Reference Command Line

Command-Line Arguments

FindRomCover accepts optional command-line arguments to pre-fill the ROM and image folders. This is useful for launching the application from a launcher, a script, or a file manager.

Usage

FindRomCover [ImageFolder] [RomFolder]

On Windows the executable is FindRomCover.exe; on Linux and macOS use the FindRomCover binary.

Arguments	Behavior
none	Start with empty folder boxes; the previous session is not restored
one	The argument is used as the Image Folder
two	The first argument is the Image Folder, the second is the ROM Folder

Only existing directories are accepted. A path that does not exist is ignored. With one or two valid arguments the folder boxes are prefilled; when both folders are valid (the usual two-argument case), the scan starts automatically.

Examples

Start with only the image folder (Windows):

FindRomCover.exe "D:\Covers"

Start with both folders and scan immediately (Windows):

FindRomCover.exe "D:\Covers" "D:\ROMs"

The same on Linux or macOS:

./FindRomCover ~/covers ~/roms

Use it from a shortcut or batch file:

@echo off
start "" "C:\Tools\FindRomCover\FindRomCover.exe" "D:\Covers" "D:\ROMs"

Notes

• Quote paths that contain spaces.
• The scan uses the same logic as Check for Missing Images; the status bar shows the result.
• Folders passed on the command line are not restored on the next start. The ROM folder is not persisted at all, and the remembered image folder is used only for temporary-file cleanup at startup — see Data Storage.
• There are no other switches; all other behavior is configured through the application menus.
