If You want to know the length of the file then use .lenght() method of File class which return long.
ok.

Would you please give me simple example showing how to get the size of file?
Thanks,

My Code is here:
File f = new File("Test.txt");
long size = f.length();
This will give me size of the file but if it is 1 KB. If it is more than 1KB, it will give me 0. Why???
Thanks,
Angela

Hi
If you read the description of the method length(), it clearly says that the return value of length() will be 0L(long value) if it cannot find the specified file name on the disk. So in your example there may not be such file called Test.txt
If you need more clarification, then use exists() method.
