Solved!

Hi, 

 

I need to look at several files of data. How can I loop through all the files in a directory in order to get the data from those files? 

 

 

Thanks very much

Build an array of the file names in the folder you are interested in, using the Advanced File Functions "List Folder" under File I/O, then index through the file names (a while loop possibly) where each file name will be used to perform whatever function(s) you are trying to perform.

An autoindexed FOR loop would be the way to go.  As already stated, use the List Folder function to get a list of the files in the folder.

You can use either

a. List Folder Function OR

b. Recursive File List VI

 

Later is useful if you have nested folders containing data files, so you can input the top level directory and this VI will output all files in that folder or any sub-fiolder.
