How can I use TFile in Delphi

TFile is a class in the IOUtils unit that provides a set of static methods for working with files. You can use these methods to perform various operations on files, such as creating, deleting, and renaming files, as well as reading from and writing to files.

Here are some examples of how you can use TFile in Delphi

To create a new file, use the Create method;

TFile.Create(‘CMyDirectoryMyFile.txt’);

1	TFile.Create(‘CMyDirectoryMyFile.txt’);

To delete an existing file, use the Delete method;

TFile.Delete(‘CMyDirectoryMyFile.txt’);

1	TFile.Delete(‘CMyDirectoryMyFile.txt’);

To rename an existing file, use the Move method;

TFile.Move(‘CMyDirectoryMyFile.txt’, ‘CMyDirectoryMyNewFile.txt’);

1	TFile.Move(‘CMyDirectoryMyFile.txt’, ‘CMyDirectoryMyNewFile.txt’);

To read the contents of a text file into a string, use the ReadAllText method;

var
  FileContents: string;
begin
  FileContents := TFile.ReadAllText(‘CMyDirectoryMyFile.txt’);
   //Do something with the file contents
end;

var

FileContents: string;

begin

FileContents := TFile.ReadAllText(‘CMyDirectoryMyFile.txt’);

//Do something with the file contents

end;

To write a string to a text file, use the WriteAllText method;

var
  FileContents: string;
begin
  FileContents := ‘This is the contents of the file’;
  TFile.WriteAllText(‘CMyDirectoryMyFile.txt’, FileContents);
end;

var

FileContents: string;

begin

FileContents := ‘This is the contents of the file’;

TFile.WriteAllText(‘CMyDirectoryMyFile.txt’, FileContents);

end;

You can find more information about the methods provided by TFile in the Delphi documentation.
