You are given the title "I enumerated" and the file "II - encrypted.7z". Read the "I" as the step number and use "enumerated" as the zip password.
That opens the zip and gives you four text files as well as one html file. That file contains an overview of the puzzle steps.
You start by solving the three files "III - counted.txt", "III - 01â‚‚.txt" and "III - drew.txt" individually, then use each answer together with "IV.txt" to get another solution. As a hint you are given the theme for both steps (counting, binary or drawing).
Count the letters in each row. The most frequent letter of the lines are "M", "O", "R", "S" and "R" respectively.
The five separate parts of each line are dots (2 letters) and dashes (5+ letters) and give you the numbers 7, 2, 7, 8, 3 in morse.
Use those numbers as letter indices for the lines to get the solution TIGER.
Convert the base64 to binary, line by line.

Read the solution in the resulting image: ACCENT.
Read the lowercase letters: "take only upppercase letter". Typo not intended…

Take the uppercase letters as drawing instructions (north=up, northwest=diagonal etc.). This spells out the solution MOLE.
Take the solution TIGER and count the number of occurrences of each letter.
{'T': 1, 'I': 2, 'G': 15, 'E': 18, 'R': 20}
A1Z26: 1 2 15 18 20 -> ABORT.
Take only the 0's and 1's from IV.txt.

XOR that with the ascii values of ACCENT to get "NUTS".
Hightlight the occurrences of each letter of MOLE in IV.txt.

The letters draw the solution RIPE.
Anagram the three solutions encircled in the image, ABORT NUTS RIPE, together to get PERTURBATIONS. Then anagram the first three solutions from earlier to get ELECTROMAGNETIC. The final answer is ELECTROMAGNETIC PERTURBATIONS.
