Pro-grammatically create a path when using Write Waveforms to a File.vi

[Clint1000]

How do you create a unique file name when using  Write Waveforms to a file.vi that is in a loop ?  I have that VI in a for next loop and want my file name to be unique to each iteration of the loop.  For example, the 1st iteration of the file might be c:\testing\filename1.dat  then next c:\testing\filename2.dat ..then c:\testing\filename3.dat ..etc..  How do you concatenate the file name w the loop iteration to come up w a filename that is unique w each loop?

Use Format Into String to combine the base filename with the iteration number to create a new file name.  So your format string could be filename%d.dat

Then use Build Path to combine the file name with your base path for the directory structure.

Perfect..thank-you.

A very tiny addition:

You might want to consider a number format specifier like "%03d".  This would pad with 0's and make all numbers 3 digits wide, which is handy when you want to sort by filename when navigating into the folder.

Or maybe just use the built-in function that AQ wrote, located in the Advanced File Function Palette:
