Several files can be opened and edited at once. Each open file is referred to as a buffer. The combo box above the text area selects the buffer to edit. Different emblems are displayed next to buffer names in the list, depending on the buffer's state; a red disk is shown for buffers with unsaved changes, a lock is shown for read-only buffers, and a spark is shown for new buffers which don't yet exist on disk.
"The autosave feature protects your work from computer crashes and such. Every 30 seconds, all buffers with unsaved changes are written out to their respective file names, enclosed in hash ("#") characters. For example, program.c will be autosaved to #program.c#."
JEdit will also generate backup files, which are terminated with a tilde (~) character. These have nothing to do with your task in this study. You can completely ignore them.
Saving a buffer using one of the commands in the previous section automatically deleted the autosave file, so they will only ever be visible in the unlikely event of a JEdit (or operating system) crash.
If an autosave file is found while a buffer is being loaded, jEdit will offer to recover the autosaved data.
The autosave feature can be configured in the Loading and Saving pane of tthe Utilities>Global Options dialog box;
Modify the application so that the users can explicitly disable the autosave feature. The modified version should meet the following requirements:
