+# `fileexists` Function
+
+`fileexists` determines whether a file exists at a given path.
+
+```hcl
+fileexists(path)
+```
+
+Functions are evaluated during configuration parsing rather than at apply time,
+so this function can only be used with files that are already present on disk
+before Terraform takes any actions.
+
+This function works only with regular files. If used with a directory, FIFO,
+or other special mode, it will return an error.
+
+## Examples
+
+```
+> fileexists("${path.module}/hello.txt")
+true
+```
+
+```hcl
+fileexists("custom-section.sh") ? file("custom-section.sh") : local.default_content
+```
