>How Can speed up the exe file.

Here are some aspects you might want to consider:

The computer should be fast.

The computer should have enough RAM. If it has too little, the computer will start using virtual memory. This is slow.

The network should be fast, and optimized. For example, a large network which uses only hubs will be very slow.

Your program should be optimized. Ask again, if you have difficulties optimizing a certain part. For example, when you select data with SQL - SELECT, there can sometimes be a great difference in speed, between an optimized command, and a command that is not optimized.

Know the VFP commands well. Sometimes, a few commands - or even a single command - can substitute a complicated loop. If you use the simpler commands, you have less programming work - and quite often, your program will be faster. An example is, once again, the SELECT - SQL command: a single SELECT - SQL command can often substitute scores of other commands.

Know when to use indexes in your tables, for fast data access.

If you need to access a small subset of a large table, use parameterized views.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
