Environmental setup (setup of preservation)

	A backup file is created.	The file before one is saved as extension "BAK" at the same folder as a schematic file.
	A title file is embedded.	Data of a title is also put into a schematic file. If this file is read, a standard title file will be disregarded. It is used to save data with a title. Usually, it is made not to use it. (since a data file also becomes large)
	Automatic preservation	The method of automatic preservation of D2 CAD is set up in the number of times of updating, and delay time. If data change more than the number of times of updating is performed to each schematic file, a program will operate a delay time timer. Automatic preservation will be performed if there is no data change in the meantime. However, in the case of the following conditions, automatic preservation does not perform automatic preservation until conditions are canceled. 1) When having started the tool 2) When having chosen the item 3) When having inputted data If another schematic is edited, with an item chosen, automatic preservation of the file will not be carried out. Please change a schematic after canceling selection of an item, when editing ranging over a schematic.
	A file is updated.	Overwrite preservation of data is carried out by automatic preservation. If creation of a backup file is checked, the file before one will be carried out to BAK file.
	It saves at a specification folder.	It saves at the folder which specified the file saved by automatic preservation. When you specify a folder, please specify the folder which actually exists, with an "absolute path."
	Floppy disk prohibition	Automatic preservation is not carried out when the folder specified to be automatic preservation is a floppy disk.
