question about auducity

i downloaded auducity to help my grandpa save some conversations of his off a recorder but every time i saved a "project" i got a bunch of extra data in a folder called "file name" data, my question is do i need this stuff for the other recordings to work? its kind of a rush sence he need to know if he can delete the iles i recorded from his recorder. he needs it by monday so its a bit of a rush job

tyvm in advance for all the help

 

i found out you do still need them the program runs a file by keeping individual snips of the file and then one file to open the snips almost like a short cut
