Q. Explain the File-system manipulation?
File-system manipulation there is several details in file allocation, creation, deletion and naming that users should not have to perform. Blocks of disk space are utilized by files and must be tracked.
Deleting a file requires eliminating the name file information and freeing the allocated blocks. Protections must as well be checked to assure proper file access. User programs could neither make sure adherence to protection methods nor be trusted to allocate only free blocks and deallocate blocks on file deletion.
