I am a solo developer tracking my project changes through Git Gui. Recently, in one of my projects, I incorporated an excel macro .xlsm file. This created a temporary file of the same name with "~$" prepended to it, which gets stuck in Unstaged Changes. I can continue my commits by staging necessary files one-at-a-time by hand, but this is slow and annoying. When I click on the "~$..." file I get a pop-up error saying Error loading file: couldn't open 'path/~$filename.xlsm': permission denied. I can't figure out how to get Git Gui to forget about this, or deal with it myself in some other way. Did some searching. Thanks!
Add to .gitignore. If .gitignore does not exist, create in the root directory of your project and add
~$filename.xlsm
