Creating a method to check for a mismatch between the last modified time and the file tree structure

Next, we will look at the pathCheck() method. After writing the hash signatures to the blockchain, the app renders the FolderBlock component. This component triggers the 5-second interval timer by calling the startTimer method. The startTimer method, in turn, calls the pathCheck method, every 5 seconds to verify whether there is a mismatch between the hash signature of the MTH (MTH) and FTH (FTH) written in the blockchain and the actual hash value of the MTH and FTH when calculated from the directory under observation. A mismatch indicates that some data in our directory has been tampered with.

Let's see how the pathCheck method achieves this: ...
