# Directory Structure ## General The directory structure of VFLP is as the as for for VirtualFlow in general (as described [here](/documentation-vf1/principles-and-theory/directory-structure.md)). ## The `input-files` Folder What is specific for VFLP is that the `input-files` folder does not contain anything, except possibly the input ligand collection, which can also be stored at another location (as specifiable in the control file). The reason that the `input-files` folder does not need to contain anything is that the external programs which are used by VFLP do not need any input files except the ligands. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.virtual-flow.org/documentation-vf1/vflp/untitled-2/directory-structure.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
