystemObject的方法太慢 - 从网络驱动器（intranet）列出416个文件名需要大约6分钟，因为我明白Dir（）函数不允许循环遍历子文件夹。

I'm searching for a way for fast listing all files from subfolders of folder. Approach based on FileSystemObject is too slow - it takes ~6 minutes for listing 416 filenames from a network drive (intranet), as I understand Dir() function doesn't allow for looping throught subfolders.

推荐答案

使用CMD：

Sub SO()

Const parentFolder As String = "C:\Users\bloggsj\folder\" '// change as required, keep trailing slash

Dim results As String

results = CreateObject("WScript.Shell").Exec("CMD /C DIR """ & parentFolder & "*.*"" /S /B /A:-D").StdOut.ReadAll

Debug.Print results

'// uncomment to dump results into column A of spreadsheet instead:
'// Range("A1").Resize(UBound(Split(results, vbCrLf)), 1).Value = WorksheetFunction.Transpose(Split(results, vbCrLf))
'//-----------------------------------------------------------------
'// uncomment to filter certain files from results.
'// Const filterType As String = "*.exe"
'// Dim filterResults As String
'// 
'// filterResults = Join(Filter(Split(results, vbCrLf), filterType), vbCrLf)
'//
'// Debug.Print filterResults
End Sub
