Create multiple Files in a common Folder

Hello LabView enthusiasts,

 

I use multiple sensors to measure the pressure in a room. I have a task to store the measured data in a csv- file. The storage of the data and its timestamp is possible by my written program. However, I don't want to enter the file path every time I open my program (because the task is extended by 30 additional sensors and this would be quite time-consuming). For this reason I considered to create a File in a folder when starting the program, in order to save time and make the programm more efficient.
Is it possible to generate several different files with different data in a common folder? 
Unfortunately I did not find a successful solution. Does anyone have an idea or a starting point how to solve this problem?

 

In the apendix the vi and one image of the programm with multiple sensors.

 

Thanks for any help!

 

Cheers 

Jason

Personally, I like to put Date/Time stamps in my data file names.  So I can use Format Into String and Build Path functions to create the file path that I need.

That is usually a good idea.  And doing it in YY-MM-DD_HH:MM:SS format and the alphabetical sorting of the filenames will also coincide with chronological ordering.

Hey Gerd,

 

unfortunetaly I have Labview 2013 which doesn t support the "Create File with Incrementing Suffix" Vi. Can I program it by myself or is it even possible??

Yes, you can program it for yourself!

Spoiler
ListFolders to get the current list of files, find the latest file, create a new filename based on your rules, create a new file…

Just to close this loop...

I actually tend to use YYYY-MM-DD HH-MM-SS format.  Y2k (and Y3k) compliant!  It also makes it very obvious what is the year.  And, yes, the sorting is a bonus.  Here is a somewhat typical way I will create a log/report file path.
