What is a WLM file?

A WLM file is a raster image created by Paralelo Computação CompW, an image compression program. It contains an image that has been compressed using wavelet compression. WLM files can be embedded in OLE-compliant documents, but can be viewed in those documents only if you have CompW installed.

More Information

CompW is a suite of applications that allows users to compress images using wavelet compression, view those images online, and embed them in documents. Paralelo Computação is defunct, so CompW is discontinued and WLM files are uncommon.
