The pgf file is actually a cache file generated by the on-demand function of PPS Internet TV (now renamed iQiyi PPS).
ppsds.pgf is mainly used for buffering during on-demand video, making the buffering time shorter and opening on-demand video faster. 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.
Can the pgf file be deleted?
ppsds.pgf will not have any adverse effects on our system. The only unpleasant thing is that it takes up nearly 1G Space. At this time we can find it and delete it by displaying the system file. If you don't want this file to appear in the future, then don't use the on-demand function of PPS Internet TV, then this kind of thing will not happen.
