Hi Alexandre, welcome aboard !This kind of question should ideally be asked in the d.learn forum, not here. Anyway, to create directories, you can use std.file mkdir and mkdirRecurse function. To get file information, there is the getAttributes function in the same module.
Note that for builing path names, you can use std.path buildPath function, which is portable between Windows and UNIX :
string DestDir = buildPath(DirReceb ~ MesesDoAno[mes - 1], strdt, fi.Name);
Cheers, Olivier
