편집시 지속적으로 신규파일을 제작하는게 너무불편하고 짜증남. 기본 실행 어플로 선택했을 경우 파일을 어플 외부에서 직접 열 때 이 현상이 나오는듯 한데 결국 이 어플을 기본 실행 어플로 선택하면 안되는듯.

pdf 파일 원본 상태로 만져야할 일이 최근에 많아서 이것저것 프로그램 다 써봤는데 알pdf가 최고네요 무료인데 편집가능한건 찾기 힘든데 기능 지원해주고 파일 암호 제거하는 것도 앞으로 pdf 편집할때는 바로 이걸로 써야겠어요 좋은 제품 감사합니다

pc버전도 잘 쓰고 있고 다 너무 좋은데 모바일버전은 파일을 열면 복사파일이 하나 더 생성되네요. 이거 하나 때문에 어플을 못쓰고 있어요.. 파일 하나에 100메가 200메가 300메가 이런거 쓰는데 그 파일들이 복사가 되면 어떡합니까ㅜㅜ 용량 작은 파일들도 다운 순서랑 날짜가 되게 중요한 상황인데 알pdf 썼다가 뒷목잡고 쓰러지는줄 알았어요. 파일정리 다시했어요.. 업데이트 좀 해주세요 ㅠㅠ
