# Supported input/output file format¶

Unsio supports different type of input files format. Known files format are automatically detected by unsio engine.

## List of files¶

List of files is made of an ascii file with one file file per line. Every file in the list must be a know file format supported by unsio.
Example of list of file :

cat list.input
snap_00001
snap_00002
snap_00003
snap_00004
snap_00005


Here, the file list.input can be used as input file for unsio.

## Sqlite3 database¶

A sqlite3 database is embedded to unsio which allows direct access to simulations stored in your storage area. Instead of giving full path name of a simulation, a user can give a simulation's name stored in sqlite3 database.
