The Save tab

- The section Save Alarm has a pull-down menu which gives you options to either :

- Warn Me!
This option allows you to set an alarm that will remind you to save your project. You designate the interval between saves by entering the time in minutes in the box directly below the pull-down menu. At the end of the given time, a pop up alert will appear and will ask you to save your project:

The Save Alarm option

- Auto Save
This option automatically saves your file and also generates a backup file at the given interval starting from the moment you change your project. In case of some loss of information (due to crash, lost file, human error, corrupted file etc…), you can always have at least one recovery file available.
In addition, every time you manually save your file by keyboard command [CTRL + S] or by selecting File > Save from the Main Menu, TVPaint Animation will likewise generate a backup file.

The Auto Backup option

For even more safety, you can instruct TVPaint Animation to save a given number of successive backups. After that number of backups has been reached, TVPaint will start repeatedly saving over those backups in succession, starting with the oldest.

In the present case, "2" is written in the Auto Backup. This means each time you will save, there will be a shift between two backup files, plus a save on the main file (which is the one ending with the suffix “.tvpp”).

Backup files are saved at the same place than the original .tvpp project and are named as follow : file_name.tvpp.Year.Month.Day.Hour.Minute.Second.

The files created with the Auto Backup option Each time you will save, the oldest file will be modified, with a new date and hour.

To open a backup file, you just have to delete the part with numbers, in order to keep only file_name.tvpp.

Under Windows, an alert message will ask you if you want to convert your file as a .tvpp file. Accept, in order to open easily in TVPaint Animation. Under OSX, a popup window will ask if you wish to change the extension to .tvpp. Choose “Use .tvpp”
You can also drag and drop the file directly into TVPaint Animation.

- The last section TVPP compression allows you to compress the size of your TVPaint files (.tvpp) but keeps the same image quality.

Compressed files cannot be read by TVPaint Animation versions older than the 10.5.0 version.
