A rust library to monitor filesystem and more in windows.
See MINIFILTER.md for building the minifilter or just right click install using the .inf file
provided in releases.
You can also build using EWDK if you don't want to install Visual Studio, SDK and WDK.
NOTE: By default it is built for Windows 10 and above.
NOTE: Enable Loading of Test Signed Drivers by executing Bcdedit.exe -set TESTSIGNING ON in administrative cmd.
Use cargo run --bin minifilter --release to run the example application or just run the .exe provided in
releases as administrator (
for some reason the new default terminal on 2H22 is very, very slow
).
The program starts to print the IOMessage which is defined like:
```rust
pub struct IOMessage { pub extension: [wchart; 12], pub fileidvsn: culonglong, pub fileidid: [u8; 16], pub memsizedused: culonglong, pub entropy: f64, pub pid: culong, pub irpop: cuchar, pub isentropycalc: u8, pub filechange: cuchar, pub filelocationinfo: cuchar, pub filepathstr: String, pub gid: culonglong, pub runtimefeatures: RuntimeFeatures, pub filesize: i64, } ```
We end the process using ctrl + c in the example video:
The performance of the minifilter doesn't really exceed <1% of the CPU usage (I never saw it tickle even to 1% while
running scripts to make multiple temporary files). Although depending on you console if you try running
cargo run --bin minifilter --release you might see spikes reaching 1-3% but that is because of the console itself (
comment out the writeln! in the bin example) or try changing consoles (maybe run minifilter.exe directly).
