Hi all, I am trying to store some data in compact flash memory card. Directory creation, File creation and writing data into file is working fine. But i want to know the available free memory of the card. I tried to subtract file size from total size of the card but it is not working.
Adding file sizes requires that you round upwards to full cluster sizes. And the same thing is needed for directories.
Best is always if there is a function to report the number of free blocks on the device. I don't have the kit with the FS, so I don't have access to the Keil manuals.
Thanks for your response. can i have some clear explanation
Clear explanation of what?
I am getting free space available if entered into any directory. When I given command being in root directory I am unable to access the size of file present in other directories. And I am getting the size of all files present in root directory. Finally I am unable to get total utilized space.
