If you have a file open and make changes, then move the icon to another folder, or change the document name. This corrupts the file until the icon has been put back in the original place or renamed back to the original title. This causes lots of problems if you have multiple indesign files open and you are moving them around the computer as you work on different projects throughout the day. It is very easy to loose all of your work if you can’t remember the exact location of the original file or the exact name of the document when you first opened it. The recover never works. This has only been a problem since updating to 2018 indesign, please reinstate so we can have flexibly without the fear of loosing the work you have created. It was never a problem before the 2018 version.
