File.GetSize Examples

number File.GetSize (

Example 1

file_size = File.GetSize(_TempFolder .. "\\setup.exe");

Gets the size (in bytes) of the file "setup.exe" located in the user's Temp directory and stores it in the variable "file_size."

Note: _TempFolder is a built-in variable that contains the path to the user's system "Temp" folder.

Example 2

-- Searches for a specific file on the user's system.

location = File.Find("C:\\", "target.txt", false, false, nil);

if (location ~= nil) then

-- Check the size of the first file that was found.

file_size = File.GetSize(location[1]);

if (file_size ~= -1) then

-- See if the file is 25 bytes. Display a valid or invalid file message to the user.

if (file_size == 25) then

Dialog.Message("Success", "The file on your system has been validated.");

else

Dialog.Message("Failure", "The file on your system is not valid.");

end

else

Dialog.Message("Failure", "The file on your system could not be validated.");

end

else

-- Display a message that the target file was not found.

Dialog.Message("Notice","The file 'target.txt' was not found.");

end

Searches for a file called "target.txt" in the root of the C:\ drive. If the file is found, its file size is read and compared to the value 25 bytes. Based on the validation results, an appropriate dialog message is displayed.
