  • File Systems
    File Systems Tanenbaum Chapter 4 Silberschatz Chapters 10, 11, 12 1 File Systems Essential requirements for long-term information storage: • It must be possible to store a very large amount of information. • The information must survive the termination of the process using it. • Multiple processes must be able to access the information concurrently. 2 File Structure • None: – File can be a sequence of words or bytes • Simple record structure: – Lines – Fixed Length – Variable Length • Complex Structure: – Formatted documents – Relocatable load files • Who decides? 3 File Systems Think of a disk as a linear sequence of fixed-size blocks and supporting reading and writing of blocks. Questions that quickly arise: • How do you find information? • How do you keep one user from reading another’s data? • How do you know which blocks are free? 4 File Naming Figure 4-1. Some typical file extensions. 5 File Access Methods • Sequential Access – Based on a magnetic tape model – read next, write next – reset • Direct Access – Based on fixed length logical records – read n, write n – position to n – relative or absolute block numbers 6 File Structure Figure 4-2. Three kinds of files. (a) Byte sequence. (b) Record sequence. (c) Tree. 7 File Types • Regular Files: – ASCII files or binary files – ASCII consists of lines of text; can be displayed and printed – Binary, have some internal structure known to programs that use them • Directory – Files to keep track of files • Character special files (a character device file) – Related to I/O and model serial I/O devices • Block special files (a block device file) – Mainly to model disks File Types Figure 4-3.

  • File Systems: Semantics & Structure What Is a File
    5/15/2017 File Systems: Semantics & Structure What is a File 11A. File Semantics • a file is a named collection of information 11B. Namespace Semantics • primary roles of file system: 11C. File Representation – to store and retrieve data – to manage the media/space where data is stored 11D. Free Space Representation • typical operations: 11E. Namespace Representation – where is the first block of this file 11L. Disk Partitioning – where is the next block of this file 11F. File System Integration – where is block 35 of this file – allocate a new block to the end of this file – free all blocks associated with this file File Systems Semantics and Structure 1 File Systems Semantics and Structure 2 Data and Metadata Sequential Byte Stream Access • File systems deal with two kinds of information int infd = open(“abc”, O_RDONLY); int outfd = open(“xyz”, O_WRONLY+O_CREATE, 0666); • Data – the contents of the file if (infd >= 0 && outfd >= 0) { – e.g. instructions of the program, words in the letter int count = read(infd, buf, sizeof buf); Metadata – Information about the file • while( count > 0 ) { e.g. how many bytes are there, when was it created – write(outfd, buf, count); sometimes called attributes – count = read(infd, inbuf, BUFSIZE); • both must be persisted and protected } – stored and connected by the file system close(infd); close(outfd); } File Systems Semantics and Structure 3 File Systems Semantics and Structure 4 Random Access Consistency Model void *readSection(int fd, struct hdr *index, int section) { struct hdr *head = &hdr[section];

  • File Allocation Table - Wikipedia, the Free Encyclopedia Page 1 of 22
    File Allocation Table - Wikipedia, the free encyclopedia Page 1 of 22 File Allocation Table From Wikipedia, the free encyclopedia File Allocation Table (FAT) is a file system developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. FAT as it applies to flexible/floppy and optical disc cartridges (FAT12 and FAT16 without long filename support) has been standardized as ECMA-107 and ISO/IEC 9293. The file system is partially patented. The FAT file system is relatively uncomplicated, and is supported by virtually all existing operating systems for personal computers. This ubiquity makes it an ideal format for floppy disks and solid-state memory cards, and a convenient way of sharing data between disparate operating systems installed on the same computer (a dual boot environment). The most common implementations have a serious drawback in that when files are deleted and new files written to the media, directory fragments tend to become scattered over the entire disk, making reading and writing a slow process. Defragmentation is one solution to this, but is often a lengthy process in itself and has to be performed regularly to keep the FAT file system clean. Defragmentation should not be performed on solid-state memory cards since they wear down eventually. Contents 1 History 1.1 FAT12 1.2 Directories 1.3 Initial FAT16 1.4 Extended partition and logical drives 1.5 Final FAT16 1.6 Long File Names (VFAT, LFNs) 1.7 FAT32 1.8 Fragmentation 1.9 Third party

  • Implementing File I/O Functions Using Microchip's Memory Disk Drive File

The MMC does not have a physical write-protect INTRODUCTION signal, but most card connectors will default to a non-write-protected state in this case.
