If an open buffer is modified on disk by another application, a warning dialog box is displayed, offering to either continue editing and lose changes made by the other application, or to reload the buffer from disk and lose any unsaved changes made in jEdit. This warning dialog box can be disabled in the General pane of the Utilities>Global Options dialog box; see the section called “The Global Options Dialog Box”.

File>Reload can be used to reload the current buffer from disk at any other time; a confirmation dialog box will be displayed first if the buffer has unsaved changes.

File>Reload All discards unsaved changes in all open buffers and reload them from disk, asking for confirmation first.
