This should do it from the command-line...

 
for %f in (*.*) do if not %~zf gtr 0 del %f

Here is a scripted version...
@echo off
for /r %%f in (\path\so2\*.*) do (
	if %%~zf equ 0 (
		set /p p=%%f zero bytes... <nul
		del %%f
		echo deleted!
	)
)

@x66_x72_x65_x65:

Just wanted to point out that the scripted version you have specifies the location (\path\so2) that the asker mentioned however the one liner does not.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Right-- one liner was intended for use in current folder (current folder being ...  \path\so2 ) <--- DISCLAIMER
:)

Here is another ver with some error checking...

 
@echo off
for /r %%f in (\path\so2\*.*) do (
	if %%~zf equ 0 (
		set /p p=%%f zero bytes... <nul
		del "%%f"/f/q/a>nul 2>&1||echo remove failed!
		if not exist %%f echo removed.
	)
)

I get this error message for the command line below. I already cd'd into the current directory. I tried stating the directory after the f and got the same message

[rhuff@huina so2]$ for %f in (*.*) do if not %~zf gtr 0 del %f
Badly placed ()'s.

Tried the scripted version and got this

[rhuff@huina ~/scripts]$ sh zero.sh
zero.sh: line 1: @echo: command not found
zero.sh: line 2: syntax error near unexpected token `%%f'
zero.sh: line 2: `for /r %%f in (/path/path/path/path/so2*.*) do ('
[rhuff@huina ~/scripts]$

Also so2 is part of the path name so /path/so2/ all files would be after so2/

As you put Powershell in the zones, everyone assumed you were wanting a Windows solution.


For *nix

find /path/so2 -type f -size 0 | xargs rm
