Convert LQM to TXT

An LG QuickMemo note may need to be edited in Notepad, indexed by desktop search, or preserved after the original LG phone is no longer available. Exporting its readable text to a TXT file makes that content accessible without the QuickMemo application.

What LQM is

LQM is the proprietary note format used by LG QuickMemo and QuickMemo+ on selected LG Android phones. An LQM file may contain typed text, handwriting, drawings, images, audio, timestamps, and other note metadata. It is normally created by exporting or backing up a memo from an LG device.

Many LQM files are ZIP-based archives with an .lqm extension, but the internal file names and structure vary between LG models and QuickMemo releases. In many versions, the typed note is stored in an extracted file named info.lqm, sometimes in a field such as DescRaw. That structure is not guaranteed for every LQM file.

What TXT is

TXT is a plain-text format containing characters without page layout, application-specific formatting, or embedded media. TXT files open in Notepad, TextEdit, code editors, document-management systems, and command-line tools. They are easy to search, script, copy, and archive.

TXT conversion preserves typed characters only. Handwriting, drawings, photographs, recordings, formatting, timestamps, and attachments must be exported separately from QuickMemo or retained in the original LQM file.

How to convert an LQM file to TXT

Extract it with 7-Zip on Windows

1. Make a backup copy of the original LQM file. Work only on the copy.
2. Install 7-Zip from 7-zip.org. Right-click the copy and choose 7-Zip → Open archive. If 7-Zip does not recognize the file, rename the copy from note.lqm to note.zip and open it again.
3. Extract the archive to a new folder with 7-Zip → Extract to “note\”.
4. Find info.lqm and open it in a text editor. If it contains readable structured text, locate the DescRaw value or another field containing the memo body. Some releases instead use a text, XML, JSON, or database file, so inspect the extracted files rather than assuming one fixed name.
5. Copy only the note text into a new document and save it as note.txt with UTF-8 encoding. Do not merely rename an image, database, or binary LQM component to .txt; changing the extension does not convert its contents.

For a command-line extraction on Windows, use:

7z x note.lqm -onote_extracted

If the command cannot identify the archive, make a copy named note.zip and run:

7z x note.zip -onote_extracted

Extract it on macOS or Linux

Test a copy of the file and list its archive contents:

file note.lqm
unzip -l note.lqm

If unzip reports a valid ZIP archive, extract it and search the result:

mkdir note_extracted
unzip note.lqm -d note_extracted
find note_extracted -type f

Open info.lqm or another readable candidate in a text editor, extract the memo text, and save a new UTF-8 file. A direct copy is suitable only when the extracted source is already plain text:

cp note_extracted/path/to/content.txt note.txt

Use the original LG application when extraction fails

If the archive contains only binary records, an application-specific database, or unreadable data, restore the backup to a compatible LG phone with QuickMemo or QuickMemo+ installed. Open the memo and use Share or Export if that version provides it, then copy the resulting text into a plain-text editor and save it as TXT. This is safer than guessing the internal encoding or editing database files.

Compatibility and quality limits

7-Zip can unpack a ZIP-based LQM container but cannot interpret every QuickMemo record. Some versions expose readable UTF-8 or UTF-16 text; others store it in compressed, encoded, or proprietary structures. An extracted info.lqm file may also contain metadata and markup that must be removed from the final TXT file.

Check the result for missing line breaks, replacement characters, truncated text, and unsupported symbols. If characters are corrupted, reopen the extracted source using the encoding indicated by its contents or metadata, commonly UTF-8 or UTF-16LE, then resave the cleaned text as UTF-8.

There is no consistently supported, general-purpose online LQM converter. Generic conversion sites may reject the file or treat it as an unknown ZIP archive, and uploading a memo can expose private content. Use local 7-Zip extraction or the original LG application; use an online service only when its current format list explicitly names LG QuickMemo LQM support and its retention and deletion terms are acceptable.
