LTK Tex Thumb Handler
LeagueToolkit's thumbnail handler shows .tex files as image previews in Windows Explorer. Sibling tool to Guisai's Tex Thumbnail Provider.
LTK Tex Thumb Handler is the LeagueToolkit team's Windows shell
extension. It shows .tex files as image previews in Windows Explorer.
It does the same job as Tex Thumbnail Provider by RitoShark. Pick one, not both.
What it does
- Shows
.texfiles as thumbnail previews in Windows Explorer. - Works on any folder with
.textextures (game files, exports, mod assets). - Runs as a registered COM DLL. No app to open. No background process.
Before you start
- Windows 10 or 11.
- Administrator access (the installer registers a system DLL).
- PowerShell.
Install
-
Close any Windows Explorer windows that show
.texfiles. -
Right-click PowerShell and pick Run as administrator.
-
Paste this command and press Enter:
iwr -useb https://raw.githubusercontent.com/LeagueToolkit/ltk-tex-utils/main/scripts/install-thumbnail-handler.ps1 | iex -
Wait for the installer to finish. It downloads
ltk-tex-thumb-handler.dll, copies it to%ProgramFiles%\LeagueToolkit\ltk-tex-thumb-handler, and registers it with Windows. -
Restart Windows Explorer (or restart your PC).
How to check it worked
Open any folder with .tex files. The icons turn into image previews. If
they still look like blank icons, restart Explorer or reboot.
Uninstall
-
Right-click PowerShell and pick Run as administrator.
-
Run:
regsvr32.exe /u "%ProgramFiles%\LeagueToolkit\ltk-tex-thumb-handler\ltk_tex_thumb_handler.dll" -
Delete the folder at
%ProgramFiles%\LeagueToolkit\ltk-tex-thumb-handler.
When to use this vs Tex Thumbnail Provider
Both tools do the same thing: show .tex previews in Explorer. Run only
one at a time.
| Tool | Made by | Install method |
|---|---|---|
| LTK Tex Thumb Handler | LeagueToolkit | PowerShell one-liner (admin) |
| Tex Thumbnail Provider | RitoShark | PowerShell one-liner (per-user) |
Pick LTK Tex Thumb Handler if you already use other LeagueToolkit tools. Pick the RitoShark version if you want a per-user install with no admin rights.
Warning. Don't install both. Two thumbnail handlers for the same file type can fight each other and leave you with no previews at all. Uninstall one before you install the other.
Troubleshooting
Thumbnails don't appear
Restart Windows Explorer. Open Task Manager, find Windows Explorer, right-click, and pick Restart. Open the folder again.
Still no thumbnails after a restart
Check that the DLL is at
%ProgramFiles%\LeagueToolkit\ltk-tex-thumb-handler\ltk_tex_thumb_handler.dll.
If it's missing, run the install command again.
Old Tex Thumbnail Provider DLL still registered
Uninstall the other thumbnail provider first. See the Tex Thumbnail Provider page for its install and removal steps.
Install script fails
Make sure PowerShell is running as administrator. The script needs admin rights to register the DLL with Windows.
Tex Thumbnail Provider
RitoShark's Windows shell extension shows .tex files as image thumbnails in File Explorer. Per-user install, no admin. See what is inside a texture at a glance.
