Hey dude-

Here's the right way to do it, without the external downloads.  It looks like a lot at first, but once you've done it, it's very easy.  It works in all Windows versions from 7 back to 95.  For our example assume that you're comparing two directories named 'A' and 'B'.

1. run cmd.exe to get a command prompt.  (In Windows 7, the powershell won't work for this, FYI.)  Then do it again, so that you have two of them open next to each other.

2. in each window go to the directories that you want to compare.  (Using 'cd' commands.  If you're not comfortable with this, then you should probably go with the external utilities, unless you want to learn command prompt stuff.)

3. type 'dir /b > A.txt' into one window and 'dir /b > B.txt' into the other.  You'll now have two text files that list the contents of each directory.  The /b flag means bare, which strips the directory listing down to file names only.

4. move B.txt into the same folder as A.txt.

5. type 'fc A.txt B.txt'.  The command 'fc' means file compare.  This will spit out a list of the differences between the two files, with an extra line of text above and below each difference, so you know where they are.  For more options on how the output is formatted, type 'fc /?' at the prompt.  You can also pipe the differences into another file by using something like 'fc A.txt B.txt > differences.txt'.

Have fun.

Gujju dude,

Welcome to Microsoft Answers.

If you hover the pointer over the folder, it will display folder size and file information. If you do not have this activated, go to windows explorer > organize drop down > folder and search options > view > Select the Display file size information in folder tips check box, and then click OK.

I hope this helps.
