A simple open source file format in which to save a variety of different files from different sources has been introduced with version 0.16. It simplifies data storage (single file instead of a folder of images) and loading (for instance, in the case of Swiss SPAD 2 data, pre-processing of raw data is not necessary anymore, once saved as an AlliGator HDF5 file). In addition, the format includes a lot of metadata which helps with traceability and reproducibility.
Details about the format itself can be found in the AlliGator HDF5 File Format page of this manual.
To load an AlliGator HDF5 file, simply use File>>Load>>Dataset>>Open HDF5 FLI Dataset (Ctrl+O).
To save the loaded dataset (irrespective of its origin), use File>>Save>>Dataset>>Save as HDF5 FLI Dataset (Ctrl+Shift+S).
