You will need to use the "lib" syntax to save the qvd. So in your case something like:
STORE Test into [lib://R&D/Test1.qvd];
If you want to use path names eg d:\test\ then you will need to enable "Legacy Mode".
See the help page here if you wish to do this.
The suggestion that Tim has provided is the correct step with the default settings in Qlik Sense.
You must use the LIB syntax instead of the drive letter.
You must have a folder connection created with a name that you will also reference in the LIB statement:
Here is the correct syntax that should work for you - with a sample table:
if(RecNo()>=65 and RecNo()<=90,RecNo()-64) as Num,
Chr(RecNo()) as AsciiAlpha,
RecNo() as AsciiNum
Where (RecNo()>=32 and RecNo()<=126) or RecNo()>=160 ;
STORE ASCII into [lib://myFolder/Test1.qvd];
Note: If you want to use the drive letter the way you would using QlikView- you must Disable Standard Mode (Qlik Sense Desktop)
You can read up on that here:
Hope this helps.
