If you install the latest version of PPS Internet TV without using the on-demand function, ppsds.pgf will not appear. But as soon as you use the on-demand function of PPS Internet TV for the first time, a hidden file ppsds.pgf will be generated in the root directory of the PPSTREM installation hard disk. Of course, the pgf file will occupy a certain amount of space. This is why users see that the pgf file size is 1G or more. The reason is several gigabytes.
