If you have a large file and when you are extracting it there is not enough space on disk (say you are extracting a 1GB file to a USB drive with 500MB free), an exception is thrown (as expected) but in that exception you cannot delete the file currently
I tried calling dispose but that does not help. Whatever has that file open, still has the file open after calling dispose (which surprised me).
Any way around this?
Here is some sample code. Of course, with this code you should never encounter such a problem but someone else could write to the drive after you start ExtractAll and before ExtractAll completes.
Using zip As New Ionic.Utils.Zip.ZipFile(TextBox2.Text)
Dim lngTotal As Long = 0
For Each entry As Ionic.Utils.Zip.ZipEntry In zip
lngTotal += entry.UncompressedSize
Dim boolEnoughSpace As Boolean = True
Dim strDrive As String = System.IO.Path.GetPathRoot(TextBox3.Text)
If strDrive.Contains(":") Then
Dim di As New System.IO.DriveInfo(strDrive)
If di.AvailableFreeSpace > lngTotal Then
boolEnoughSpace = True
boolEnoughSpace = False
Console.WriteLine("Total: " & lngTotal.ToString("#,##0"))
If boolEnoughSpace Then
MessageBox.Show("Not enough space")
Catch ex As Exception
If ex.Message.Contains("There is not enough space on the disk.") Then
MessageBox.Show("Error: " & ex.Message)
