Use FileExists(Filename).

Try this:
MyINI := TINIFile.Create(ExtractFilePath(Application.ExeName) + 'MyApp.ini');

ExtractFilePath(Application.ExeName) will give you the directory that your
program was run from.

Good luck,

To execute a dos program I created a PIF file useing windows PIF editor.  I
then used the delphi windows command WINEXEC ('\dir\dir2\exec.exe', SW_????) ;

To check for files use the FILEEXISTS ('\dir\dir2\file.txt') ; command.  It
returns True or False ;

From the Delphi v2.0 Help file:

Declaration

function FileExists(const FileName: string): Boolean;

Description

The FileExists function returns True if the file specified by FileName
exists. If the file does not exist, FileExists returns False.

For an executable, 'Application.EXEName' contains the full path and
file name of the executable. What I do is use a small function that I
maintain in my set of "stock" units called GetDirectory. I pass the
EXEName property to the function, which simply steps backward through
the string until it hits a backslash, then returns
'COPY(InputString,1,BackslashPosition). You can use that return value
as the location for the program-specific .INI file (e.g.,
"INIFile.Create(ProgramDirectory+'XXX.INI')", where ProgramDirectory
is the return value from the GetDirectory function).

I hope this has been both helpful and clear (but I'd prefer helpful!)

Psst!  Here's a little secret, ExtractFilePath(Application.EXEName) will
do all that for you.  No fuss, no muss...

Look up the "FileExists()" function in the helpfiles.
