Topic: Code: Show memory for all folders on c drive

[T.Willey]

I don't know if anyone else has had to do this, but I had to clear some hard drive space the other day, and was trying to find which directories has the most memory occupied.  Window explorer doesn't show you how much memory unless you right click, go to properties, so this would take too much time, so I thought I would try and write one.  Here is my attempt.  It works, and is color coded by how much each folder takes.

Hope others might find it useful also, and as always, any comments/tips welcomed.

Nice one Tim - that's a usefull idea put into practice.

Cheers,
Glenn.

Thanks Glenn.

That is a nice piece of code. What would it take to add functionality to open the directory right from your window? I like the color coding idea.

I use Sequoia View to figure out what's taking up all the room on my HD

Thanks.

I don't know.  I guess I could play around somemore with it, and see what I could come up with.  Are you wanting just a list of all the files?  Or are you thinking along the lines of doing something to the files?

Thanks for the link.  I did a search before I wrote this, and didn't find anything.  I will look at it when I have a minute.

Tim, I was thinking of a list of files, that way you could delete the offending files. The software I link to opens the folder of the file you're interested so you can delete or backup/remove if you like.

That sequoia view is an example of an interface that's different, but very functional.

I think this wouldn't be too hard, but that might be a false statement.  The list is easy enough to do (I think, as I have an idea how to do it), but being able to do stuff, that might take a little reading, but should be fun.  Will see what my work load today lets me play with.

[T.Willey]

So it turned out a little harder that I thought it would be, but here is one that will list the files in the directory selected.  I will improve it as I can.  Right now you can't delete anything just see them.  I also added an 'expand all' and 'collapse all' button.  Have fun.
