There is still a language problem here.  What do you mean by the word "income"?

Where is this VI being run?  Is it a Windows PC, a real-time PC, a compact fieldpoint or compact RIO?

Assuming it is Windows, if you put your flash card into your drive, does it show up as a drive letter?  Generally, flash cards aren't going to show up as a drive D:.  More likely F, G, H, I, J ...

What are you trying to do with this VI?  It makes no sense.  If the file exists, your True case runs.  It reads the file, does some string and array manipulation.  And it will do this once.  But you have an embedded while loop that runs for ever at full speed for as long as that file exists.  Which means the VI will run forever.

Program has been read a file in flash memory and consistently determine the date, time and specify the Port if any pepole put flash memory in usb ports?

This project is a protection system that utilizes flash memory as a key to enter doors. The develop and designed system can determine the identity of the person allowed to enter and determine the time and the specified door; it will also records the registration of time and place, and keeping data in a file. The name of the person, time and door location will then be emailed to supervisor of the system. This system can be used in small homes as well as big organization.

Hi nawaf,

as I also don't speak English natively I would recommend you consult someone to help you better phrase your questions! It is very hard to understand what you really need...

Hint:

You can use the "List directory" function with an empty path input to get the names (letters) of the currently mounted drives (given at the directories output). When you do this in a loop continuously you can recognize the mounting of an USB memory stick. Then you also know which drive to check for any ID files or whatever.
