When using Audacity to record and edit various projects, your data may seem lost when a crash occurs with the program. However, restoring files that are used with Audacity sometimes is possible by checking the Temp folder, which stores your project files. Another option is to use the Audacity Recovery Utility to restore any lost project files, as the result of a crash. However, you will need to first enable hidden files and folder on your system.
