VBA遍历文件夹常用有三种方法,这三种方法中,filesearch不适合2007和2010版本,而且速度比较慢,递归法速度也慢。只有用DIR加循环的方法,速度飞快。下面是三种方法的代码:
1、filesearch法
Sub test3() Dim wb As Workbook Dim i As Long Dim t t = Timer With Application.FileSearch '调用fileserch对象 .NewSearch '开始新的搜索 .LookIn = ThisWorkbook.path '设置搜索的路径 .SearchSubFolders = True '搜索范围包括 LookIn 属性指定的文件夹中的所有子文件夹 .Filename = "*.xls" '设置搜索的文件类型 ' .FileType = msoFileTypeExcelWorkbooks If .Execute() > 0 Then '如果找到文件 For i = 1 To .FoundFiles.Count 'On Error Resume Next Cells(i, 1) = .FoundFiles(i) '把找到的文件放在单元格里 Next i Else MsgBox "没找到文件" End If End With MsgBox Timer - t End Sub
2、递归法
Sub Test() Dim iPath As String, i As Long Dim t t = Timer With Application.FileDialog(msoFileDialogFolderPicker) .Title = "请选择要查找的文件夹" If .Show Then iPath = .SelectedItems(1) End If End With
If iPath = "False" Or Len(iPath) = 0 Then Exit Sub
i = 1 Call GetFolderFile(iPath, i) MsgBox Timer - t MsgBox "文件名链接获取完毕。", vbOKOnly, "提示"
End Sub
Private Sub GetFolderFile(ByVal nPath As String, ByRef iCount As Long) Dim iFileSys 'Dim iFile As Files, gFile As File 'Dim iFolder As Folder, sFolder As Folders, nFolder As Folder Set iFileSys = CreateObject("Scripting.FileSystemObject") Set iFolder = iFileSys.GetFolder(nPath) Set sFolder = iFolder.SubFolders Set iFile = iFolder.Files
With ActiveSheet For Each gFile In iFile ' .Hyperlinks.Add anchor:=.Cells(iCount, 1), Address:=gFile.path, TextToDisplay:=gFile.Name iCount = iCount + 1 Next End With
'递归遍历所有子文件夹 For Each nFolder In sFolder Call GetFolderFile(nFolder.path, iCount) Next End Sub
3、dir循环法
Sub Test() '使用双字典,旨在提高速度 Dim MyName, Dic, Did, i, t, F, TT, MyFileName 'On Error Resume Next Set objShell = CreateObject("Shell.Application") Set objFolder = objShell.BrowseForFolder(0, "选择文件夹", 0, 0) If Not objFolder Is Nothing Then lj = objFolder.self.path & "\" Set objFolder = Nothing Set objShell = Nothing
t = Time Set Dic = CreateObject("Scripting.Dictionary") '创建一个字典对象 Set Did = CreateObject("Scripting.Dictionary") Dic.Add (lj), "" i = 0 Do While i < Dic.Count Ke = Dic.keys '开始遍历字典 MyName = Dir(Ke(i)
, vbDirectory) '查找目录 Do While MyName "" If MyName "." And MyName ".." Then If (GetAttr(Ke(i) & MyName) And vbDirectory) = vbDirectory Then '如果是次级目录 Dic.Add (Ke(i) & MyName & "\"), "" '就往字典中添加这个次级目录名作为一个条目 End If End If MyName = Dir '继续遍历寻找 Loop i = i + 1 Loop Did.Add ("文件清单"), "" '以查找D盘下所有EXCEL文件为例 For Each Ke In Dic.keys MyFileName = Dir(Ke & "*.xls") Do While MyFileName "" Did.Add (Ke & MyFileName), "" MyFileName = Dir Loop Next For Each Sh In ThisWorkbook.Worksheets If Sh.Name = "XLS文件清单" Then Sheets("XLS文件清单").Cells.Delete F = True Exit For Else F = False End If Next If Not F Then Sheets.Add.Name = "XLS文件清单" End If Sheets("XLS文件清单").[A1].Resize(Did.Count, 1) = WorksheetFunction.Transpose(Did.keys) TT = Time - t MsgBox Minute(TT) & "分" & Second(TT) & "秒" End Sub |
