|Reopen last project on startup||Select this checkbox to have IntelliJ IDEA re-open the last opened project on startup.|
|Confirm application exit||Select this checkbox to have a warning message displayed when you attempt to close IntelliJ IDEA.|
|Open project in a new window||Click this radio button to always open a new project in a new window.|
|Open project in the same window||Click this radio button to always close the current project, and reuse the same window.|
|Confirm window to open project in||Click this radio button to have IntelliJ IDEA ask you whether you want to open a new project in the same frame, or in a new one.|
|Synchronize files on frame or editor tab activation||If this checkbox is selected, all the files that were changed externally are reloaded from disk when you switch to IntelliJ IDEA from a different application, or when you you switch to their editor tab.|
|Save files on frame deactivation|| If this checkbox is selected, all modified files are auto saved when you switch from IntelliJ IDEA to a different application. |
Note that you cannot disable autosave completely by turning off this and the following option. See also, the Saving and Reverting Changes section.
|Save files automatically if application is idle for N seconds|| If this checkbox is selected, all modified files are auto saved at regular time internals. |
See also, the Saving and Reverting Changes section.
|Use "safe write" (save changes to a temporary file first)||If this checkbox is selected, a changed file is first saved in a temporary file. If the save operation succeeds, the file being saved is replaced with the saved file. (Technically, the original file is deleted and the temporary file is renamed.) |
Also, the ownership of such file changes.
If this checkbox is not selected, the ownership of a file does not change, but all the advantages of safe write will be lost.
