Synchronization
Item | Description |
|---|---|
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 JetBrains Rider 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 JetBrains Rider to a different application. |
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. |
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. |
