Yeah, but Fraps is both old and unmaintained... and this argument about size is absolutely HILARIOUS given Fraps only records in raw format or their proprietary codec which is at almost raw file sizes as it prioritized speed over compression so it ran at all on single-core CPUs of the time.
You won't record a minute of video with Fraps in a modern 3840x2160 display within 4 GB (Fraps splits video files in 4 GB because its just so old it's still designed with FAT32 in mind, I believe an option to disable the raw split was added in one of the last updates it ever saw), but I can do 10 minutes of HEVC 4:4:4 at a passable IQ with Action!. Honestly, Fraps is just obsolete and it's not only not recommended, but not cut to do the job anymore. If OP wants to use it anyway, all the power to him and on how to handle the absurd files it generates. But he is a stubborn fool repeatedly coming up with excuses to justify his deluded fantasy.
Shadowplay for Nvidia, ReLive for AMD, QuickSync on Intel, Action!, Playclaw, Bandicam, OBS Studio, MSI Afterburner... I think even the ancient and long forgotten Dxtory is ahead of Fraps
