First we need to make backup of the contents flash cards.

Forbidden to use flash cards capacity more than 2GB, because software windows CE 5 could be damaged.

Please do not use original Chinese Micro SD card readers! Please buy quality card reader. Flash card could be damaged!

Usually there are 2 folders on a flash card:

And inside of the GAG folder there are:

We need to choose VEHICLES folder. In VEHICLES there are many car model folders:

And inside of each car models folder few program versions, for example FIAT:

In FIAT folder 16 program versions, one oldest is 23.50 and newest is 34.00. You need to choose only files which you need, capacity of flash card is 2 Gb only, no reason to use folders like CHANGHE, GUCHAIZY if you will not use it NEVER! Capacity of all files is 14,0 Gb.

Some versions let to list below or upper page, but not all versions let to do it.

It is important to use ENGLISH language, because some version works only in English. For example BMW 47.40 version works only in ENG, but 47.50 version works only in RUSSIAN language, it depends of which market your Launch Diagun – for Russia / EU / America / Asia etc.
