This feature is implemented in the kernels of Linux, FreeBSD and Mac OS X operating systems, and allows metadata to be associated with the file at the file system level.

(Note that many early PC operating systems did not keep track of file times.) Other information can include the file's device type (e.g., block, character, socket, subdirectory, etc.), its owner user-ID and group-ID, and its access permission settings (e.g., whether the file is read-only, executable, etc.).Īrbitrary attributes can be associated on advanced file systems, such as NTFS, XFS, ext2/ ext3, some versions of UFS, and HFS+, using extended file attributes. Some file systems also store the file creation time, the time it was last accessed, and the time that the file's meta-data was changed. The time that the file was last modified may be stored as the file's timestamp. The length of the data contained in a file may be stored as the number of blocks allocated for the file or as an exact byte count. Other bookkeeping information is typically associated with each file within a file system. In others, file names are simple strings, and per-file metadata is stored elsewhere. In some file systems, file names are structured, with special syntax for filename extensions and version numbers. Directory structures may be flat, or allow hierarchies where directories may contain subdirectories. Whether the file system has an underlying storage device or not, file systems typically have directories which associate file names with files, usually by connecting the file name to an index in a file allocation table of some sort, such as the FAT in a DOS file system, or an inode in a Unix-like file system. By this file name a file can be further accessed. A file system can be used to organize and represent access to any data, whether it is stored or dynamically generated (e.g., procfs).Ī file name is a name assigned to a file in order to secure storage location in the computer memory. However, file systems need not make use of a storage device at all. This is the smallest amount of disk space that can be allocated to hold a file. Most file systems address data in fixed-sized units called " clusters" or " blocks" which contain a certain number of disk sectors (usually 1-64). The file system is responsible for organizing these sectors into files and directories, and keeping track of which sectors belong to which file and which are not being used. Most file systems make use of an underlying data storage device that offers access to an array of fixed-size physical sectors, generally a power of 2 in size (512 bytes or 1, 2, or 4 KiB are most common).

3.4 File systems under Microsoft Windows.

Often times you can work without add header | A adds line A to the HTTP header. Both Javascript and Python work this way. If none of the parameters is true, then iit returns false. In details: it returns the first true parameter (yes, it supports any number of parameters). or | A | B true if any of A or B are true. You can specify as many parameters as necessary. In details: in the true case it returns the last parameter. and | A | B true if both A and B are true. When A is true it expands to C and vice versa. if not | A | B | C same as if, but the logic is inverted. Remember to use quoting if you use macros in B or C (the body). How you tell A is true? A is true if it is not empty and not just a zero. When it expands to B, C is just discarded, and the vice versa. Logic and flow if | A | B | C if A is true, then it expands to B, else it expands to C.
