-Recommendations for the file name in the quantms project.
+The files within a project are in the current version <<version>> optional. Files within a project should be listed in the quantms_files, for every file the following information is necessary:
+
+- file_name: The name of the file or folder.
+- is_folder: A boolean value that indicates if the file is a folder or not.
+- partition_fields: The fields that are used to partition the data in the file. This is used to optimize the data retrieval and filtering of the data. This field is optional.
+
+NOTE: Parquet files can be storage as folders when the data is partitioned by some fields. For example, a parquet file that is partitioned by the `sample_accession` field will be stored as a folder with the name of the field and the value of the field.
