Edexcel GCSE Computer Science (1CP2) Exam Questions

Award up to two marks for a linked description such as:

• Keeps a record/index of where each file is stored on the disk (1) so that the file can be found and opened when it is needed (1)
• Allocates each file to a folder/directory (1) so that files used for the same purpose are kept together (1)
• Decides where on the disk each new file is written (1) so that it does not overwrite an existing file (1)
• Allocates space on the disk for a file (1) so that the file has somewhere to be saved (1)

Allow 'files are organised into folders so that they are easy to find', with the folder point (1) and its purpose (1).

Do not accept responses that only state that the operating system 'organises' or 'controls' the files, with no way of doing it given.

Do not accept 'stores the files' or 'saves files to the disk' without a way of doing it.

Do not accept responses about backing files up, or about the amount of storage space left on the disk.

Award up to two marks for a linked description such as:

• A storage limit/quota is set for each user account (1) so the drive is shared fairly between users (1)
• The operating system records how much space each user's files are using (1) and refuses to save more files when the limit is reached (1)
• Each user is given a fixed share/quota of the drive (1) so one user cannot use the space set aside for another (1)

Allow a limit set by an administrator or through the operating system's user management settings; an administrator is not required for credit.

Allow a warning that stops the save; do not award the development for a warning alone where the save is not stopped.

Do not accept responses about passwords/authentication, keeping files separate/folders with no storage limit, deleting old files, compressing files, or buying a larger drive.

Do not accept 'the operating system gives the user a bigger hard drive'.

Do not accept a single global limit for all users; the limit must apply to each user/user account.

Award up to two marks for a linked explanation such as:

• The operating system keeps a record of where each file is stored (1) so files can be found/retrieved later (1)
• The operating system keeps files in separate storage locations (1) so files are not overwritten/lost (1)
• The operating system allocates files to folders/directories (1) so it can keep track of the files stored on the disk (1)
• The operating system deletes/moves files (1) so storage space is freed/reused (1)

For both marks, the expansion must follow/associate with the statement.

Do not accept 'it manages files'/'it organises files' without expansion as to what is managed or organised.

Do not accept 'so files are managed/organised' as the linked reason.

Do not accept 'so the computer works' as the linked reason.
