Deleting directory in an array - arrays

Question

I have this code that gets all file types.
Dim file as variant
file = Application.GetOpenFilename("All Files, *.*", , "Select File", , True)
Then I have to print it in the cells on a sheet.
For i = 1 To UBound(file)
lRow = Cells(Rows.count, 15).End(xlUp).Row
lRow = lRow + 1
ThisWorkbook.Sheets("Main").Range("O" & lRow).Value = CStr(file(i))
Next i
but what I want is first check the contents of the array. If the array has this file type, then I have to remove it in the arraylist. After that, a message will pop out that this files are removed.
dim arr() as string
arr = Split("ade|adp|app|asp|bas|bat|cer|chm|cmd|com|cpl|crt|csh|der|exe|fxp|gadget|hlp|hta|inf|ins|isp|its|js|jse|" _
& "ksh|lnk|mad|maf|mag|mam|maq|mar|mas|mat|mau|mav|maw|mda|mdb|mde|mdt|mdw|mdz|msc|msh|msh1|msh2|" _
& "mshxml|msh1xml|msh2xml|ade|adp|app|asp|bas|bat|cer|chm|cmd|com|cpl|crt|csh|der|exe|fxp|gadget|hlp|" _
& "hta|msi|msp|mst|ops|pcd|pif|plg|prf|prg|pst|reg|scf|scr|sct|shb|shs|ps1|ps1xml|ps2|ps2xml|psc1|psc2|tmp|url|vb|vbe|vbs|vsmacros|vsw|ws|wsc|wsf|wsh|xnk", "|")
I just don't know where I have to start. I have found a little bit same problem here in this post, but I just can't understand it. Thanks!

You can use a RegExp and a varaint array to do this quickly
This code looks for path... dot extension end string so it is more robust than your current array which may remove files based on the path name rather than file type
Sub B()
Dim fName As Variant
Dim objRegex As Object
Dim lngCnt As Long
Dim rng1 As Range
Set objRegex = CreateObject("vbscript.regexp")
On Error Resume Next
fName = Application.GetOpenFilename("All Files, *.*", , "Select file", , True)
If Err.Number <> 0 Then Exit Sub
On Error GoTo 0
With objRegex
.Pattern = ".*\.(ade|adp|app|asp|bas|bat|cer|chm|cmd|com|cpl|crt|csh|der|exe|fxp|gadget|hlp|hta|inf|ins|isp|its|js|jse|" _
& "ksh|lnk|mad|maf|mag|mam|maq|mar|mas|mat|mau|mav|maw|mda|mdb|mde|mdt|mdw|mdz|msc|msh|msh1|msh2|" _
& "mshxml|msh1xml|msh2xml|ade|adp|app|asp|bas|bat|cer|chm|cmd|com|cpl|crt|csh|der|exe|fxp|gadget|hlp|" _
& "hta|msi|msp|mst|ops|pcd|pif|plg|prf|prg|pst|reg|scf|scr|sct|shb|shs|ps1|ps1xml|ps2|ps2xml|psc1|psc2|tmp|url|vb|vbe|vbs|vsmacros|vsw|ws|wsc|wsf|wsh|xnk)$"
`replace matching file types with blank array entries
For lngCnt = 1 To UBound(fName)
fName(lngCnt) = .Replace(fName(lngCnt), vbNullString)
Next
End With
Set rng1 = Cells(Rows.Count, 15).End(xlUp).Offset(1,0)
'dump array to sheet
rng1.Resize(UBound(fName), 1) = Application.Transpose(fName)
` remove blank entries
On Error Resume Next
rng1.SpecialCells(xlCellTypeBlanks).Delete xlUp
On Error GoTo 0
End Sub

One way would be to check that the extension it's not present in the blacklist with InStr:
Const exts = _
".ade.adp.app.asp.bas.bat.cer.chm.cmd.com.cpl.crt.csh.der.exe.fxp.gadget" & _
".hlp.hta.inf.ins.isp.its.js.jse.ksh.lnk.mad.maf.mag.mam.maq.mar.mas.mat" & _
".mau.mav.maw.mda.mdb.mde.mdt.mdw.mdz.msc.msh.msh1.msh2.mshxml.msh1xml" & _
".msh2xml.ade.adp.app.asp.bas.bat.cer.chm.cmd.com.cpl.crt.csh.der.exe.fxp" & _
".gadget.hlp.hta.msi.msp.mst.ops.pcd.pif.plg.prf.prg.pst.reg.scf.scr.sct" & _
".shb.shs.ps1.ps1xml.ps2.ps2xml.psc1.psc2.tmp.url.vb.vbe.vbs.vsmacros.vsw" & _
".ws.wsc.wsf.wsh.xnk."
Dim file As Variant
file = Application.GetOpenFilename("All Files, *.*", , "Select File", , True)
Dim i As Long, data(), count As Long, ext As String
ReDim data(1 To UBound(file) + 1, 1 To 1)
' filter the list
For i = LBound(file) To UBound(file)
ext = LCase(Mid(file(i), InStrRev(file(i), ".")))
If InStr(1, exts, ext & ".") = 0 Then ' if not blacklisted
count = count + 1
data(count, 1) = file(i)
End If
Next
' copy the filtered list to the next available row in column "O"
If count Then
With ThisWorkbook.Sheets("Main").Cells(Rows.count, "O").End(xlUp)
.Offset(1).Resize(count).Value = data
End With
End If
