 Delete file service for Home Assistant. For example delete snapshots.
 
 ## WARNINGS
-- **All files and file extensions are case sensitive (e.g. `JPG` in not same as `jpg` or `jpeg`).**
+- **All files are case sensitive.**
 - **Custom component is run from Home Assistant and has access from same python runtime environment. It means no access outside of Home Assistant visibility (for example Hassio paths or folders).**
 - **Home Assistant runs custom components not as `root` and thus permissions towards files and folders must be checked manually as component cannot change to the user with higher privilidges.**
 - **Integration should delete data only within specified parameters so removal of unwanted files is users responsibility (correct specification of names).**
