Chris does this multi-file import work in SAS Viya with SAS Studio only. I have to upload files to SAS Viya cloud, using SAS Drive. So I have multiple text files myfile1.txt to myfile10.txt with same format, but to refer to them I'm using
filename ACH FILESRVC folderpath = '/Users/jwalker/My Folder/My Data/'; (also tried folderuri method) then I've tried multiple different infile statements. It works with one file but not with wildcard
this works
data dsn;
infile ACH("myfile1.txt") filename=filename;

Does not work:
data dsn;
infile ACH("*.*") filename=filename;

data dsn;
infile ACH(*.txt) filename=filename;

I also tried this:
filename ACH FILESRVC folderpath='/Users/jwalker/My Folder/My Data/' filename='*.txt';
DATA WORK.dsn;
INFILE ACH;
