folder size

[unclebump]

Does anyone have a vi to show folder size in windows?? Inside windows explorer, when you right click on a folder and go to properties, it shows the size of the folder. I want to get that number inside labview.

There is a function available in LabVIEW for getting the folder or file size.
All Functions -> File I/O -> Advanced File Functions -> File/Directory Info

You can get more information on this function by using the context help (press CRTL-H and move the cursor over the functions).

I tried that one, but it returns the number of files in a directory, not the disk size. I found a dirsize.dll on the web, but I don't know how to implement it.

Might be easier to just get a list of all the files in the directory, get the size of each file and add them all up. You could do that with no dlls.

In the most general case, your folder might contain other folders with files, so it can get a bit complicated to get the total size this way. The OpenG toolkit has a "List directory Recursive" that might help you with this task. 🙂

OK, I'm so slow typing that I'll erase my mention of OpenG's recursive List directory, but will mention an alternative source on the LAVA forum:

Thanks a bunch. You guys are awesome. I'd give you all ten stars if I could. I followed the LAVA route and modified a vi made by Rolf. You can use this vi to sort your whole hard drive and find the largest files.

I modified the vi to use queues instead of the build array functions.

Hi Unclebump,

I have used both the VIs you have supplied. I observed that only the number of files list for the selected directory is indicated differnently. This number in Dan_Armstrong_List_Directory_Recursively_2.vi is showing one more than that indicated in Dan_Armstrong_List_Directory_Recursively_with_queue only.vi.

Kindly clarify me regarding this.

regards,

Ramkumar. D

Dan_Armstrong_List_Directory_Recursively_with_queue only.vi matches what you see when you right click on a folder and select properties inside windows explorer. I added a -1 inside the while loop.
