Hi, I need some help. I have a sd card and I have ten text folders on it and a phone number in each. I need the program to gradually open it and store the numbers in different variables. Did anyone solve this? Thank you

What have you tried ?
Do the folders and filenames have any structure that would lend itself to being programmed ?
Do you know how to open a file and read from it ?
Please do not send me PMs asking for help.  Post in the forum then everyone will benefit from seeing the questions and answers.

Unsure why folders must be used as storing in a string or data array with separators would be my preferred method

eg.

123456,789012,234678, etc.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
