 ### Benchmarking Local Files
 
-Our benchmark suite includes tests on local files and directories. These benchmarks are located in the [`benches/`](/benches) directory. Each benchmark sets a time limit using `group.measurement_time()`, which you can adjust manually based on your requirements.
+Our benchmark suite includes tests on local files and directories. These benchmarks are located in the `benches/` directory of some crates. Each benchmark sets a time limit using `group.measurement_time()`, which you can adjust manually based on your requirements.
 
 You have the flexibility to benchmark specific files or folders by modifying the variables within the benchmark files. By default, the benchmarks operate on the [`testdata/`](../testdata/) directory and its contents. You can change the directory/files by setting the `DIR_PATH` and `FILE_PATHS` variables to the desired values.
