I have been working on the flow for months for my sch project and now its no where to be found.I'm like 80% done. Didn't open it for at least 2 months. This happen before perviously as well and i redo it.
Any ways to retrieve it ???!!!?
what operating system is node-red running on?
are you using docker?
can you post the startup log - it will tell us where your files are stored. In particular
4 May 12:06:27 - [info] User directory : /pi/.node-red
Once you find your user directory you should be able to find a) some flows_... files and also maybe some hidden files named .flows_... (starting with a . )
The .flows_ files are one level previous version and the flows_ files are the latest.
Sometimes what happens is that your machine may pick up a new hostname (unusual but does happen particularly with Macs on Wifi and/or DHCP on different networks eg home then school. The flows_xxx file the xxx will change depending on the hostname - so you can just start Node-RED like
node-red flows_myfilejson - Ie fully specify the flow file name on startup.
