Finding total folder size

Is there an easy way to learn what is the total size of a directory and
all of its subdirectories?

Used it for years

I'm running low on disk space and need to find the junk, among the many

You don't say what operating system you're on.

Windows: open a command window (Start>Run>cmd), then at the prompt:

c:\whatever>dir /s

Mac (maybe; I don't have one to test on, but this works on most Unix-
like systems): open a terminal window

[me@mycomputer ~]$ du

In either case, if you want an editable copy, add " > files.txt"
(without the quotes) to the end of the command.

sub-folders.

In Windows Explorer*(1, 2), right click on the folder and select properties.

There is a freeware program available that will add a "Folder Size" column
to Windows Explorer, but it only works on the c: drive.
There may be Windows Explorer replacements that provide this information as
well

*2 as opposed to Explorer or Internet Explorer

Then you may be interested in big files rather than just big folders.

I use the Windows Search command looking for files based on size. I usually
start by looking for > 100M files -- as they are the real space eaters, and
then reduce the limit until I've found enough I can delete to get the disk
usage down far enough.

I find it tends to be music (.WAV) files and various backup copies of my
main FTM database that are chewing up my space.

Start the prompt command and type:

the drive letter of the disk, i.e.

c:

cd \
dir /s >dir.c

then, edit the dir.c file and search all the lines with the size of
the directory.

For Windows, download MouseSoft Directory Size (freebie). It will
list the sizes of all the directories on the drive and sorts them from
largest to smallest.
You can click on a directory to see the sizes of its sub-directories.

buy a usb drive and back up your hard disk on to that first
or at least "my documents" for each user
