Create a program that performs file processing activities. Your program will use the OS library in order to validate that a directory exists before creating a file in that directory. Your program will prompt the user for the directory they would like to save the file in as well as the name of the file. The program should then prompt the user for their name, address, and phone number. Your program will write this data to a comma separated line in a file and store the file in the directory specified by the user. Once the data has been written your program should read the file you just wrote to the file system and display the file contents to the user for validation purposes

If it is wireless, try resetting the computer/laptop's bluetooth or if its a mac, go to divice connection settings and restart that. or you could turn off the mouse and turn it back on. 

The main part about version control is that you have a repository, which hosts files. any changes done to those files are recorded and, as such, can be reverted back. it is kind of like google drive/google docs (except not as "real-time autosave"). usually these files involve code. version control can usually record changes to files and the lines of code themselves.version control is used by developers, mainly with coding. this may include websites, software, video games, etc. it is very useful in terms of practicality and collaboration.  reverting back a previous version of a file is very useful in the coding/programming world. suppose a programmer adds in something new to a file, a code snippet or two. then he changes his mind because he does not like the feature he coded in (it does not work, inefficient, with version control, he can easily revert back the changes he made.  version control also makes it easier to collaborate. oftentimes, you can use an online, remote  repository such as github or bitbucket. a team of people  can each  connect their computers  to this repository and be synchronised with the source code.recording your changes is also for teamwork  as it tells you who did what. changes can be monitored as well.  online repositories (like  github) may also contain  features to talk about issues with the code, and you can  reference them in the changes.version control also allows you to have different versions of the same thing. there are open source projects where anyone able can contribute to the project; such collaborators are able to create a new version (a new "branch") from the master branch. in this new branch derived from the main master branch, one adds their code and such.  in time, the original developer will look at this branch; they can add all or some of those changes to the main branch if they approve.
