How to undo a delete?

How do I undo an accidental delete when using the editor for a .m file, or alternatively retrieve the .m file from before the accidental delete?

It depends on what you deleted. If a bit of code in the .m file you’re editing, in the very top Editor taskbar near the right end, there are two curved arrows. Clicking on the one that points to the left will undelete inadvertently deleted text.

For .m files, depending on the preferences you have set (particularly autosave), you might find the complete or earlier version of it with the same prefix and an .asv (instead of .m) extension. Otherwise for a deleted .m file, on Windows machines look in the Recycle Bin. (No guarantees — I’ve not done that so I have no personal experience — but that is where I’d look.)

If you accidentally deleted a file or folder (such as if you right click a folder and you meant to click "new->script" and instead you hit "delete" like I just did), And if you're using windows, you can navigate to the folder in windows explorer and ctrl+z.

i.e. I just deleted the folder "src/myProject/test/files" so I navigated to "src/myProjects/test" in windows explorer and hit undo (ctrl+z) and the folder repopulated!

Look for a file with the same name but a .asv extension. This is the prior version - your autosaved backup file.
