How to search for the largest files on my computer vista?

To find the largest files on your computer using Explorer, open Computer and click up in the search box. When you click inside of it, a little window pops up below with a list of your recent searches and then a add search filter option.

Go ahead and click on Size and then you’ll get another menu with a couple of options:

Go ahead and pick something like Large, Huge or Gigantic otherwise you will get a list of way too many files. If you just want to see larger files, I suggest choosing huge or gigantic. Then just press enter without typing in anything else.

Alternatively, drop to command prompt type cd\

dir /s/o:s to get a listing in ascending order.

for descending order dir /s/o:-s

Since there might be a lot of files you might want to pipe it into a text file, simply add > largefiles.txt

dir /s/o:-s  > c:\temp\largefiles.txt    (the c:\temp directory must exist, if not the command will fail. Once you're on the root with cd\ just create the temp directory with md c:\temp or via the GUI, alternatively, again add & md c:\temp into the dir command)

If you want to get fancy you can also just open the results with the & 

dir /s/o:-s  > c:\temp\largefiles.txt & notepad c:\temp\largefiles.txt

Please Note:

(the c:\temp directory must exist, if not the command will fail. Once you're on the root with cd\ just create the temp directory with md c:\temp or via the GUI, alternatively, again add & md c:\temp into the dir command)

md c:\temp\ & dir /s/o:-s  > c:\temp\largefiles.txt & notepad c:\temp\largefiles.txt
