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.

User programs could neither make sure adherence to protection methods nor be trusted to allocate only free blocks and deallocate blocks on file deletion.
