File Manipulation

MrK

I need to write a program to update a nother program. I need to find out if a certain directory exists, then if a certain file in this directory exists and then replace it.

Question: Where can i find units/functions that can do the file manipulations/searches I need to do?

To check if a file exists you need the FileExists() function in the SysUtils unit. The DirectoryExists() in FileCtrl unit checks if a directory exists. Alternatively you can also use the FindFirst(), FindNext() and FindClose() functions (also SysUtils). As far as I know are all these functions standard parts of Delphi.
