데비안과 Windows 7이 모두 설치된 머신을 사용하기 시작했습니다. 그러나 일부 프로그램을 설치 한 후 공간이 충분하지 않다는 메시지가 나타납니다. 시스템에 총 1TB 이상의 하드 디스크 공간이 있다는 것을 알고 연구를했습니다. 루트 파티션은 5GB에 불과합니다.

Linux를 다시 설치하지 않고 특정 파티션에 더 많은 디스크 공간을 할당 할 수있는 방법이 있습니까?

아래에서 내가 실행 한 몇 가지 명령의 결과를 찾을 수 있습니다.

fdisk -l

또한,이 주제에 대해 자세히 설명하는 훌륭한 책에 대한 제안 (파일 시스템, 다양한 운영 체제가 파일 시스템을 이해하는 방법 등)도 감사하겠습니다.
