Reads a file and computes the length of a file by reading through all the data in the file.
<integer_variable>= File.ComputeLength ( path )
Prerequisites
None
Parameters
path
A required String expression that contains the path to the file that is to be read.
Remarks
This function permits a GPL program to detect if a file has been changed or corrupted by computing its length so that it can be compared with the length in the file directory.
If the lengths match, the disk file allocation table is likely valid, but there is no guarantee that the actual data is unmodified.
Examples
Dim len As Integer len = File.ComputeLength(path) Console.Writeline("Computed length is " & CStr(len))
