PSP file format is associated with PaintShop Pro, an image editing software developed by Corel. It is a proprietary format used for storing raster graphics created and manipulated within PaintShop Pro. PSP files support layers, channels, and various other advanced graphics elements, allowing for detailed and complex image editing. This format is primarily used for saving intermediate edits, enabling users to continue working on their projects with all elements intact.
THM files are video thumbnail files that contain a small image or "thumbnail" of a video file. They are usually generated automatically by media players or video transcoding software and are used to provide a preview of the video.
