Tip💡: how to create a new empty Chartarium recordset
At first run Chartarium generates an empty Chartarium csv recordset (the csv table which holds any record of the incoming and outcoming documental operations) named "chartarium.csv" into the Chartarium folder within Your device. For Mac OS, You may want to find the documents root folder of Chartarium within Finder (⇧⌘ G) ~/Library/Containers/it.envisys.chartarium/Data/Documents. For iOS, open the app Files. Select Your device (i.e. iPhone, iPad). Then browse through the folders of Your device until You find the home folder of Chartarium.
Don't forget, anyway, to select also a working folder which will be used by Chartarium to save Your job, that is, for example, all pdfs produced recording any incoming and outcoming operation.
If You want the autogenerated "chartarium.csv file" in some other else folder, You can simply move it through Files (iOS) or Finder (Mac OS). The name of the .csv file is not mandatory at all. Choose the one You prefer. The extension csv (and obviously the format of the table) is.
In any moment of the App lifecycle, You can generate a new empty csv recordset simply pressing the new file menu button on the top right of the Settings page. A new empty csv recordset will be created into the selected working folder. Don't forget to select it when done.
A new empty Chartarium recordset which conforms to the tech notes given elsewhere in this guide, can be generated forcing Chartarium to produce a new one, simply by picking any csv file which does not conform to the attended format.
Assuming that You have already selected a working folder, locate any - no matter which one - csv file through the file picker of the setting page. Once the App does not recognise the csv file You selected, will prompts You if intend to create a new empty csv table. Just press ok to proceed.
Chartarium will create, actually, a new empty csv register file table named "chartarium.csv" into the Working folder You selected, always in the setting page.
Don't forget to locate this file, once created.
