tool: D275: The new file descriptor is %d 


tool: D381: Now we close and then remove File2 from the disk

tool: D89: %d Error in removal

tool: D71: 
Now we do ls() :

tool: D364: We will now write what we have read into big_file_number3.txt

tool: D101: And now, we ls() : 

tool: D400: Now we reset the filesystem

tool: D133: FileSystem Reset

tool: D121: We want to reload the disk
