gday folks, trying to delete all avi's under 20mb

if ive got a .exe with this code in the same folder as the avi's it works fine

for /f "usebackq delims=;" %%A in (`dir /b *sample*.avi`) do If %%~zA LSS 20971520 del "%%A"

however when i try and get a bit more inventive, and try the code below, all i get is windows cannot find the path

for %%A in ('dir "%directory%\*.avi"') do If %%~zA LSS 20971520 del "%%A"

any help would be more than appreciated

cheers

It's not about being inventive, it's about not knowing some command syntax/not experimenting on command line.

Try executing in a command prompt:

dir "yourpath\*.avi"

then try again with:

dir /b "yourpath\*.avi"

DIr (without /b ) will have a "type" of output (NOT compatible with using the %%A variable), Dir /b will have another "type" of output.

And, in any case, you cannot remove the /F in the FOR command!

And, additionally the ~z won't work with "different from current" path.

In your posted example, what you want is most probably a .cmd (AND NOT a .exe) like:

@ECHO OFF

SETLOCAL ENABLEEXTENSIONS

....

.....

PUSHD %directory%

FOR /F %%A in ('DIR /B "*.avi"') DO IF %%~zA LSS 20971520 ECHO DEL "%%A"

POPD

the ECHO is there just to "protect the innocents" .

A quick powershell one-liner, for anyone who might be interested:

ls C:\somepath\ | ? { $_.Length -lt 20MB } | rm
