 ModCleaner is a small desktop utility for cleaning a game folder with a simple keep-list.

+It works by comparing the current contents of a game directory against the active keeplist file. By default that file is `#keeplist.txt`. If a keeplist prefix is active, the file becomes `#<prefix>-keeplist.txt`. Anything not covered by the active keeplist is treated as removable. This makes it useful for returning a heavily modded game install to a known-good state without manually sorting through every file.

+
+ModCleaner supports an optional in-memory keeplist prefix system.
+
+- default keeplist: `#keeplist.txt`
+- prefixed keeplist: `#<prefix>-keeplist.txt`
+
+The prefix UI is intentionally hidden behind `Ctrl+K`. This is to avoid confusion for users who just want a single keeplist file.
+If you want to use prefixes, press `Ctrl+K` and enter a prefix to switch to a different keeplist file. You can have as many keeplist files as you want, but only one is active at a time.
+
+> [!NOTE]
+> Keeplist prefixes are an advanced feature. They do not add extra scanning behavior; they only change which keeplist filename `Generate`, `Scan`, and `Clean` use.
+
+Rules:
+
+- prefixes are stored in memory only
+- an empty prefix returns to `#keeplist.txt`
+- valid prefixes may contain only letters, numbers, `_`, and `-`
+- invalid prefixes are rejected and do not change the active keeplist
+
