aliennation

Hey, yall. I need help with garbro, specifically creating archives within it. Right now i have extracted all the scenario file from scenario.xp3 and now want to repack it with my tl to test how it looks. However, when i go to create archive and select all the .ks files, it says it cannot access the file because it is being used by another process. It even does this with files i have not even touched. The specific game i am doing this for is Natsuzora Kanata https://vndb.org/v701/chars#chars Hope yall can help.
