I'm trying to write a small program that will read all the files in a directory search for a certain word, if the word is found inside the text file, the program will copy the line containing the word into another text file.

I have no problem doing this on ONE file, my question is, is there a way to make the program go throught all the files with a certain extension (let's say .txt) found in a directory.

ie : is there a way to give Delphi 2.0 program the path to the directory and tell it to execute a block of code on '*.txt'

so if the directory I want searched is c:\list
and it contains the 20 files (or more) with the 'txt' extension, I want the program to go throught each one of those 20 (or more)files.

Thanks in advance

Use the functions 'FindFirst' and 'FindNext'. This functions support wildcards.

when you call findfirst and findnext, the results are entered into a record of type TSearchRec, which includes data about the current file (name, size etc.).

then you call the append and set the appropriate field to
(name of TSearchRec).Name

from delphi help:
-------------------------
Unit
SysUtils
TSearchRec defines file information searched for by FindFirst or FindNext.

type
TFileName = string;
TSearchRec = record
Time: Integer;
Size: Integer;
Attr: Integer;
Name: TFileName;
ExcludeAttr: Integer;
FindHandle: THandle;
FindData: TWin32FindData;
end;
