Inventory Management: Introduction

Hi, I’m Re, & I’m a pixel junkie. That’s right, I’m a hoarder of pixels!

Gadgets, toys, clothes, scripts, tools, sculpt maps, gifts from friends, pix, textures *shudders at the thought of loosing just one good texture….*, notecards, landmarks, you name it – I’ve come up with a reason to hoard them.

Odd, since in rl, I am the complete opposite, a true believer in ‘less is more’ but, there it is. The truth is told. I had to learn to do something with all those pixels if my avatar was going to be able to walk without holding the lag monster’s hand all the time!

In this tutorial you’ll learn tons of great ways to keep all your cool tools, toys, textures, & tinies – opps did I say tinies?

I don’t hoard tinies! I teach them Inventory Management skills! (Even tinies need to keep their tiny pixels in order.)

You won’t have to give up one single thing that you love to get your inventory size down to a size that doesn’t make the lag monster keep raising it’s ugly head.

    We’ll cover:

  • Power Tools: Learn how to use your Inventory Window faster & more efficiently
  • Clear Clutter: Clear your inventory visually & sweep away the clutter & learn to find duplicate items
  • Get Organized: Set up your inventory to make it a tool instead of just a pain…
  • Archiving: Using prims & notecards to store items you use less often


Lil’ Tidbit: Did you know that people from the U.S. & the U.K., although they both speak English, pronounce inventory quite differently? People in the U.S. pronounce it ‘in-vuhn-tohr`-ee’, while people from the U.K. pronounce it ‘in-vent`-ohr-ee’. Hear them here. =)

Getting your inventory organized can take time. Why go thru all the bother?

Overloaded inventories are one of the major contributors to the lag that you experience in SL. It can also contribute to problems with the asset servers locating & thus rezzing your avatar & clothing.

Builds go smoother when you can easily find textures & tools.

Giving things to friends will not be a hassle when you can find what you are looking for without having to search all over for them.

Getting your avatar dressed for an impromptu party or event will be a breeze.

Keeping track of friends, events, sales, & business will be simple.

Your tools, gadgets, toys, & animations will be close at hand.

In the end, every minute spent now, getting organized, will save you much more time.

Getting organized is a step-by-step process & you don’t have to do it overnight. Work on it when you aren’t busy or have a little extra time.

With a little effort each day, soon you’ll be sailing through the busiest of sims & the biggest builds with a smooth breeze at your back! And, by that, I don’t mean the lag breeze that can make your avatar sliiiiide around rather than walk!

Your Inventory


Your inventory is made up of System folders: folders that you start with when you first log in. These are the top level folders: Inventory & Library.


The library cannot be removed. The items in it are free items for getting started. You’ll find some great basics there.

System Folders

The top level Inventory contains system folders that store items of different types. When you receive loose items (items not sent contained in folders) they will go into these folders.

System Folders Items
Animations animations
Body Parts shape, skin, hair, eyes
Calling Cards calling cards
Clothing shirts, pants, shoes, socks, jackets, skirts, gloves, undershirts, underpants, alpha masks, tattoos, physics
Current Outfit things you are wearing including on your screen
Favorites landmarks you put on your favorites bar
Gestures gestures
Landmarks landmarks
Lost And Found items returned to you from inworld
Notecards notecards
Objects objects including prims & mesh
Photo Album snapshots you take with your viewer
Scripts scripts
Sounds sounds
Textures textures & snapshots sent to you by others
Trash items you delete from inventory or inworld
Viewer & World Folders Items
Received Items in some worlds for receiving items from their marketplace

#Phoenix a sign you are an ancient avatar indeed!
#InWorldz links to animations used in the built in AO
#RLV used when RLV is turned on

Note: Viewer specific folders are created when you use any viewer to log into your world. If visiting different worlds, you will have only the viewer specific folders for the viewers you’ve used to log into that particular world.

Assets & UUID’s

Asset Servers

The items in your inventory are stored on servers as ‘assets’. Sensibly, these special servers are called the ‘asset servers’.

Hard Drive Cache

A list of your items is also stored on your hard drive as your ‘inventory cache’.

To view your cache on your hard drive go to Preferences Ctrl-P (PC)/Cmd-P (Mac): Network & Cache tab: Click on the ‘Open’ button at the end of the Cache Location line.

Inventory Management 101 4 UUID

Each item, or asset, is assigned a UUID or Universally Unique Identifier. UUIDs are strings of numbers & letters that the servers may understand but most of us mere avatars read as gibberish!

‘d7ba08d1-7573-87f1-0f8d-840d7bf029b2′ or Girl Next Door Avatar Polka Dress Top – Pink’ – Which name makes more sense to you?

Instead, you get nice sensible file names for your folders & items in your inventory.

Because the UUID is the real identifier, & not the file name itself, we may give more than one item the same file name.

The UUIDs of each item will remain unique keeping the asset servers happy but sometimes confusing us.

Keep this in mind as you delete duplicate items. Files with the same name may be, in fact, not duplicates, but two unique items.

Why isn’t there something to search & destroy duplicate items?

If items with the same file name might not be duplicates, can’t they just make it so I can delete all items with the same UUID?

Sounds easy enough but, as it turns out, that wouldn’t work either.

UUID Changes

The UUID of some items change even if the item hasn’t been modified. Scripts get a new UUID every time it is copied, even if no changes are made. A prim changes UUID every time it is rezzed.

For items that cannot be changed inworld; animations, sounds, & textures; the UUID never changes.


It’s good to be aware of all this, especially if you script, but it is not necessary that you become a ‘puter genius to work with your inventory.

Inventory Button     Open Inventory Buttons

The first thing I’d like you all to do is log in to your world & open an inventory window. Click the ‘Inventory’ button with the suitcase icon in your bottom toolbar or use the keyboard shortcut Ctrl-I (PC) / Cmd-I (Mac) to toggle the inventory window open & closed.

Inventory Management This Is Your Inventory

If it’s the first time you’ve opened it in your viewer, you’ll get a popup telling you some pointers about your inventory. Read it & click ‘OK’.

Inventory Size FS
Look at the top left of the inventory window. You’ll see, just under ‘Inventory’ in the title bar, how many items you have. Some viewers have the size at the bottom of the window.

Inventory Management 101 2 Fetch Inventory

If you don’t see a number there, type an ‘e’ into your search box at the top of the inventory window. This will make your inventory size appear in the window title bar. If you see (Fetched…) at the end of the inventory size & the number keeps increasing, that means that the asset servers are downloading inventory to your computer.

How many items do you have? Under 20k? Fantastic! 20-30k? Pretty good. 40-60k? More than 60K? Let me look into my crystal ball: yeppers, you got a major issue with lag! Time to get to work!

Can you find anything you want, when you want it, without a big deal?

Regardless of where you stand right now, having a system to get and/or stay decluttered will assure that you can work faster & better now & forever.

TIP: Be sure to check your ‘Trash’ & ‘ Lost & Found’ folders when items appear to be missing.

When items seem to have become lost, it is sometimes because your cache on your hard drive has become corrupted.

If you suspect that you have lost inventory, try clearing your cache & fetching a fresh copy of your inventory from the asset servers.

Clear Cache V1.23

To find the location of your inventory cache on your hard drive or to clear it:

Preferences or Ctrl-P(PC)/Cmd-P(Mac): Network tab.

Clear your inventory cache in the window then close & reopen your viewer to complete the process.

It will take some time so be patient, in particular if you have a lot of items in your inventory. It’s a good idea to teleport to a low lag sim while you do this so your connection won’t be as busy downloading InWorld content as well.

This is not to be confused with clearing your ‘visible cache’. Your visible cache are the files that are downloaded to your computer temporarily for rendering things you see inworld in your viewer at the moment, which does not include the list of inventory items that are kept on your hard drive.
