ExpandFileName

unit
Sysutils
category
file name utilities

declaration
function ExpandFileName(const S: FileName): string;

description
Retrieves the full path and filename of a specified (relative) file.

The ExpandFileName function merges the name of the current drive and directory with the specified filename to determine the full path and filename of the specified file.
This function does not verify that the resulting path and filename are valid or that they refer to an existing file on the associated volume.

example
var AFileName, FullName : string;

AFileName  := 'myprog.exe';

ShowMessage(ExpandFileName(AFileName));
//displays 'C:\Program Files\Borland\Delphi7\Projects\myprog.exe'
// if 'C:\Program Files\Borland\Delphi7\Projects' current folder

SetCurrentDir('c:\Temp');
ShowMessage(ExpandFileName(AFileName));
//displays 'c:\Temp\myprog.exe'
