Can you try this:

1. Open the folder in file explorer
2. Right click in an empty part of the window and click Open in Terminal or if that doesn't show up then Shift+RightClick and select Open Powershell window here
3. Type in compact /c /s /exe:xpress4k

After it completes you should get a message like:

259 files within 18 directories were compressed.
1,140,951,619 total bytes of data are stored in 521,227,243 bytes.
The compression ratio is 2.2 to 1.

help! your file compresser does not compress anything, it always compresses by ~0-1% Game is installed on disk D. I have tried actions written above. It didn't help

Not all files can be easily compressed, and some files have really bad side effects if they do get compressed. There is a reason the program doesn't just try to compress literally every file.
