Line Work uses the LW file extension for bitmap images saved in tiff format. The file contains raster image data.
Line Work appears to be obsolete software and is no longer supported by its developer or distributor.
Because an LW file stores an image in TIFF format, try opening it with an image viewer or editor that supports TIFF files. If it does not open normally, the original Line Work software may be required.
A TIFF-compatible image editor or converter may be able to open the LW file and export it to a common bitmap format such as JPEG, PNG, or TIFF.
