How can i get rid of Backup Files?

Question

Hi,
whe using "Write To Measurement File" and  "Read From Measurement File" i read and save to the same file (i.e. "example.lmv"). When i run the program and the signal is saved in this file, the information is saved in the file but at the same time it creates a "backup" file; I noticed that this is caused when i use "Read From measurement file". Is there any way that i can run the program, without creating this backup files? I run the program many times a day and i dont want to fill my computer with these files every time i run it.
Thank you for your help,
Guillermo 
P.S: I attached an example VI and the file where the signal is saved.

Answer 1

Thanks for your help again.  The VI that i sent you was a mere example of the true program that I am working on. This program controls a motor and rotates it counter clockwise and clockwise. I can only rotate the motor a maximum of 360 degrees so i set up the program to give me an error whenever I rotate the motor 0 degrees or less and 360 degrees or greater. To do this, I write the mount of degrees desired on a file ("Write to Measurement File") and the next time i rotate the motor I use the "Read from Measurement File" to read the previous amount of degrees that i wrote and adds it to the new one and saves it again on the same file. When this number of degrees reaches 360 degrees, it gives me the a message that i have to change the direction of the motor. The issue that i want to fix is that every time i write to the file it also creates a backup file and i want to get rid of it so i dont have a new file created every time i run the program. I noticed that whenever i use a program that just writes on a file using "Write to Measurement FIle" it writes on that file, only, and  does not create a backup file. Whenever i use "Read to measuremnet file" to then write the signal in "Write to Measurement File" the backup file is created; so i came to the conclusion that is the "Read to Measurement File" that is creating this backup. Is there any other way to call a file without creating this backup file? 
Here i will add the three VI's so you can see what i mean. I will add the full program, and the two examples that i explained above.
Thank you,
Guillermo Naranjo.
