Delete Files After Filename - vbscript - vbscript

Basically I am trying to write a script to delete files after a certain filename, so based on the below file list
FILE_000001_FULL.ZIP
FILE_000002_FULL.ZIP
FILE_000003_FULL.ZIP
FILE_000004_FULL.ZIP
FILE_000005_FULL.ZIP
FILE_000006_DELTA.ZIP
FILE_000007_DELTA.ZIP
FILE_000008_FULL.ZIP
Everything up until FILE_000005_FULL.ZIP would be deleted. The files are created using a tool and will be sorted by file name, so highest number first. Basically need the 2 latest FULL files kept and the DELTA's (if any) between them. I hope that makes sense.
So far, this is what I have, but just loops constantly, not just until it finds the 2 latest fulls.
Dim fso, folder, files, ToDel, sfolder
Set fso = CreateObject("Scripting.FileSystemObject")
sFolder = ("C:\MDS")
Set ToDel = fso.CreateTextFile ("C:\MDS\FileList.txt", True)
Set folder = fso.GetFolder(sFolder)
set files = folder.files
For each folderIDX In files
ToDel.WriteLine(folderidx.Name)
Next
ToDel.close
Dim arrFileLines()
i = 0
Set ObjFile = FSO.OpenTextFile("C:\MDS\FileList.txt", 1)
Do Until objFile.AtEndOfStream
Redim Preserve arrFileLines(i)
arrFileLines(i) = objFile.ReadLine
i = i + 1
Loop
ObjFile.Close
s = 0
Do While s < 2
For l = Ubound(arrFileLines) to LBound(arrFileLines) Step -1
For Each strLine in arrFileLines
IF InStr(strLine, "FULL") <> 0 Then
wscript.echo "Found Full!!!!"
wscript.echo strLine, s
s = S + 1
End If
Next
Next
LooP
My thoughts was to delete the lines from the text file, then use this text file to delete the files from the directory.
Hopefully that all makes sense and someone can pass some advice on!

You should be able to do this with two iterations through your folder and without the need/use of a text file. During the first pass, record the numbers assigned to the two latest FULL's. Then, in your second pass, delete any files that are less than your second-highest FULL.
Here's how it might look:
' First pass: Find the two latest FULLs...
For Each File In FSO.GetFolder("c:\mds").Files
' Is this a FULL?
If Right(File.Name, 8) = "FULL.ZIP" Then
' Get the numeric value from the file name (6 digits starting as pos 6)...
intNum = CLng(Mid(File.Name, 6, 6))
' Maintain the two latest FULLs...
If intNum > intMax1 Then
intMax2 = intMax1
intMax1 = intNum
ElseIf intNum > intMax2 Then
intMax2 = intNum
End If
End If
Next
' Second pass: Delete anything prior to the second-latest FULL...
For Each File In FSO.GetFolder("c:\mds").Files
intNum = CLng(Mid(File.Name, 6, 6))
If intNum < intMax2 Then File.Delete
Next

Delete lines starting from bottom

I got this code which deletes 10 lines starting from the top.
Is it possible to do the same but starting the delete from the bottom to the top of the txt file?
So if I have 30 lines, I want the last 10 or 20 lines to be deleted.
Const FOR_READING = 1
Const FOR_WRITING = 2
strFileName = "C:\scripts\delete.txt"
iNumberOfLinesToDelete = 10
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objTS = objFS.OpenTextFile(strFileName, FOR_READING)
strContents = objTS.ReadAll
objTS.Close
arrLines = Split(strContents, vbNewLine)
Set objTS = objFS.OpenTextFile(strFileName, FOR_WRITING)
For i=0 To UBound(arrLines)
If i > (iNumberOfLinesToDelete - 1) Then
objTS.WriteLine arrLines(i)
End If
Next
If you read the entire file into an array of lines you'd use more or less the same approach for removing lines from beginning or end.
To remove lines from the beginning you start at an offset after the lines that you want removed:
filename = "C:\path\to\your.txt"
numLinesToRemove = 10
Set fso = CreateObject("Scripting.FileSystemObject")
txt = Split(fso.OpenTextFile(filename).ReadAll, vbNewLine)
Set f = fso.OpenTextFile(filename, 2)
For i = numLinesToRemove To UBound(txt)
f.WriteLine txt(i)
Next
f.Close
To remove lines from the end of the file you stop before the lines that you want removed:
filename = "C:\path\to\your.txt"
numLinesToRemove = 10
Set fso = CreateObject("Scripting.FileSystemObject")
txt = Split(fso.OpenTextFile(filename).ReadAll, vbNewLine)
Set f = fso.OpenTextFile(filename, 2)
For i = 0 To UBound(txt) - numLinesToRemove
f.WriteLine txt(i)
Next
f.Close
This approach only works for small files, though. If you need to process large files you usually can't read the entire file into memory. If you did your computer would start swapping data from memory to disk, causing the system to slow down to a crawl. To avoid this you normally read the file line by line in a loop and write to a temporary file, then replace the original file with the temp file after processing is complete.
Removing lines from the beginning of a file is still fairly trivial, because TextStream objects have a Line property that holds the current line number (i.e. the number of the line that the next ReadLine call would read).
Set f = fso.OpenTextFile(filename)
Set tmp = fso.OpenTextFile(filename & ".tmp", 2, True)
Do Until f.AtEndOfStream
If f.Line <= numLinesToRemove Then
f.SkipLine
Else
tmp.WriteLine f.ReadLine
End If
Loop
f.Close
tmp.Close
However, you can't do that for removing lines from the end of the file, because you don't know the number of lines beforhand. One way to deal with this is to create a ring buffer the size of the number of lines you want to remove, fill it as you read lines from the input file, and write lines to the output file when they are removed from the buffer. That way the last numLinesToRemove lines are still in the buffer (not written to the output file) when the loop terminates.
ReDim buf(numLinesToRemove) 'ring buffer
i = -1 'ring buffer pointer
Set f = fso.OpenTextFile(filename)
Set tmp = fso.OpenTextFile(filename & ".tmp", 2, True)
Do Until f.AtEndOfStream
i = (i + 1) Mod numLinesToRemove 'advance ring buffer pointer
'if current buffer slot is filled write it to the output file ...
If Not IsEmpty(buf(i)) Then tmp.WriteLine buf(i)
'... then put current line from input file into current buffer slot
buf(i) = f.ReadLine
Next
f.Close
tmp.Close
In both cases you'd replace the original file after processing is complete, e.g. like this:
fso.DeleteFile filename
fso.MoveFile filename & ".tmp", filename
just loop backwards in your for statement
For i=UBound(arrLines) To (UBound(arrLines) -10) step -1
Next

VBscript - select file based on priority

I have a folder that I will be looping through to process files differently based on their filenames. Doing good on my script (first one!), until I realized there will be filenames that have also have numbers representing priority. For example in the folder there may be:
'NV_CX67_mainx.dxf'
'NV_CX67_mainx1.dxf'
'NV_CX67_mainx2.dxf '
'NV_CX67_mainxroad.dxf'
'NV_CX67_motx.dxf'
'NV_CX67_resxroad.dxf'
The mainx, mainx1 and mainx2 are the same file type but mainx2 has priority and should be the only one processed. Currently, my statement is:
If Instr(1,FileRef, "mainx",1) then
How might I add a 2nd filter to process only the file with the highest number before moving onto the next file?
You are going to have run through the following process
Sort your input files
Loop through each file one by one
Compare the current file to the previous one you looked at minus the numbers to see if it greater.
Only process an item you have scanned all the similar items to ensure this one has the largest number
I wrote up an example below. Notice only NV_CX67_mainx4.dxf, and NV_CX67_mainxroad.dxf get processed:
Option Explicit
Dim i, sBaseFileName, sPrevFileName, prevBaseFile
sPrevFileName = "~"
prevBaseFile = "~"
Dim arr(5)
'Initialize test array. This will need to be sorted for this code to work properly
arr(0) = "NV_CX67_mainx.dxf"
arr(1) = "NV_CX67_mainx4.dxf"
arr(2) = "NV_CX67_mainx2.dxf"
arr(3) = "NV_CX67_mainxroad.dxf"
arr(4) = "NV_CX67_motx.dxf"
arr(5) = "NV_CX67_resxroad.dxf"
'Loop through the array
For i = LBound(arr) to UBound(arr)
If Instr(1, arr(i), "mainx",1) Then 'Check prev qualifier
sBaseFileName = getsBaseFileName(arr(i))
'First Case
If prevBaseFile = "~" Then
prevBaseFile = sBaseFileName
sPrevFileName = arr(i)
'Tie - Figure out which one to keep based on number at end of file name
ElseIf prevBaseFile = sBaseFileName Then
sPrevFileName = GetMaxFile(sPrevFileName, arr(i))
prevBaseFile = getsBaseFileName(sPrevFileName)
'New Case - Process prev case
Else
'Process File
MsgBox ("Processing " + sPrevFileName)
'Capture new current file for future processing
sPrevFileName = arr(i)
prevBaseFile = getsBaseFileName(sPrevFileName)
End If
End If
Next
'If last file was valid process it
If sPrevFileName <> "~" Then
MsgBox ("Processing " + sPrevFileName)
End If
'Return the larger of the two files based on numbers at end.
'Note "file9.txt" > "file10.txt" in this code
Function GetMaxFile(sFile1, sFile2)
GetMaxFile = sFile1
If sFile2 > sFile1 Then
GetMaxFile = sFile2
End If
End Function
'Return the file without extension and trailing numbers
'getsBaseFileName("hello123.txt") returns "hello"
Function getsBaseFileName(sFile)
Dim sFileRev
Dim iPos
getsBaseFileName = sFile
sFileRev = StrReverse(sFile)
'Get rid of the extension
iPos = Instr(1, sFileRev, ".",1)
If iPos < 1 Then
Exit Function
End If
sFileRev = Right(sFileRev, Len(sFileRev)-iPos)
'Get rid of trailing numbers
Do
If InStr(1, "1234567890", Left(sFileRev, 1), 1) Then
sFileRev = Right(sFileRev, Len(sFileRev)-1)
Else
Exit Do
End If
Loop While(Len(sFileRev) > 0)
getsBaseFileName = StrReverse(sFileRev)
End Function

Vbs - File Cont \ File Delete

I am creating a guy script read files in a folder, (Scripting.FileSystemObject), but I would like to relate a indice inpubox type int to determine which file in the folder I'll write on the screen.
Ex: indice = inputbox "" ← 4 grab the indice file in the folder 4 and esquever your name on the screen.
  I wonder if this is possible because already tried in many ways and even by matrix, but without result.
This and my code. I do not know but where to go!
Dim sFO, NovaPasta, Folder,File, Indice
Dim inpast(4)
'Setup
Set sFO = CreateObject("Scripting.FileSystemObject")
Set Folder = sFo.GetFolder("C:\Users\502526523\Documents\Control")
NovaPasta = "Control"
'Development
If Not sFO.FolderExists (NovaPasta) = True Then
sFO.CreateFolder (NovaPasta)
Wscript.Sleep 900
WScript.Echo "Pasta Criada"
Else
WScript.Echo "Pasta Existente "
End If
' Line Verificas a quantidade de inpastas dentro da pasta, se > 5
' deleta os exedentes com data mais antiga
For Each file In folder.Files
If Folder.Files.Count > 5 And (DateDiff("d", file.DateLastModified, Now) > 7) Then
WScript.Echo (file.Name & vbLf)
WScript.Echo ("Total files :" & Folder.Files.Count)
File.Delete
End If
Next
For Each file In folder.Files
inpast(0) = (file.Name)
inpast(1) = (file.Name)
inpast(2) = (file.Name)
inpast(3) = (file.Name)
inpast(4) = (file.Name)
Indice = Inputbox ("Digite o valor do Indice de 0...30")
Select Case Indice
Case 0
WScript.Echo inpast(0)
Case 1
WScript.Echo inpast(1)
Case 2
WScript.Echo inpast(2)
Case 3
WScript.Echo inpast(3)
Case 4
WScript.Echo inpast(4)
End Select
Next
Still not sure if I understand your question correctly. You mean you have a list of filenames and you want to display the filename corresponding to the number the user entered via an InputBox? If that's what you want you should change your second For Each loop like this:
i = 0
For Each file In folder.Files
inpast(i) = file.Name
i = i + 1
Next
Indice = InputBox("Digite o valor do Indice de 0...30")
WScript.Echo inpast(CInt(Indice))
Note, however, that the condition in your first For Each loop does not guarantee you'll only ever have 5 files left after the loop. If for some reason the folder contains more than 5 files that were modified within the past 7 days the second loop would fail with a "subscript out of range" error.
There are several ways you could handle this:
Dynamically resize the inpast array so it can hold more than 5 items.
Sort the files in the folder by last modification date (e.g. like this) and delete everything except the 5 most recent files.
Cut off the second For Each loop after the 5th iteration (Exit For).
Note also, that you should sanitize your input. (What happens when users enter text, an invalid number, or press "Cancel"?)
Set fso = CreateObject("Scripting.FileSystemObject")
Dirname = InputBox("Enter Dir name")
'Searchterm = Inputbox("Enter search term")
ProcessFolder DirName
Sub ProcessFolder(FolderPath)
' On Error Resume Next
Set fldr = fso.GetFolder(FolderPath)
msgbox fls.count
Msgbox fls.item("computerlist.txt")
End Sub
To do the 7th
Set Fls = fldr.files
For Each thing in Fls
Count = Count + 1
If count = 7 then msgbox Thing.Name & " " & Thing.DateLastModified
Next

Error: Input past end of the file?

I am working on VB Script and I am trying to read the txt file and sore it in a array.
I check for the number of lines and use that variable for the For loop.
I am getting an error Input past end of the file.
I am not sure how to solve this problem.
looking forward for your help.
Thank you!!
Dim num As Integer
'Skip lines one by one
Do While objTextFile.AtEndOfStream <> True
objTextFile.SkipLine ' or strTemp = txsInput.ReadLine
Loop
num = objTextFile.Line - 1
Dim para()
ReDim para(num)
For i = 1 To num
para(i) = objTextFile.ReadLine
Next
For two reasons (the second coming intp play if you fix the first):
You have already read the file to the end. You would need to reset or reopen it.
You are always reading 125 lines, regardless of how many lines you found.
You can read the lines and put them in the array in one go:
Dim para()
Dim num As Integer = 0
Do While Not objTextFile.AtEndOfStream
ReDim Preserve para(num)
para(num) = txsInput.ReadLine
num = num + 1
Loop
Note: Arrays are zero based, and the code above places the first line at index 0. If you place the data from index 1 and up (as in the original code) you leave the first item unused, and you have to keep skipping the first item when you use the array.
Edit:
I see that you changed 125 to num in the code, that would fix the second problem.
I've used the following style code which is fast for small files:
Const ForReading = 1
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTextFile = objFSO.OpenTextFile(strList, ForReading)
strText = objTextFile.ReadAll
objTextFile.Close
arrList = Split(strText, vbCrLf)

How to get the most recently modified file of a certain size in a folder in VBScript

Here is the problem:
I have a folder with many text files. I want to find the file I need to parse; however, it has a different name each time so I cannot use the file name. What I know about it is that it is always 39KB (although marginally different each time, so I check for >39000 and <40000). However, there are often several files of that same size in the folder, and I would like to select the MOST recently modified one.
What I have:
If fNewest = "" Then
Set fNewest = objFile
ElseIf fNewest.DateLastModified < objFile.DateLastModified Then
Set fNewest = objFile
End If
If (objFile.Size > 39000 and objFile.Size < 40000) Then
Msgbox fNewest
End If
While fNewest is returning the path to the file I want (the 39Kb file that was most recentl modified), Msgbox is being called 4 times (which is the number of occurances of a file that is 39Kb in that folder). Does anyone know how I can modify this code to correct this, or a better way to run this check?
My ultimate coal is to have a condition statement(s) as above so Msgbox is replaced with the call to the specific function that takes that file and parses it.
Thanks.
Your nesting is off. The MsgBox should be outside the loop with which you iterate over the files in your folder, and the assignment should be inside the conditional that checks the file size. Try this:
Set fso = CreateObject("Scripting.FileSystemObject")
For Each f In fso.GetFolder("...").Files
If f.Size > 39000 and f.Size < 40000 Then
If IsEmpty(newest) Then
Set newest = f
ElseIf newest.DateLastModified < f.DateLastModified Then
Set newest = f
End If
End If
Next
If Not IsNull(newest) Then MsgBox newest.Name
Dim newest, fso
Set fso = CreateObject("Scripting.FileSystemObject")
For Each f In fso.GetFolder(".").Files
If f.Size > 39000 and f.Size < 40000 Then
If IsEmpty(newest) Then
Set newest = f
ElseIf newest.DateLastModified < f.DateLastModified Then
Set newest = f
End If
End If
Next
If Not IsEmpty(newest) Then MsgBox newest.Name
(I just replace IsNull with IsEmpty)
