# Workspaces

Sometimes it is necessary (and practical) to record a dataset in multiple files. COSEDA has a feature called workspace to handle this case. There is no need to merge your files into a single file. After you imported all your files you should have a project folder, containing the `.h5` file, an `.ini` file alongside some other stuff. You can add and remove as many files as you want. The workspace can be saved as a `.cosedawsp` file. This file is nothing more than a little plain text files, containing some GUI settings and the paths of you `.ini` files. If you open it in a text editor, it looks like this:
```
# Colormap=inferno
# LogNormalize=0
# ShowBeamCenter=0
# ShowPeaks=0
# Gamma=1.0
# Brightness=1.0
# Contrast=1.0
/Volumes/DATC/UOX_small/20240302_1056_run_2025-09-07_17-13-54/20240302_1056_run_2025-09-07_17-13-54.ini

```
If you reopen COSEDA, it will try to recover your latest used workspace automatically. You can also use the _Open Workspace_ button to choose your workspace in a file dialog.

> **Note:** Please make sure that all the files you add to a workspace stem from the same experiment (i.e. were collected under similar conditions, e.g, camera length)
