With you on this, one of my pet hates. My dept issues a lor if reports which then few stored as pdfs, so calling them finalreport.pdf really isn't very helpful.......This probably sounds very petty, but hopefully doesn't make me a bell cheese.
I've never felt this to quite such an extent before, and perhaps it's a sign that I'm really passing from pleb to management, but I'm really starting to get pissed off with people who do a shit job, and i have to spend more time sorting it out than I would have done if I'd just done the job myself.
For example, we have to download a lot of information from local councils' websites. One of my colleagues has downloaded a couple of dozen pdfs and they've all got names like 876itiggt7tt96tr.pdf instead of Worthing Local Plan 2011.pdf. So I have to open each one to find out what it is the close it again to rename it then open up the ones I want again.
