Find file size in folders

Hi

A bit of a dilemma here!!

I have a network folder L:\ containing hundreds of folders each containing images. Some of the image sizes are too big to display in multiple format due to a recent camera setting error.
I need to optimize these images, easily done if I can find them all but manually searching would take me days.
Do any members have example code to enable me to search through the subfolders and return the path for image file sizes say greater than 300kb?

Much Appreciated
Regards

get file size like this...

Code:

---

Private Sub Command1_Click()
Dim FileLength

CommonDialog1.ShowOpen

Open CommonDialog1.FileTitle For Input As #1    ' Open file.
FileLength = LOF(1)  ' Get length of file.
Close #1  ' Close file.

Text1.Text = FileLength & "  Bytes"
End Sub

Hi

Thanks for that, not quite what I needed really but gives me a good start.

you can use DIR to loop through all files in a directory, filelen to get the size of each file
if you want to loop through the subfolders, you could call the procedure recursively

you can then make a list (array or collection) of all files above whatever size to process later, or process them within the procedure

vb Code:

folder = "C:\test\"
fname = dir(folder & "*.jpg")      ' change to suit
do while len(fname) > 0
   if filelen(folder & fname) > testsize then ' do something
   fname = dir
loop

this will only do one folder, not the subfolders

u can list all files including sub folders using this code... add a cmd button and listbox

Code:

---

'set reference to Microsoft scripting runtime.
Option Explicit

Dim fso As New FileSystemObject
Dim fld As Folder

Private Sub Command1_Click()
List1.Clear
ListFile "c:\anyfolder", List1
End Sub

Private Function ListFile(ByVal StrFld As String, LstBx As ListBox)
Dim sFld As Folder, sFil As File

Set fld = fso.GetFolder(StrFld)
For Each sFil In fld.Files
    DoEvents
    LstBx.AddItem sFil.Path & "\" & sFil.Name
Next
 
If fld.SubFolders.Count > 0 Then
    For Each sFld In fld.SubFolders
        DoEvents
        ListFile = ListFile + ListFile(sFld.Path, LstBx)
    Next
End If
 
Set fld = Nothing
Set sFil = Nothing
 
End Function

Thats fantastic...... cheers

Yet another alternative is DRO: the DirReaderObject which is much faster than using the FSO, can also be used in script like FSO.

It returns a bunch of useful info in an ADO Recordset, which can include or omit the folders as rows:

• FullName
• Name
• Extension
• Size
• SizeOnDisk
• Created
• LastAccessed
• LastModified
• Attributes
• IsFolder

It also returns some other useful values for each node:

• IsLarge
• Level

The download at the web site includes full documentation.

Sample program:

Code:

---

Option Explicit
'
'Requires references to:
'
'  DirReaderObject Library
'  Microsoft ActiveX Data Objects 2.5 Library (or later)
'  Microsoft Shell Controls and Automation
'

Private Sub Form_Load()
    Dim strCaptionCache As String
    Dim strFolder As String
    Dim rsFiles As ADODB.Recordset   
    Show
    strCaptionCache = Caption
   
    Caption = strCaptionCache & " Scanning directory..."
    Refresh
    With CreateObject("Shell.Application").NameSpace(ssfMYPICTURES).Self
        strFolder = .Path
    End With
   
    With New BVODir.DirReaderObject
        'Default limit on returned records is 1000.
        Set rsFiles = .GetFiles(strFolder, FolderNames:=False, MaxRecords:=3000)
    End With
   
    Caption = strCaptionCache & " Loading grid..."
    Refresh
    'Filter for large .JPG, .JPEG
    rsFiles.Filter = "(Size > 300000 AND Extension = 'JPG') OR " _
                  & "(Size > 300000 AND Extension = 'JPEG')"
    Set flexFiles.DataSource = rsFiles
    rsFiles.Close
   
    Caption = strCaptionCache & " Done"
End Sub

Private Sub Form_Resize()
    If WindowState <> vbMinimized Then
        flexFiles.Move 0, 0, ScaleWidth, ScaleHeight
    End If
End Sub

You can process the Recordset (Windows' own power collection) any way you like. Above we load it into a FlexGrid control.

Thanks. Plenty of information and helpful solutions.
