Burn a Disc, Live File System vs. Mastered
Before burning a CD-R, Windows prompt user to choose whether Live File System or Mastered。 Live File System is USB flash drive alike, might not be readable OS before XP, can add, delete, ... files later。 Mastered is WRITE once, and then cannot add, delete, ... files later。

File Systems: Old Design
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。
| MSB | Base2: 23222120 | Base10 | Opcode | LSB |
| 0100 | 4 | READ | ||
| 0010 | 2 | WRITE | ||
| 0001 | 1 | EXECUTE |
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) (CDROM) (Write_speed) (Write_method) (...) ) (ISO (Length_of_file_and_directory (ISO_level_1 11B) (ISO_level_2 31B)) (Format_mode (Mode1) (Mode2/XA)) (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' ) ) ) (Multisession (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.

USB 2.0 Flash Drive: approx. 2544 aka 2000 ~ present
- plug and play, so it is portable, so it is also
embedded
- reusable storage, so copy | delete | write | ... data
- OS IFF Windows, ME | 2000 | XP | Vista | ...
- OS IFF Mac, 9.0 or later ...
- OS IFF Linux, Kernel 2.4 or later ...
- data capacity MB, GB, TB, ...
- IFF Windows ... startup should be Normal。 If startup is Diagnostic or
Selective, USB 2.0 Flash Drive might NOT be functional。 Also see:
msconfig。
