What are the rules for naming a file?

The default file name is determined by the name of the unit that the file contains. The name is formed by taking the full expanded name of the unit and replacing the separating dots with hyphens and using lowercase for all letters. An exception arises if the file name generated by the above rules starts with one of the characters `a', `g', `i', or `s', and the second character is a minus. In this case, the character tilde is used in place of the minus. The reason for this special rule is to avoid clashes with the standard names for child units of the packages System, Ada, Interfaces, and GNAT, which use the prefixes `s-', `a-', `i-', and `g-', respectively. The file extension is .ads for a spec and .adb for a body. The following list shows some examples of these rules.main.adsMain (spec) main.adbMain (body) arith_functions.adsArith_Functions (package spec) arith_functions.adbArith_Functions (package body) func-spec.adsFunc.Spec (child package spec) func-spec.adbFunc.Spec (child package body) main-sub.adbSub (subunit of Main) a~bad.adbA.Bad (child package body) Following these rules can result in excessively long file names if corresponding unit names are long (for example, if child units or subunits are heavily nested). An option is available to shorten such long file names (called file name "krunching"). This may be particularly useful when programs being developed with GNAT are to be used on operating systems with limited file name lengths. See Using gnatkr.

Yes. If the file ends with .zip, it is a ZIP Archive file. There is a way to change the extension, however, using an extension changer found on the internet. The filename extension (characters to the right of the dot in the file name) identifies the type of file (unless this extension is renamed by a computer user) in most cases. The type of file will identify what can use or open the file, but not necessarily what created the file.
