<p>I'm trying to find out how to read/write to the extended file properties in C#
e.g. Comment, Bit Rate, Date Accessed, Category etc that you can see in Windows explorer. 
Any ideas how to do this?
EDIT: I'll mainly be reading/writing to video files (AVI/DIVX/...)</p>

There's
a CodeProject article
for an ID3 reader.  And a
thread at kixtart.org
that has more information for other properties. Basically, you need to call the
```
GetDetailsOf()
```
method
on the
folder
shell object for
```
shell32.dll
```
.
