I do not know what I’ve changed recently, but my csv files does not more have the extension set in the Save As Dialog.
The file type definition is:
[code]CSV
Display Name: Comma Delimited Value (CSV)
Description:
UTI Identifier: public.comma-separated-values-text
Conforms To:
Extensions: .csv
Mime Types:
OS Types: ???
UTI Type: Imported[/code]
I provided an Icon for this file type.
Nota: AppleScript (return properties of MyFile) returns
file type:"TEXT",
creator type:"ttxt",
Xojo 2016r4.1
El Capitan .6
[Edit] I forgot: I use TextOutputStream to save the data into a csv file.
