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.

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
