+## File Base ACS
+[ACS Codes](../configuration/acs.md) may be used to control access to File Base areas by specifying an `acs` string in a file area's definition. If no `acs` is supplied in a file area definition, the following defaults apply to an area:
+* `read` : `GM[users]`: List/view the area and it's contents.
+* `write` : `GM[sysops]`: Upload.
+* `download` : `GM[users]`: Download.
+
+To override read and/or write ACS, supply a valid `acs` member.
+
+## Example File Area Config with ACS
+
+```hjson
+areas: {
+	retro_pc: {
+		name: Retro PC
+		desc: Oldschool PC/DOS
+		storageTags: [ "retro_pc", "retro_pc_bbs" ]
+		acs: {
+			//	only users of the "l33t" group or those who have
+			//	uploaded 10+ files can download from here...
+			download: GM[l33t]|UP10
+		}
+	}
+}
+```
