Example.png

I have data stored in files as seen in the screenshot attached. I want to create a script that will automatically access each file and load it into the workspace with the same name as the filename. I'll be using fopen() and fread() to access and read in each individual file. There are other file types in the folder that I do not want to import (the png and .m files). Any help would be appreciated.

I strongly recommend that you change your OS settings to show file extensions:

Otherwise working with files is confusing and more complex.

Thank you so much! Yes I was wondering how to figure out what the file extensions were for these. Was pretty disappointed when properties didn’t tell me.

See FAQ: How to process a sequence of files

"with the same name as the filename" - This is a bad idea. Prefer to use either the same name or an array. Creating variables dynamically with names determined at runtime are a shot in your knee.
