It's not quite an issue that affects me playing the game. I want to understand what exactly is going on here.
After a certain patch, the game file was reduced to somewhere smaller than 50GB(without HD texture), I guess you guys know that. But since an update in early December last year, I find out my game folder is getting bigger and bigger, I am quite curious about this, so I decide to fully reinstall the game and try to find out what causes this. And I do find something there are a lot of files which names starting with somaething like a timestamp and ending with "StreamInfo.tmprec", "FrameDataStream.tmprec" and "StaticData.tmprec". They come up in groups, I mean for the same timestamp they have 3 different files ending with names mentioned before. For example a group of whole name of those files are "P15440_50_Y2022_M1_D16_H23_M58_FrameDataStream.tmprec", "P15440_52_Y2022_M1_D16_H23_M58_StaticData.tmprec" and "P15440_46_Y2022_M1_D16_H23_M49_StreamInfo.tmprec".
Those sound like they are kind of related to the game replays, but first, they are not located in "MatchReplays" folder under game folder(I mean "Tom Clancy's Rainbow Six Siege" folder), and second , after a small patch update I can't find like 1 to 1 match up between those files and my replays, and matchreplays only have 12 games at one time. I have like all this files since I reinstall the game. They are in total more than 6 GB! Thats quite a lot and they are growing when I play the game.
I want to understand what are these and if I can delete them.
