The real reason I logged in today was because I installed couple of Sims, each in their own folder so I knew I'd get duplicates and planned to sort them out but before that did this important little step:
Searched the whole folder for *.package to get all the package files listed. After that I set the order to "size" starting from the biggest one and it revealed me this;
Now you're probably wondering, what's so bad about these randomly named files I've highlighted. Well, maybe you've heard of the file that can make your game crash at for example sim aging to elder? Or perhaps your game randomly crashes when random sim enters your lot? Sometimes the file is called "uhkjhihjkj(11)" and it's a file that likes tagging along with packaged Sims and occasionally people pack it together with recolors that are actually using in-game meshes thinking that it's an oddly named mesh.
Well it's not a mesh. This file has few characteristics that make it pretty easy to spot: firstly usually the random name (or the uhkjhihjkj(11) mentioned earlier), secondly the file size, I've seen few slightly different sized ones but usually it is 6807KB or 6.64MB depending on where you check the size. Thirdly, if you open it in SimPE the contents will look like this:
It contains 1534 CRES resources, and as you can see it's CRES:es of all(?) base game accessories, clothes, hairs and who knows what else. The list is so long I never bothered checking it all though. Point however is that for whatever reason this file corrupts very easily and causes game to crash at random moments. And even if it doesn't corrupt it's just plain junk file that's taking space on your hard drive.
Now you're probably (hopefully!) looking through your Downloads folder to see if you have this file/these files and that's a good idea. Also good news is that you don't need to panic, if you find this kind of file in your game just delete it. Nothing will break, nothing needs it so your recolors will remain working. It's literally a junk file and it's perfectly save to delete so please do so.
I felt like making this little PSA since I realized that not everybody probably is aware of this stupid file lurking out there in random downloads. + this way I can just link this post whenever it sounds like somebody might have this particular issue with their game so I won't need to type it all over again every time.
