Arcsoft Album/Slide Show
From Just Solve the File Format Problem
ArchSoft PhotoStudio/Impression/PhotoBase software often came bundled with digital cameras for simple image editing on Mac and Windows.[1][2] Albums of collected images could be created for easy organization. Software would store the path to each image in album in a format with extension 'ABM.
File Information
ABM Album Files begin with the ascii string PALM for the first four bytes.
SLD Slide Show Files have the same format (PhotoBase v2) and describe the slide show parameters. File is dependent on a slideshow.exe executable and referenced image files.[3]
