JLECmd Skill

JLECmd is Eric Zimmerman's command-line tool for parsing Windows Jump List files. It processes both AutomaticDestinations and CustomDestinations jump lists, extracting linked file metadata, timestamps, interaction counts, and embedded LNK data. Forensic interpretation of jump list data (user activity reconstruction, application usage analysis, etc.) belongs in a separate analysis skill.

Command Syntax

JLECmd.exe -f <file> [--csv <dir> | --json <dir> | --html <dir>] [other options]
JLECmd.exe -d <directory> ...

Single-letter options use a single dash (-). Multi-character options use double dashes (--).

Input (one required)

Flag	Description
-f	Single jump list file to process
-d	Directory to recursively process for jump list files

Output Formats

Flag	Description
--csv	Directory to write CSV output
--csvf	Custom filename for CSV output (overrides default)
--json	Directory to write JSON output
--html	Directory to write XHTML output

It's recommended to specify at least one output format to write results to a file. Forensic output can be very large and may consume the context window. CSV is the most common choice for analysis with Timeline Explorer or Excel.

Options

Flag	Description	Default
--all	Process all files in directory, not just jump list patterns	FALSE
-q	Suppress per-file output; show only filename being processed	FALSE
--ld	Include more information about linked files	FALSE
--fd	Include full information about linked files	FALSE
--withDir	Show directory contents not represented in DestList entries	FALSE
--appIds	Path to file with AppID mappings (format: appid|description)
--dumpTo	Directory to export embedded linked files to
--pretty	Use human-readable layout for JSON export	FALSE
--dt	Custom date/time format string	yyyy-MM-dd HH:mm:ss
--mp	Display higher precision timestamps	FALSE
--cp	Code page for string parsing	1252
--debug	Show debug information	FALSE
--trace	Show trace information	FALSE

Common Output Fields — AutomaticDestinations (CSV)

Workflow Examples

Parse a single jump list file to CSV

JLECmd.exe -f "C:\Cases\Evidence\5f7b5f1e01b83767.automaticDestinations-ms" --csv "C:\Cases\Output"

Parse a directory of jump list files

JLECmd.exe -d "C:\Cases\Evidence\Recent\AutomaticDestinations" --csv "C:\Cases\Output"

Parse with custom AppID mappings

JLECmd.exe -d "C:\Cases\Evidence\Recent" --csv "C:\Cases\Output" --appIds "C:\Tools\AppIDs.txt"

Parse with full linked file details

JLECmd.exe -d "C:\Cases\Evidence\Recent" --csv "C:\Cases\Output" --fd

Export embedded linked files

JLECmd.exe -d "C:\Cases\Evidence\Recent" --csv "C:\Cases\Output" --dumpTo "C:\Cases\Output\LinkedFiles"

Parse with high precision timestamps

JLECmd.exe -d "C:\Cases\Evidence\Recent" --csv "C:\Cases\Output" --mp
