About File Management
The following topics contain more information about file management.
In this section
|File System Functionality Comparison
||Tables that list functionality and feature support comparisons for the four main Windows file systems, NTFS, exFAT, UDF, and FAT32.
|Files and Clusters
||A file is a unit of data in the file system that a user can access and manage.
|Creating, Deleting, and Maintaining Files
||Functions to use to create, delete, and maintain files.
|Obtaining and Setting File Information
||Functions to use to get and set file information.
|Reading From and Writing to Files
||An application reads from and writes to a file by using the ReadFile, ReadFileEx, WriteFile, and WriteFileEx functions.
|File and Directory Linking
||There are two types of links supported in the NTFS file system: hard links and junctions.
||A block clone operation instructs the file system to copy a range of file bytes on behalf of an application.
|File Compression and Decompression
||The NTFS file system uses Lempel-Ziv compression, which is a lossless compression algorithm.
||The Encrypted File System (EFS) provides cryptographic protection of individual files on NTFS file system volumes by using a public-key system.
|File Security and Access Rights
||Because files are securable objects, access to them is regulated by the access-control model that governs access to all other securable objects in Windows.
|Input and Output (I/O)
||Windows provides the ability to perform input and output (I/O) operations on storage components located on local and remote computers.
||File compression of files that contain mostly zeros makes efficient use of disk space.
||A symbolic link is a file-system object that points to another file system object. The object being pointed to is called the target.
