An open source drive space viewer

[Simon Harvey]

Hi all,

I am looking to make an open source Drive space viewer. One that displays
the sizes in a graph and lets you move through the directories via a
treeview at the left.

I have three questions i hope someone could help with:

1. The problem I have is tallying up the directories and sub
directories. This is made even more complicated by the fact that I need to
allow the user to exclude certain sub directories when doing the
calculations. Does anyone know if there is a class in the framework that, at
the very least, can tell me the size of a folder and its contents.

2. Does anyone have any code or suggestions about how I could handle the
problem of excluding various directories. The user needs to click a tick box
in the treeview to have that dir included

3. Does anyone know of an open source application that I could look at for
this purpose

Thank you everyone

Simon

Simon,

1) .NET Framework has two classes that you can use to obtain the
information specific to files and directories. They are: FileInfo and
DirectoryInfo. Unfortunately, there is not a method on the
DirectoryInfo class to return the size of the Directory. I wrote a
little helper class that has a method on it that will return the size
of the directory in bytes. Here it is:

public class FileSystemHelpe r
{
private FileSystemHelpe r()
{
}
// returns the size of the given directory in bytes.
public static long GetDirectorySiz e(DirectoryInfo di)
{
if(di==null)
{
throw new ArgumentNullExc eption("di");
}
long size = 0;
FileInfo[] files = di.GetFiles();
// sum up file size
if(files!=null && files.Length>0)
{
foreach(FileInf o fi in files)
{
size+=fi.Length ;
}
}
// sum up dir size
DirectoryInfo[] dirs = di.GetDirectori es();
if(dirs!=null && dirs.Length>0)
{
foreach(Directo ryInfo dii in dirs)
{
// recursive call
size+=FileSyste mHelper.GetDire ctorySize(dii);
}
}
return size;
}

}

You can get to the contents of the directory by calling GetFiles() and
GetDirectories( ).

2) GetFiles() and GetDirectories( ) is overloaded to accept a
searchPattern so you can use that to exclude certain
files/directories.

3) I don't know of any open source tools that do this kind of stuff.

JDiskReport. Google for it.
