[CVI 2013] How can I get a folder size ?

[HoussamAz]

Hello,

How can I get a folder size to display on CVI ?  (This folder contain many sub-folder and many files).

In my application, The user select a folder, then he should see the size of the selected folder in the interface.

Thanks in advance,

Houssam

Unorthodox, dirty and nasty answer: let the system do the work for you!

Launch a "dir . /s >> dir.txt" command, open the output file dir.txt and in the last-but-one line you'll find the figure you want!

On my system the command took <2sec to create a 67500+ lines file on a heavily nested subtree, with this output:

 Il volume nell'unit… C è Acer
 Numero di serie del volume: ******

I'm not aware of a single function that does what you want and if I'm to loose my time on a recursive function that scans the path an sums up files and.... I go the nasty way!

Yes I undrestund, thank you.

Bu how to execute the Cmd instruction, and how can I copy the result to my CVI code ? Do you have an example please ? 

Thanks in advance,

You can issue the command using LaunchExecutable () or System () , then parse the output file with File I/O functions.

A little correction: I suggest to use the command "dir . /s > dir.txt" that regenerates the output file each time, while ">>" command appends data to existing content if the file already exists.
