Hello!
I am trying to write a script to automatically generate renditions for .tif, .jpg and .psd files.
(I'm on ImageMagick 7.0.2-1 Q16 x64 2016-06-23)

Right now, my script says:

@echo off

set ORIGINAL_FOLDER=.\original-assets
set RENDITION_FOLDER=.\renditions

for /f %%A in ('dir /B %ORIGINAL_FOLDER%') DO (
echo Generating Renditions for %%A...
::* Generate High Res JPEG (300dpi) CMYK
convert %ORIGINAL_FOLDER%/%%A -define jpeg -density 300 -colorspace CMYK -gravity center -adjoin %RENDITION_FOLDER%/300CMYK/%%A_300CMYK.jpg

::* Generate High Res JPEG (300dpi) RGB
convert %ORIGINAL_FOLDER%/%%A -define jpeg -density 300 -colorspace sRGB -gravity center %RENDITION_FOLDER%/300RGB/%%A_300RGB.jpg

::* Generate Low res jpeg (150 dpi) RGB
convert %ORIGINAL_FOLDER%/%%A -density 150 -define jpeg -colorspace sRGB -gravity center %RENDITION_FOLDER%/150/%%A_150.jpg

::* Generate Low res jpeg (72 dpi) RGB
convert %ORIGINAL_FOLDER%/%%A -define jpeg -density 72 -colorspace sRGB -gravity center %RENDITION_FOLDER%/72/%%A_72.jpg

The script runs successfully on the .tif file, but I get the following error for the .jpg and .psd:

Why did it work for the .tif but not the others? What do I need to add to my script to get it to work? What does the error mean?
I am completely new to IM and have zero coding experience.

Any help is much appreciated!!

Do a directory listing. Do you actually have a file called ".\original-assets/Collect"? I suspect you don't, but do have a file with a space in the name, something like ".\original-assets/Collect something else.jpg". If so, then you should put quotes around filenames in your convert.

It was the filename which had spaces. It works now! Thank you!
