And you don’t know why?

Pocket digital cameras can quickly create monster video files. The original video of the Canadian Freight Train is 221Mb – from a pocket digital camera!

You could always browse your way through Windows Explorer and just figure it out – or you could download a fabulous free tool called SequoiaView and let that help you figure it out.

Here’s a pretty picture of my disk usage. I’m about to replace my hard drive anyway – that will be a future blog post – so it’s time to clear out the junk. But where is the junk?


It’s somewhere in this lot!

Sequoia is very easy to run. Not so easy to fully understand – and certainly not to be used as a tool to blindly go deleting files – just because they’re big!

The display above is a screen grab for my PC, and if I hover my mouse and screen grab again on that train video.


The bottom of the screen shows us details of the file size etc., whilst the ‘fly out’ gives us the file name and location.

WARNING – use SequoiaView to help you see the size and location of your files. back up any important files. If you don’t know what a file does – do NOT delete it!

Was this information helpful? I have a lot of technical utilities which may be helpful – what would help you?

In response to the first query below I’ve added to this blog post with details of a great free tool from Codeplex.

This utility will let you download a zip file – where the only file is the .exe which can be run without installation. Beware of the detailed terms and conditions which you have to agree to before downloading the package – this is priceless 🙂


The download zip is only 49kb, and the file can be run by simply double clicking it.

The top level result is a bit disappointing, as it takes a while to get to here ..


But double click the disk for the real results. (The software author uses the phrase ‘children’ to denote sub folders and subfolders)

Double click the ‘self and children’ tab to see your large files


Notice that ‘Documents and Settings’ has a zero size – this is because all the files are in folders. Just keep double clicking  a folder name to see what’s going on. To go back up a level, double click in the space beside the arrow.


A brilliant little tool – now to clear out some of those pictures of feet, fields and sky 🙁
