IT Adventures: Episode One - Mind Blank Holidays.

Is there anyway I can erase them and use them as regular USB drives? I don't have the password to unlock them. I grabbed a couple and as far as I know they are still good. The key method is this one which recursively inspects sub-directories to come up with a total size.My company is throwing away some Ironkey USB drives. NET core command line app here calculates directory sizes for a given path: RichTextBox1.AppendText(' files:' + fileCount.ToString()) RichTextBox1.AppendText(' ' + e.Message) RichTextBox1.Text = prevText + (' Counting size: ' + dataSize.ToString()) Get the subdirectories for the specified directory.ĭirectoryInfo dir = new DirectoryInfo(sourceDirName) įoreach (FileInfo file in dir.EnumerateFiles('*', SearchOption.AllDirectories)) private void Director圜ountEnumTest(string sourceDirName) There is still a problem with UnauthorizedAccess. While enumerating files even though the filename is long the FileInfo returned by the EnumerateFiles don't cause problems as long as the starting directory name is not too long. Long path names don't cause any problems since FileInfo or DirectoryInfo are not tried to be created for the long path name. This method also allows updating the UI while going through the files and counting the size. The fastest way that I came up is using EnumerateFiles with SearchOption.AllDirectories.

To String files = Directory.GetFiles(args, '*', SearchOption.AllDirectories) This example only calculate the files in current folder, so if you want to calculate all the files recursively, you can change the String files = Directory.GetFiles(args) The example displaysoutput like the following: Protected static float CalculateFolderSize(string folder)įoreach (string file in Directory.GetFiles(folder))įoreach (string dir in Directory.GetDirectories(folder))Ĭonsole.WriteLine('Unable to calculate folder size: bytes', files.Length, totalSize) I've written the following routine to manually traverse through a directory and calculate its size in C#/.NET:
