I have colleagues who have 20 copies of the same document with slight variations named like this in a folder. I honestly don't understand how they function at work.
I work in Finance at my company and we always save revised copies for Excel files instead of saving over.
But we also have strict rules on it. File name is always "xxxx_Workbook Template Name_MMDDYY.xlsx" or "_YYYY_MM.xlsx", depending on how often it gets updated.
Older versions get moved to a subfolder. It helps us go back and find out what something was if there was a mistake or revert back if Excel done fucks up.
It never works when you need it. Like "that file was too big", that file was on a network share, that file is outside the window of how many old changes are saved. It's like using an undelete utility. Sometimes you get lucky.
It's better to save every change as a dated/numbered file or use a real source control system.
Every tech noob user I see. Worse if it's mac because 1) I cannot use it for the life of me and 2) almost every Mac user stores it in the same default downloads folder and won't know what path it's in unless they use the Finder tool.
Nah, because when I ask them for info they stare at their directory and have to randomly open files for 20 minutes until they land on the item of interest...
