The question

I purchased a flash drive 2 years ago and was never reimbursed for it so I currently am still the owner. I personally programmed everything that is on that flash drive from me 100% from ground up. It is programs for setting on a paint line booth for automated paint guns. Each program is for different type parts, and different type paints and is programmed for all the setting for the paint guns application of the paint. I am quitting as they are not holding up their end of our agreement for my rehire after I previously had quit and the owner made offers and deals via text message that was confirmed multiple times and written out fully via text (which I still have) I have met all my ends of the deal, and they have not compensated accordingly to our deal and it is over a year later now and they aren’t going to. I am quitting for a better job, and I am wondering can I take my flash drive that I purchased and wrote all programs on alone? It is used daily by myself in the paint room.
