The problem is before IF

I runned the test below

********************************************
STORE mydir1 TO MyOldPath && my old dir
STORE "C:\data" TO MyNewPath && my new dir

lnOldTables = adir(laOldTables, MyOldPath + "*.dbf")
lnNewTables = adir(laNewTables, MyNewPath + "*.dbf")

= MESSAGEBOX (STR(lnOldTables))
* returns 17

= MESSAGEBOX (STR(lnNewTables))
* returns 0 though there are 10.dbf files on the its folder
