My game just kept crashing and crashing and doing the 50/50 method turned out to be that the uhkjhihjkj (11) file was causing the game to crash.
It kept me wondering what this file was and how it had showed up in my Downloads folder, so I googled it.
I could not find much, only people telling other people to delete the file with that strange name. Does anyone have an idea what it is?!

Stick it up on a file sharing site (Dropbox or even just in a zip on modyourpanties.com) and I'll take a look...

It's the 6.4MB CRES file - actually 6.6MB in this case, for some reason - which is sometimes packaged up with custom sims due to a game bug. It contains the CRES resource for every single item of basegame Bodyshop content. Sim creators are supposed to delete it if it gets included with their sims, but a lot don't do so - which is one of the reasons why it's important to always check downloaded sims with Clean Installer before you install them.

Oh! I know what this is. 6.65 mb - I know that file size. We've seen it for ages, but never knew what it did, if anything, or why it sometimes got attached to sims... It comes with different names than just this one but would be the same file size, if you wanted to check for more. But you got it along with a sims2pack file sim. You can even get multiples on the same sim, with different names - seen that a couple times.

What it is is... all the skeleton reference files for every item in the base game. It's a stuff that lives in a different form in Program Files, and while I've never known it to be harmful before, I suppose if it became corrupted or somehow incorrect vs. the originals it could cause crashing.

I think for a while, once we noticed it, we made people take it out of their sims2pack file if we noticed it in there when checking for CC when moderating sims here, but I'm not sure if that's been a thing for a while, or if we went, "Well, it's not known to be harmful and it's hard enough getting people to track down hair without requiring people to remove stuff that we're not even sure what it is..." or what...

Can you describe the circumstances of the crashing? Because if those 6.65mb CRES-ful files are actually potentially crash-causing then this needs to be properly documented, made known (because people will definitely have them, they're quite common in sims2packs containing sims), and an easy way to remove them from all one's various subfolders found.

I still ask creators to remove it, because it's not CC that they used on the sim, so it falls under "unused content in sims2pack".

Well I have been getting the crashes for such a long time I actually thought that my computer was just not friendly with The Sims 2, so I just kept playing and saved my game often, trying to make the best of it. After installing The Sims 2 UC I entered Desiderata Valley and played with Natasha Una for a few minutes, just to playtest. She picked up her phone to call Elizabeth Aspir just to chat, and that was when the game started crashing again.

Then it came to my mind that last time I played Desiderata Valley my sim had a lot of contact with Elizabeth Aspir, and that was a period when the crashes happened often. I also noticed that the crashes depended on what kind of lot type I was playing on, crashes hardly happened on some lots, like in the Curious household in Strangetown, but often in the household of John Mole, for some reason.

Since the crashes could take five minutes to three hours to show up I found it really hard to figure out what the problem was, I tested lowering my graphic settings, clean out some CC (mostly the ones with the name default) etc. but the crashes still happened. I noticed (this yesturday) that no matter what you did, the Aspir household would always crash when you tried launching it. Removing the whole Downloads folder and then launching the Aspir household, without problem, gave me the idea that it was CC that was the trouble. Doing the whole 50/50 method, Aspir was the household I always opened during the method. If it crashed, then I knew that the bad CC file was in the Downloads folder and I could just keep splitting the CC up until it was clear to me that uhkjhihjkj (11) file was the one causing the crashes.

NOTE: I'm not saying Elizabeth Aspir is corrupt or anything, because these crashes happened in Pleasantview too!

It sounds like Elizabeth was wearing a basegame item, whose CRES in the dodgy file was damaged or corrupted for some reason.

That explains sooooo much

Hello, I also have seen this file and have speculated that it causes crashes in my version of Sims 2 UC. Today, as I ran through my download folder with Clean Installer, several of the files from the creator at http://sims2bestcity.blogspot.com/ included the file "uhkjhihjkj (11)", which is 6.64mb.

About the crashes:
- As above, calling a specific sim located on the second page of the phone book caused a crash to desktop. (In this case, a sim created by me. Interestingly, I don't think she was wearing anything related to the creator above, and I could pop into her lot and play fine.)
- Crashes would occur more often on community lots. Should be noted that my sim could spawn on the lot just fine.
- Uneducated speculation: I believed that there's another sim wearing some custom content that I hadn't pinned down causing the issue.
- Time until crash otherwise would vary. Never during a Sim night.
- This week, the CAS would not allow me to create elders with gray hair. Bodyshop also crashed a couple times. (Which is why I'm going through with Clean Installer. To be really safe, because CAS is now not letting me create an elder with gray hair, I'm reinstalling everything.)

There's no need to reinstall, these kinds of problems are almost invariably caused by CC - in this case probably that silly file, but there could be other dodgy files in your Downloads if removing the CRES file didn't help.

Yes, I realize that this is a very old post. But I will put the last nail in it's coffin as this will always be an issue, especially for new comers to this OLD game. The majority of time these files reside in Sims2Pack files. When you install a sim they get installed in your game with the Sim.
The name can be anything, uhkjhihjkj (11), b18484e15a91c5a039d61f635d15d7c3, fd0550dd59f39de820ea7e74dd7b8b1b...anything! The big give away is the size, it NEVER varies but CAN show up slightly different for other people depending on the operating system and what you're viewing it with. You can find the exact size for your system by going to your base game folder and in the Sims3D folder look at the size of the Sims06.package file. Mine shows 6.807 MB, within are 1534 CRES files. The issue is that some of these files are overwritten by newer EPs , stuff packs or defaults. With this file in your downloads folder it can (depends on loading order) change them back to the older CRES files, causing various issues to your game, such as the appearance of corruption. Finding and deleting this file may fix your issue IF it's what was causing it. GS

PS If you use Delph'y Download Organizer this files MD5 is: E1EF9B22280589772F053E3EC1F4E43E
However, it's true MD5 is: 504ce4194b468240d07834a23be30728 if you use an MD5 tool or on-line checker.
After installing anything, checking for this file would be wise.

Coffin buried.
