With a file system, the data is contained in its files and directories, and the metadata tracks information about each of these objects: Is it a regular file, a directory, or a link?What is its size, creation date, last modified date, file owner, group owner, and access permissions?

Although the majority of the code is repetitive amongst routines, it is presented this way to isolate each routine for simplicity.I'm trying to find out how to read/write to the extended file properties in C# e.g. Name Space("C:\tmp") For i = 0 To 34 arr Headers(i) = obj Folder. Items, i) Next For Each str File Name In objfolder. Write Line(i & vb Tab & arr Headers(i) & ": " & objfolder. If it returns null or whitespace space then you have all the headers.using Microsoft. Comment, Bit Rate, Date Accessed, Category etc that you can see in Windows explorer. EDIT: I'll mainly be reading/writing to video files (AVI/DIVX/...) Sub Main() Dim arr Headers(35) Dim shell As New Shell32. Get Details Of(str File Name, i)) Next Next End Sub Worth noting that on Windows 7 (at least) you can increase the size of arr Headers to just over 280 and get back plenty of additional meta-data. For this reason, the methods, it should be mentioned that different file systems have different notions about which attributes should be tracked.For this reason, related file attributes are grouped together into views.
