What is an .LQM file?

.LQM is LG QuickMemo note

QuickMemo isn't officially available to download fo Android devices from other producers.

A typical lqm file represents memo saved in QuickMemo.

It is essentially a ZIP archive, which contains the following:

  • memoinfo.jlqm file that appears to be a JSON formatted text file that contains the actual note
  • metadata.mtd file that contains additional metadata
  • audios, videos, images folders that contain any attachments
  • and finally the drawings folder that contains captured stylus input

As far as we know, only the QuickMemo apps on LG smartphones can directly read *.lqm files.

How to convert:

No LQM converter exists, but you can use several workarounds to recover the note, or any other attached parts (images, multimedia etc.) from the file.
