Tutorial: How To Convert .Sims3Packs Then Decrapify and Compress

in Sims 3 Guides, Sims 3 Technical Stuff

When I’m installing custom content, I want .package files and that’s it. I don’t want to have to open the Launcher and hope it decides it likes me that particular day. From past experience, I’ve found my Launcher is an ass that likes to screw with me just because it can.

There are folks out there who refuse to use The Sims 3 Launcher and, instead, use a custom launcher or start their games directly from a shortcut they created. However, those are both posts–or maybe just one post–for a different time.

When you’re done with this tutorial you will have learned how to:

  1. Convert Sims 3 Packs to .package files and keep you from having to use the Launcher.
  2. Decrapify your .package files which just might repair some of them
  3. Compress your .package files to reduce file size

Let’s get some definitions out of the way.

  • Launcher/The Launcher–Evil bugger most use to start their game.
  • Convert–v. Cause to change in form, character, or function.
  • .Sims3Pack–File type that installs via the Launcher.
  • Decrapify–Helps Sims 3 packs suck less. Refers to decrapify.exe.
  • Compress–v. To condense, shorten, or abbreviate. Refers to s3rc.exe.

Standard disclaimer and stuff:

This is what I do with my game and the custom content I install. Just because it works for me doesn’t mean it’s going to work for you. In fact, it just might completely kill your game, melt your computer and cause you tons of mental and physical harm. You’ve been warned and you can’t blame me.

First things first, download the TS3 Recompressor from MATY.

Extract that somewhere. The where is really up to you but extract it into its own happy folder; there will be two files.

Download the S3PE [Package Editor]. Guess what that jobber does. You’re right! Edits that Sims 3 Pack you’ve downloaded. That dude’s going to need to install on your system so let it do its thing.

Thirdly, download Delphy’s Sims 3 Pack Multi-Installer [Multi-Extractor]. When you extract it, you’ll have yourself an executable file and make sure you extract it to somewhere you’ll be able to easily navigate to–like your Desktop.

DANGER Will Robinson!Word of advice here: If you have full sets or lots or houses you’re going to be decrapiying, create a folder for each set. When Delphy’s program gets a hold of the set, it’s going to extract a bunch of .package files and they’re all going to have insanely long “names” and you’re not going to know what goes with what. You’ve been warned.

Go find the custom content you downloaded. For today’s lesson, I’m using The Vintage Sim’s Kelly Pointe house. I’m going to assume you know how to extract files. Make a happy folder home for that content and copy the decrapify.exe and s3rc.exe files into that new folder to keep your custom content file company.

It should look something like this:


Double click on Delphy’s program, navigate to where your custom content is living for that first selection. For the second, choose where you want the extracted file[s] to live. I always let it rename the file to match what the original file was named since that makes my life easier. Like it says, this only works if it’s just one file like a shirt or something. Click “extract” and let it do its magic.

Sims3Pack Multi Installer Extractor

Holy damn that’s a lot of files!

With the house, this was the end product and as you can see, there are a lot of files. See why it’s good to have a folder for each set or house or lot?

Sims3Pack Multi Extractor Finished

Now you want the S3PE program. Go find it!

Here’s your chain of events; follow along.

File->New->Resources->Import->From package…

You should see something like this:

Import from Package

Reject duplicates. Damn posers.

Reject duplicates.

It’s going to ask you if you want to, “Auto-save current package after each package imported?” That’s up to you. Make your choice and then give the program a second to do it’s thing.

When it’s done make sure you save!

Save as...

Here’s what it should look like when you’re done with that part:

All done!

Click on the new .package file and drag it on top of decrapify.exe. A black box is going to pop up and then will disappear. The length of time that box is up is going to depend on just how crappy the file is.

Black box

Once that’s done, drag the file over s3rc.exe. Another black box is going to pop up. Let it do its thing just like last time.

This is what it should look like when you’re completely done:

I copied the file before I decrapifyied and compressed it so you can see the difference if file size. Just converting the file reduced the size a bit and though the end result isn’t a HUGE OMG difference, it is a nice bit of a reduction and when you have a bunch of custom content, every little bit helps.

Make sure you decrapify your saved games as well so the world doesn’t blow up and lots of people die. Because that would be sad. You’ll find your saved games here: C:\Users\[You]\Documents\Electronic Arts\The Sims 3\Saves.

Even if you decide you don’t want to deal with the second and third steps, converting .Sims3Packs to .package files keeps you from having to deal with the Launcher.

    great article and thanx for the tip but I am way to lazy to do it lol. I don’t use the launcher to play my game only to install store stuff and then I end task on the silly buggy resource sucking launcher

  • katawnasimpleton

    Hmmm when I am using the Delphy extractor, it only creates one file in my Sims3Packs folder. This is a large house that I created and has a lot of items as well as CC but only one of the 0x numbers show up like in your demonstration for that part? Im not sure why that step is not working properly. I have done the entire process a few times, but the house never shows up in my game and I never get more than one 0x number in that first step no matter how many different packages I try to change over. Any ideas or help would be greatly appreciated as I have been trying to find a way to avoid the launcher.

  • http://TasteLikeCrazy.com/ Amy @ Sims 3 Gamer

    @katawnasimpleton Have you tried going back and downloading the file again? Delete the one you have, get a new copy and then link me to it so I can see exactly what’s going on.


  • katawnasimpleton

    @Amy @ Sims 3 Gamer Yes those were new files actually just created. How can I link you to it?

    • columbia93

      I believe that, if it is a house you’ve created, you would only have the house file, regardless of CC. I’m guessing but it seems the program would recognize that you have the items and would see them as duplicates. I could be wrong – I’m working on right now figuring out how the game handles “duplicates” – like a Sim having a custom bracelet attached but me already having the bracelet in my game via .package (since .package and .sims3pack files are handled differently). Recently, I used the Multi-Extractor to extract the custom content from a Sim. I put the package files in my Mods file and opened the Sims3pack file with CUSTARD and saved only the sim (no CC). The game was able to take the Sim and apply the custom content from the Mod file. I’ll do a house next but they are much harder to see if the CC is included or not!

  • http://TasteLikeCrazy.com/ Amy @ Sims 3 Gamer

    Email me @ Amy.Tucker@sims3gamer.com with the url to where the cc is living and I’ll take a look. 🙂

  • katawnasimpleton

    @Amy @ Sims 3 Gamer Oh sorry, did you mean send you a link to the exchange where I got it? LOL I blame lack of sleep. I am tired today. For example, this is one of the houses I am trying to convert. It’s one of my own builds. I did a complete reinstall of all my games so I am trying to redo everything in a more efficient manner that doesnt drive me crazy this time…. which is why I was so excited when Jac posted this link! I really hope to be able to do this. The house has CC a plenty within it. http://www.thesims3.com/assetDetail.html?assetId=3455816

  • katawnasimpleton

    @Amy @ Sims 3 Gamer I tried a few of my houses, all of which have CC in them and I keep getting the same results in the first step. Usually only one 0x number shows up instead of a whole list. 🙁 So, even though I go thru the rest of the steps, I must be missing something simple that I am just not doing OR not doing correctly.

  • eHoney7

    Thank you SO much for this article! It works perfectly for me. The launcher and accompanying Origin are the bane of my gaming existence (lol). However, I have a question, I tend to download a lot of customs sims, and I know you can’t install those as .package files, they must be .sim and placed in the Saved Sims folder. My question is, would you happen to know how to convert a Sims3Pack to a .sim file? Thnak you in advance for any help you can provide. I really would love to not need the launcher… ever.

  • OscarSorensen

    This is pretty darn handy! Even if you already have the .package files downloaded and the corresponding .simspack files, doing it this way left me with a .package file size of just over 70mb for the month of updates whilst the downloaded .package file was well over 120mb. Considering that both the package files contain the same models and files this is a massive space saver almost halving disk usage and obviously some performance was spared in game! Great tutorial (Y)

      @OscarSorensen Thank you! Glad you like it. 🙂

    The only real trouble I’m haivng is that these tutorials aren’t complete. I see people having trouble and the help they get from MATY is name-calling, etc. I understand how to do the CC-I’ve been extracting sims3packs and repackaging them for quite some time, but I want to decrapify and there is no definitive tutorial on what exactly gets decrapified OTHER than custom content. I’m also not so sure what needs to be done, if anything, when you install new EPs, etc. Do I need to go through every folder in the Doc/Electronics Arts folder? I’m not interested in trial and error (also generally suggested at MATY) since I lost basically everything in an HD crash and am having to restart TS3 metaphorically half-way through the game. I’ve been spending the past few months just trying to get my CC redownloaded (I’m an addict), extracted, checked in-game, sorted and THEN repackaged I’m just totally antsy to finally get to playing again!

    • http://Sims3Gamer.com/ Amy @ Sims 3 Gamer

      I’m a CC addict, too. 😀 This is from the thread on MATY [http://www.moreawesomethanyou.com/smf/index.php/topic,15129.0.html ]:”If you decrapify objects, you must decrapify all of your SAVED GAMES (.nhd & .packages in your .sims3), PRESETS (userPresets.package), and LIBRARY.” 
      Hope that helps.

  • ken

    once i install the decrapify store content, am i able to update my “legit” version of the sims through the launcher?


  • ken

    nevermind, i found the video you did on updating the game.


  • planie

    Hi! Was going through this tutorial and got to the point where you’re importing the files into s3PE and get the following error message:

    Could not open package verylongstringforaname.package.

    Expected magic tag ‘DBPF’. Found ‘DBPP’.

    This happens with all the files I try to import. What am I doing wrong/have done wrong? Thanks in advance.

    • Siobhan

      I encountered this too but I found a way around it when I was playing around with the files (hopefully it works for others too).

      First thing I’d is drag the original (or copied version) of the sims3pack onto s3rc.exe. It would do its thing and then after, I’d extract the .package files using the multi-extractor and continue with the rest of the steps.

      It’s odd to be that compressing the sims3pack before doing everything else solved the issue for me but meh. Lemme know if this works!

  • PsychoChick966

    Hi Amy. I DL a LOT of CC, and I’ve been choosing the Sims3pack version rather than the package file version because I read that a if you have a lot of package files, it causes problems and lag. Have you experienced any lag? I have BOATLOADS of CC….BOATLOADS…last check, last year, was around 25-27 Gigs..and I’ve been DLing every single day since then…so god only knows what I have now. You still think package files are the way to go with CC, for me?

    • wheresmyumbrella

      Yes, packages are definitely the way to go. I recommend sorting them into different groups like lots, hairs, skins, clothes, etc. Then combine your packages (keep the singular ones) according to how you grouped them. I only have 25 packages and it loads so much faster than it did before I had everything separate.

  • Newb

    Hi, after I complete this process for a world, where do I put my single new LunarLakes.package? It’s not showing up in the game even though it is in the mods folder and worlds cache folder

    • wheresmyumbrella

      should be in C:My DocumentsElectronic ArtsThe Sims 3ModsPackages (this is windows 7) and make sure your resource file is correct. You can google Sims 3 resource file and find one to download and it’ll tell you where to put it.

  • Sarah

    So, in Sm3pe the only options I get under file are open package, refresh, close, and exit. I don’t know what I’m doing here

    • Sarah

      nevermind, I had the wrong program I guess

  • Elba Montes

    Hi I dont know if you’re still reading these, but I can’t import anything. I get the same message as the person in the last comment except for it’s a little different. At the end it says Expected magic tag ‘DBPF’. Found ‘ instead of Expected magic tag ‘DBPF’. Found ‘DBPP’. Also, my icons don’t have the S3PE logo, only the normal blank page package files one. Is there something I’m doing wrong? I’ve done all the steps and even put the original S3Pack on the s3rc.exe file to no avail. Thank you!
