Hello to everyone.
First of all, excuse my bad english, i will try to be as clear as possible.
so my problem is: i have deleted a file called unsigned.txn from my computer, and i have discovered it is related to electrum.
i have a desktop portable electrum wallet 2.9.3.
i hope it was not a mandatory file or something, so have i done something wrong deleting this file ?
When you create a transaction, you can either send it immediately or save it as a file.
When you send it as a file, it can either be signed (ready to be sent/broadcast without any passwords or anything else required) or unsigned. It generates a file called signed.txn or unsigned.txn, accordingly.
So, you must have created that file at some time by clicking "Save" when sending some coins. It doesn't matter if you deleted it, especially because the transaction wasn't signed.
