9. Compare two text files
'ARG(s):
FilePath1 - location of the first file to be compared
' FilePath2 - location of the second file to be compared
' FilePathDiff - location of the diffrences file
' ignoreWhiteSpace - controls whether or not to ignore differences in whitespace characters

' false - do not ignore difference in whitespace
' Return Value: true if files are identical, false otherwise'
' returned values
' -1 - requested field index that doesn't exists in the recordset

10. Example of using above functions
FilePath1 = "D:\temp\FSO\txt1.txt"
FilePath2 = "D:\temp\FSO\txt2.txt"
FilePathDiff = "D:\temp\FSO\txt_diff.txt"
d = FileCompare(FilePath1,FilePath2,FilePathDiff,false)
FilePath = "D:\temp\FSO\txt.txt"
set fold = FolderCreate ( "D:\temp\FSO\new")
set f = OpenFile(FilePath,8)
' = WriteToFile(f,"test line")
d = CloseFile(f)
set f = CreateFile(FilePath)
Fexist= CheckFileExists(FilePath)
d = WriteToFile(f,"first line")
d = WriteToFile(f,"second line")
d = CloseFile(f)
FileCopy "D:\temp\FSO\txt.txt","D:\temp\FSO\txt1.txt"
FileDelete "D:\temp\FSO\txt1.txt"
11. Create Folder if Not Exists.
Public Function ReportFolderStatus(fldr)
Dim fso, msg
Set fso = CreateObject("Scripting.FileSystemObject")
If Not (fso.FolderExists(fldr)) Then

End If
End Function
12. Count Number of Lines in txt file
Public Function NumberOfLines(FileName)
i = 0
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTextFile = objFSO.OpenTextFile(FileName, ForReading)
Do Until objTextFile.AtEndOfStream
Redim Preserve arrFileLines(i)
arrFileLines(i) = objTextFile.ReadLine
i = i +1
Loop
NumberOfLines = UBound(arrFileLines)
objTextFile.Close
End Function
13. Count Number of files in any Folder
iFileCount = 0
Set objFileSysOb = CreateObject("Scripting.FileSystemObject")
Set colFolderName = objFileSysOb.GetFolder("C:\Automation") ' Folder Path
Set vFiles =colFolderName.Files
For each vFileItem in vFiles
print vFileItem
iFileCount = iFileCount + 1
Next
print iFileCount
