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

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

Open in new window

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!
	)
)

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.

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.
The script is for windows... sorry. :(

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
