Any hints? I tried everything that was hinted on the comments above!
my hint: ‘ls -R’
does tree command help?

Thnx man, solved 
I cannot for the life of me decode the flag correctly. I understand the ls -R hint but honestly used the output of unzip instead. My issue is a certain value gets mangled causing the flag to have unprintable text. Did I miss something? Please PM or answer here if you are willing to help.
i think i got the right string out of the files but i can’t figure out how to decode it. it doesn’t seem to be any valid hash type. could someone please point me in the right direction?
got it, the online decoder i was using just couldn’t decode it, 2 others worked fine.

Some respect maybe?
Sure 
this one is very easy.
pattern is obvious
I extracted files. So we need to keep the file names in the flag or directory names? Do we need sort the names? Thanks
Well just look at the structure… Hint should be there I guess
Mind blowing challenge just completed it if any one need help feel free to pm.
nice and easy challenge, but you can do this one only on linux

It is important to have both upper case and lower case subdirectories present in the filesystem to be able to come up with the solution.
When I have opened the zip file under Windows, I was seeing something like the following.
E.g.:
U:
9
20
28When I decompressed the zip under Linux, things looked different.
E.g.:
u:
20
28U:
9As you can see, the files are organised in a different way. I hope this helps.
Thank you @ShingoTamai
If you can see part of the flag or what looks like a corrupted flag, try using a different tool/OS to extract the file.
On my mac, Archive over wrote directories, while Unarchiever created directories with numbers to differentiate between directories with same name but different capitalization.

… tired … there is a relationship between the directory name and the content
I try to concatenate the name with contents like
B23 etc. Is this the right way?
some hint some hint … exhausted

Holy ******* ■■■■.
Had exectly the same problem. Unzipped with windows and got a wrong flag. Searched for any mistake for hours. Never Again - lesson learned.
A fun challenge this. @ShingoTamai 's comment is vital when first starting. I would suggest using Linux for simplicity. It’s actually possible to get the flag with one line of piped commands. PM if you needs hints.
