After thinking a lot I decide to use DE cursors and continue my app.

In this software in intend to work with 2 data folders, alterning them by commands below

set path to data1

set path to data2

But the problem in "cursor" in DE I have a fixed full path

"c:/mysoftware/data1/table.dbf"

I found a solution

dataenviroment.curso1.controlsource = JUSTFILE ("c:/mysoftware/data1/table.dbf")

So I will have pure file

Now I have a doubt

I will this turn the application much slower since I will be using "set path to..." rather than full path ?
