(sorry if his is in the wrong section)
Im trying to save a text file with some commands as launch.bat but when save it as launch.bat i can see the .bat file where I saved for a few seconds but then it dissapears. I looked around on my computer and it wasnt anywhere!
Most likely your antivirus. Disable your AV and see if you are able to save it. You can also check your AV logs to see what its been up to. If it is in fact your AV, you can probably create an exclusion for the .bat you are trying to create.
