Here are 2 methods for copying files in Delphi.
Method 1:
procedure FileCopy(const SourceFilename, TargetFilename: string);
var
s, t: TFileStream;
begin
s := TFileStream.Create(SourceFilename, fmOpenRead);
try
t := TFileStream.Create(TargetFilename, fmOpenwrite or fmCreate);
try
t.CopyFrom(s, s.size);
finally
t.free;
end;
finally
s.free;
end;
end;
Method 2:
procedure FileCopy(const SourceFilename, TargetFilename: string);
var
fromF,toF: file;
numRead, numWritten: word;
buf: array[1..2048] of char;
begin
AssignFile(fromF, SourceFilename);
Reset(fromF, 1);
AssignFile(toF, TargetFilename);
Rewrite(ToF, 1);
repeat
BlockRead(fromF, buf, SizeOF(Buf), numRead);
BlockWrite(toF, buf, numRead, numWritten);
until (numRead = 0) or (numWritten <> numRead);
CloseFile(fromF);
CloseFile(toF);
end;
