File Systems: Old Design 2

File Systems: Old Design 1

File system vs. File extension

File system and file extension are syntax vs. semantics alike. The following concept should be applied to understand file system vs. file extension.

All men are human. All women are human. All human beings are not men.

File system interface vs. I/O interface

Basically, OS internal functionality can be categorized into interfaces such as file system interface, I/O interface, and etc.

FAT, NTFS file system compression vs. conversion

Files compression can be done by compact; Also see: compression ratio;  i.e. %PATH%\compact /? <enter>; Compressing file, file + dir, does not concern volume, but conversion [also see: converter] does i.e. %PATH%\convert /? <enter>; Text converter vs. File converter; Microsoft cabinet maker is makecab, diantz, ... ; convert is one of the parameters of diskpart in Win XP;

Extended partition disk region, Free space disk region, Logical drive disk region, Mirrored volume disk region, RAID_5 volume disk region, Spanned volume disk region, Simple volume disk region, Striped volume disk region, Unallocated disk region, and Primary partition disk region can be set in FS; Also see: MMC Console Mode;

Functionality such as FAT XP OS cannot deploy CD-R Recording parameter to NTFS Vista OS, for example, connect SimpleTech USB portable drive to a notebook with FAT XP OS, and also connect SONY USB portable DVD /CD-ROM drive aka DVD CD burner to the notebook, and then Explorer >> right click on the USB portable DVD /CD-ROM drive >> Properties >> General|AutoPlay|Hardware|Sharing|Recording, and click on the Recording, set parameterized value to USB portable drive [for example: SimpleTech (F:) ], and notice that OS with FAT cannot deploy such parameterized value because FS diff, because FAT cannot WRITE to NTFS;

File Permission:  UNIX related OS, Operating Systems' web directories

3 types: Group = Security group, WHERE users are classified / separated / divided / ... ; Other = world / anyone / everyone / any connectivity; User = owner of file;

4 = r = READ; 2 = w = WRITE; 1 = x = EXECUTE; Basically, 7 = read + write + execute, 5 = read + write, and so on ... ; If NOT read OR write OR execute, No permission; If neither read NOR write NOR execute, NO permission;

IFF User   Group   World are configured as rwx   rwx   rwx WHICH represents 777 permission, and can also command as: chmod 777 filename <enter> ; i.e. assume that a web developer has been configured as: a User permission rwx, Group permission rwx, and World permission rwx, on the other hand, people WHO browse the web have been configured as: User permission r-x, Group permission r-x, and World permission r-x, because people WHO browse the web do not need WRITE = w = opcode;

@ mutual exclusion algorithm becomes very very important among client and/or server WHILE set { ... } is TRUE;

File system constraints: (Label (Joliet) (ISO9660 (Volume _label) (System _identifier) (Volume _set) (Publisher) (Data _preparer) (Application) (Copyright _file) (Abstract _file) (Bibliographic _file) (ISO9660_text_for_Joliet)))  (Dates (Volume _date (Volume _creation) (Volume _modification) (Volume _effective) (Volume _expiration) ) (File _date (Original _stamp) (Current _system_stamp) (User _defined _stamp)) ) (Miscellaneous (Cache _file_from_drive) (Cache _file_size) ) (Drive (Speed) (Simulation _mode) (Write) (CD ROM) (Write _speed) (Write _method) (...) ) (ISO (Length _of_file_and_directory (ISO_level_1  11B) (ISO_level_2  31B)) (Format _mode (Mode1) (Mode2/X A)) (Character _set (ASCII) (DOS) (ISO9660) ) (Joliet (Unicoded_2nd_volume_descriptor_and_directories) ) (ISO _restriction (Directory _pathdepth  >8 ) (Maximum _character_of_path  255 ) (ISO _file_version_extension_char  ';1' ) ) ) (Multi session (Start _multisession) (Continue _multisession) (No _multisession) (Option (Compilation (Archive _bit_set) (File _date_stamp_changed OR File _length_changed) (File _content_changed) (Always _replace_file_in_compilation)) (Remove _deleted_file_from_compilation) (Add _new_file_to_compilation) (Refresh _compilation_prompt) ) ) ; Note: Constraints are commonly in parameterized, therefore constraints are either reference or value. But, file open, file close, file manipulation methods may vary depending on programming language compilers.
