Progress at List Folder function with many files in a folder

[Ben_Arts]

I use the List Folder function of LabVIEW and want to see the progress because it takes much time (20 sec) to load all the files in an array.

How can i do this?

see ListFolder example.jpg

Kind regards Ben Arts

List Folder Details

Note  Front panel controls might not update while the function lists files and folders found in the specified directory. The controls update when the function finishes listing the files and folders.

The above stuff comes from LabVIEW help.

I think this is not possible, unless anyone has someidea on how to do this (WIN32 API maybe?).

20 seconds?  Wow..  That is a long time.

Can you post your code?

More importanly, how many files are we talking about here? Is this on a network drive?

I showed a small picture that's all to do the job.

There are about 3000 files and the folder is a server. Probably that slows down the search. In this case i was looking for a progress for the List Folder to use that in a progress indicator for the user.

Have a nice day, Ben Arts

Well, that would certainly do it, especially since you said it's on a server, hence a network drive.

Unfortunately, there is no built-in mechanism for this. Perhaps you can organize the files in such a way that you can get a list of them in "chunks", based on some search pattern. Or perhaps you can organize them in folders so that you dynamically populate the subfolders when a user wants to see what's inside.

Aside: having 3000+ files in a folder is a poor way to orgranize files, especially on a server, as this leads to a massive amount of file I/O and network I/O burden on the server.
