Restoring older versions

Hi. I am fairly new to audacity. I am an author and am using it to make an audio version of my book. Yesterday I must have done something wrong because one of my chapter files is now completely blank.
I have read previous posts online that sometimes these can be restored and other times they can’t. And I must admit I am confused and can’t seem to do anything that works.
I am using Windows 10.

Can someone please offer some guidance?

Thanks.

Actually I just got lucky realizing I had the file saved on Dropbox, so I could restore an older version that way.

Not just luck - this shows the power of a good backup strategy: :sunglasses:

Glad you managed to recover it.
