check that memory card is present in device or not

[kiwagh105@gmail.com]

 I am implementing one software to operate meter, in this I have to save data into the memory card before writing data on memory card(Removable) , I want to check if memory card is present in the device or not ? I am very new in LabView please help. best if post data diagram. Thank you in advance.

use these vis to see if there is such path in your system or not 
htey are in file I/o branch

Hey, 

 Are you using a cRIO ? Anyways, you could try looking at this example to get an idea on how to go about this. This example is based on the previous users message.

Actually memory card is not in Computer it is in one device which I connected to system. Device is Energy measurment Meter,I want to check memory card is inserted in that device or not

attach your memory card to computer
then find directory name and use it as path for vi that i send it image to you then you find out the size if the size is 0 it means that there is no card or card is full

The easiest way we found to do this with code running on RT targets was to attempt to write a file (e.g. a 1 byte binary file) to the device and see whether or not it was successful. I think there's also the 'get volume info' VI but I seem to remember something weird happening with it on RT targets...but it's been a long time since I tried it.

I am sorry but I don`t think you will be able to use LabVIEW File VIs to check for the presence of the memory card in an external device, if that device is not something LabVIEW can program. You can try exploring if your device supports a command set through Serial communication, TCP communication. If yes, then you could try sending those commands from LabVIEW. 

Best of luck with your application !
