What is an LQX file?

An LQX file is a memo created by QuickMemo+, an app installed on select LG smartphones. It contains an image, as well as annotations made to that image. Typically, the images that LQX files contain are screenshots from a user's phone or tablet.

Certain LG devices, such as the G7, Phoenix 4, and Escape 2, come with QuickMemo+ pre-installed. This LG-exclusive app allows users to take a screenshot and write or draw on it, before saving it as a memo. These memos are saved as LQX files.

While LQX files appear as a single image in QuickMemo+, they are actually renamed .ZIP files, which store a memo's constituent image layers and metadata files. Thus, if you do not have access to QuickMemo+, you can rename an LQX file to use the .zip extension and extract its contents as you would any ZIP file.

Each LQX file's contents include:

  • An images directory, which contains the original, screenshotted image and the final, annotated image
  • A drawings directory, which saves a copy of the user's annotations
  • A .JLQM file and an MTD file, which contain memo metadata

How to open an LQX file

You can open LQX files with LG QuickMemo+ (Android). On a device with LG QuickMemo+ installed, double-tap your LQX file or use the Open with feature to open your LQX file in QuickMemo+.

If you do not have access to QuickMemo+ and want to view an LQX file's contents:

  1. Rename the file to use the .zip extension.
  2. Decompress it using 7-Zip (Windows), Apple Archive Utility (Mac), or any other Zip-decompression utility.

Then, you'll be able to view the images and other data your LQX file contains.
