Just a small question from newbie

[Watchman3001]

Good morning. Just found this amazing program, and it seems really helpful. Just have a few questions I want to ask, just in case
Compressing via this program does not affect performance/loading times of any game?
Should the program always run in background? Like, when I close it, it says it is monitoring some folders. Should it stay on forever, and what happens if it is closed?
How it handles updates for the games? Are they going to be updated properly?
And also... Strangely, it doesn't seem to do much from many games from steam, at maximum getting rid of few GB at max. Like, at wiki it says warframe should lose quite a bunch of GBs, for me it loses a maximum of 3-5 GBs

Hope someone would be able to answer those small questions I have. Thank you in advance, and thank you for that great program you brought us!

Some games may take a performance hit when loading (usually very small) while others see a performance improvement (if they're disk-limited rather than CPU-limited for loading).

The monitoring in the background is just so you can keep track of which folders you've compressed; when they get updated by e.g Steam, their files aren't automatically compressed but CompactGUI can still detect that and show you which games you need to compress again. You can leave it running in the background, all it does is wait for Windows to notify it when a watched folder changes, so 99% of the time it's doing nothing at all.

Not every game will compress exactly the same, and the wiki doesn't distinguish between older and newer versions of games either. It's quite possible warframe used to be poorly compressed by default but the developers improved it over time.
