Please add less command to your shortcut list as it is more efficient than more as can be seen in this link

Hi, can anyone help me? I'm new to this

I want to make a batch file that chooses each green labeled files within a certain folder and unzips the “Links.zip” and then creates folders (named: Edited, Buildings, Extra, Front Cover, Interior, Map, Properties (Properties has three sub Folder inside: CGI, Floor Plans and Properties 290x200px) and Town) it the organises each file within the folder into those categories based upon its name

It also creates another Folder within each green labeled file called “Optimised” with the same subfolders (named: Edited, Buildings, Extra, Front Cover, Interior, Map, Properties (Properties has three sub Folder inside: CGI, Floor Plans and Properties 290x200px)

Then uses photoshop to optimise the files within the “Links” folder, in each green tagged folder, to certain parameters e.g Quality 3, 1400px width and 1400px height and places them into the “Optimised” file within.

Then starts another photoshop optimisation with “Links” subfolder “Properties” and it’s sub folder “CGI” and then places them into the sub-sub-folder of “Optimised” - “Properties” - “Properties 290x200px) with the settings Quality 10, 290px width and 200px height

Then takes an InDesign File within the green tagged file and exports each page as a high quality .jpg, into a file named “jpg” and then optimise those pages using photoshop with a quality 10, px 1500 width and 1500 height into a subfolder within that folder called “Optimised”

I need it to loop with every green tagged file within a folder

I have so many files to go through exactly like this, I wanted to automate it as it’s rather over whelming, I have tried Automator on Mac, but I’m so lost. Can anyone help?

I am getting this update message, only to be told file is corrupted when trying to update, then it reminds me the next day. I searched online and found a --ignore command for Terminal, but that doesn't seem to work in Big Sur? So I'm not sure how to remove this update as the application is nowhere to be found on my laptop.
