6. File Backup and Versioning
Some EDA tools make backup and versioning easier than other EDA tools. But it is very disappointing to lose all of your work due to a power failure or runtime error in your EDA software. You should save your work frequently, and if possible, automatically. Setup your software's auto-backup feature now, and you'll not be tempted to kick your computer later.
Also, decide how you would like to keep track of revision and file-naming. Unless you are working under the guidelines of your company, this will all be personal preference.
I have personally gotten into the habit of appending the date and sometimes time in year-month-day-hour-minute order to keep track of my files: examplefile_202005081018.txt is 05/08/2020 at 10:18 a.m. This keeps them arranged chronologically in my file directory and makes it easy to write a script to purge a directory of excess backups -- just sort alphabetically (usually the default option) and if there are more than 5 backups, delete all but the last 5.
