The problem FileMaster solves

Declutters all your files on Telegram, by allowing them to be organized into folders.

Challenges we ran into

We were making a terrible and stupid mistake of not making a copy of the directory path in the previous directory path variable and instead were using a reference, so the previous path kept changing with the newer path as the user traversed the file tree deeper . Then we made a deep copy :) and the previous path actaully pointed to the previous path.
