 ## Saving files for restarts or adjoint runs
 
-The SU2 binary restart format has the extension `.dat`, but it is also possible to write out restart files in a simple ASCII file format with extension `.csv`. Have a look at the [Output section](/docs_v7/Custom-Output/) to learn how to change output file formats.

 A restart file with the name given by the keyword `RESTART_FILENAME` is then saved at the end of the simulation, or after every number of iterations given by the keyword `OUTPUT_WRT_FREQ`. For instance,
 
 `RESTART_FILENAME= restart_flow` \
 `OUTPUT_WRT_FREQ= 100`
 
-will write the file restart_flow.dat every 100 iterations when then the total number of iterations is larger than 100, or only once at the end of the simulation when the total number of iterations is smaller than 100. Note that the file extension (the suffix) is automatic and can be left out.

 If you would like to keep copies of previously saved restart files, this is possible by setting
 
 `WRT_RESTART_OVERWRITE= NO`
 
-This option is available only for steady simulations. In unsteady simulations, the number of timesteps is appended to the filename automatically. Additional to the regular restart file, a restart file with the current iteration appended to the filename will be written every `OUTPUT_WRT_FREQ` iterations.
