I guess you are looking for ExpandFilename, which expands a simple filename with the path (if that can be determinded)?

Maybe the following function will help you!

Findfirst();Findnext;Findclose;FileSearch();

You can get help's detail from delphi.
Good luck!

Hi,

Assume that you have a file name with full path. The ExtractFilePath will return the path name of that file.

To get a full name of a file, you can:

1. Use ExpandFileName or ExpandUNCFileName if you have a short file name. But remember that these two functions work only for files in current directory (for relative file name).

2. Use Findfirst();Findnext;Findclose;FileSearch(); recursively to build up the full path of the file that they found. When you found a directory and pass it recursively into inner level, you should store that directory and build up the path, so when you got a file name, its path would be already built and you can use it.

Regards,

extractfilepath is only useful if you have a known variable such as in the case:

FILEPATH:=extractfilepath(application.exename);

In this case extractfile will return where the application is present.

I will get back to on Find first find next example.

This is how you use findfirst and findnext:



var
 FileName: string;
 FindHandle:THandle;
 SearchRec:TWIN32FindData;
begin
 try
  FindHandle := FindFirstFile('C:\*.*', SearchRec);
//where C:\*.* specifys the Directory and the file extension that you want to find.
//It can be the full path too.
  if FindHandle <> INVALID_HANDLE_VALUE then
  repeat
   FileName:=SearchRec.cFileName;
   ListBox1.Items.Add (FileName);
  until FindNextFile(FindHandle,SearchRec)=false;
  finally
   FindClose(FindHandle);
  end;
end;

Regards,

IF you have no idea whatsoever as to where the file are located you will need to perform recursion using findfirst and findnext. This is very hard and i have no available code to show you. Your best bet is to use findfirst, findnext by specifying the directory and the files.

Hope all this helps,
