This article contains detailed information about certain inventory features and advanced tips for managing and troubleshooting your inventory.

System folders 

A system folder is a special folder that can't be moved inside of other folders or deleted. To view the system folders: Click the Inventory icon on the toolbar. Select the MY INVENTORY tab. System folders have the following attributes: As the name implies, the system depends on these folders to sort and help you organize your inventory, therefore they cannot be deleted. The folder icon for a system folder has a hand logo. User-created folders are plain. They appear by default at the top-level of your inventory. If you wish to change this, click the Gear Icon at the bottom of the INVENTORY window and uncheck Sort System Folders to Top.  Inventory items you create, upload or receive are automatically sorted into an appropriate system folder, such as Objects, Textures, or Scripts. No inventory item type is restricted to a single system folder. For example, if you create a pair of pants in the Clothing folder, you're free to move it into another system folder, or to a folder within a folder in the Clothing folder.

Special cases:

• The Lost And Found and Trash folders are specifically for items you have lost or plan to throw away. You can right-click either folder and choose Empty Lost And Found or Empty Trash, respectively, to permanently delete everything inside the folder.
  • Lost And Found contains items that have been returned to you from being rezzed somewhere in Second Life.
• The Current Outfit folder has links to everything you're wearing, and actually shows the same items as My Appearance - Wearing.
• My Outfits contains individual folders, each with a icon and usually containing a complete avatar look. My Outfits folders can contain original items if you intentionally move them in here, but otherwise they contain links. Outfit folders themselves are not system folders; they can be moved outside of My Outfits. Learn more about creating outfits.

The Library

While the Library appears in your inventory and can be considered a system folder in some ways, you can't alter it or its contents at all. It contains stock content provided by Linden Lab for use by all Residents. The way this folder works is similar to a "shared drive" on your computer network. All Residents share the same content at any given time.

How to retrieve old Library items 

From time to time, Linden Lab adds, edits or deletes content from the Library to ensure that it remains a useful resource for all Residents.

To make sure that any changes to your Library cause a minimum amount of inconvenience, we've archived all of the content and made it available for you at any time at the following inworld location:

Simply click on the wooden box that says Old Library Content to retrieve a package containing all items that have been removed from the Library.

How to hide the Library

2. Choose Advanced > Show Debug Settings.
3. Type noinventoryLibrary. It autocompletes.
4. Select TRUE.
5. Close the Debug Settings window and restart the Viewer.

Reducing inventory clutter

If you find yourself with a large number of duplicate objects cluttering your inventory, you can use the following procedure to find and eliminate them:

1. Open your Inventory window by clicking the Inventory button at the side of your screen.
2. Enter the exact name of the duplicated item in the search bar at the top of the Inventory window, and press the Enter key.
3. Wait a few moments while Second Life indexes and searches your inventory. If you have a very large number of objects in your inventory, this step may take a few minutes.
4. Select all the duplicate items found in your search. Make sure to leave at least one for yourself!
5. Press the delete key.
6. To restore your normal Inventory view, click the X button in the search bar, or close your Inventory window and reopen it.

Tips for recovering lost inventory items

If an item mysteriously disappears from your inventory, use the the procedures below to locate it.

• Click the Inventory button on the toolbar and select the RECENT tab. Items returned since last log off will be stored here.
• Clear the Second Life Viewer's cache. 
• Search for the item by entering its name in the Filter Inventory field of the INVENTORY window.
• Search the Lost And Found folder.
• Search the Trash folder.
• Search folders listed at the top of the INVENTORY window.
• Your filter settings may be hiding some of your inventory items. To reset them, click the Gear icon at the bottom left of the INVENTORY window and choose Reset Filters.

How to find the UUID of an inventory item

If you make extensive use of LSL scripts, you may want to know the UUID (Universally Unique Identifier) of a texture or sound in your avatar's inventory. You can easily copy any inventory item's UUID to your computer's clipboard by right-clicking it and selecting Copy Asset UUID.

This method is great for finding sound and texture UUIDs, but is not always effective for other inventory types. Here is a short list of exceptions:

• A notecard's UUID changes every time it is edited and saved.
• There is no way to find an object's UUID until it is rezzed inworld.
• There is no way to find an LSL script's UUID while it is in your inventory.
• You must have full permissions on any inventory item to copy its UUID; this also applies to calling cards, which are by nature "no-transfer" items.

LSL has several detection functions that can help determine an object or avatar's UUID. If you are interested in learning to use LSL for this purpose, see the LSL Portal.
