Working with Files

Go Up to RTL

The RTL supports several ways of working with files. In addition to using file streams, there are several run-time library routines for performing file I/O. Both file streams and the global routines for reading from and writing to files are described in Approaches to file I/O.

In addition to input/output operations, you may want to manipulate files on disk. Support for operations on the files themselves rather than their contents is described in Manipulating files.

Note: When writing applications, remember that although the Delphi language is not case sensitive, other languages or operating systems might be case sensitive. When using objects and routines that work with files, the best practice is to be attentive to the case of file names.
