Solution

If we unzip the file, we can see there are many files in the folder. If we tried to find the flag, we will find there no named flag or picocTF in the folder. So we need to use grep to find the flag.

$ grep -r "picoCTF" .

big-zip-files/folder_pmbymkjcya/folder_cawigcwvgv/folder_ltdayfmktr/folder_fnpfclfyee/whzxrpivpqld.txt:information on the record will last a billion years. Genes and brains and books encode picoCTF{gr3p_15_m4g1c_ef8790dc}

we can see the flag is in big-zip-files/folder_pmbymkjcya/folder_cawigcwvgv/folder_ltdayfmktr/folder_fnpfclfyee/whzxrpivpqld.txt

Flag

picoCTF{gr3p_15_m4g1c_ef8790dc}
