<div style="background-color: #E3FBE5;">'''Important information''':
The gBak is a test utility created to achieve certain goals, e.g. to transform the files from any version prior to MultiCharts 8.0 Beta 1 to be used in any higher versions than MultiCharts 8.0 (example: from MC 7.4; MC 7.2; MC 7.0; MC 6.2 and earlier to MC 8.0). After the .bat file is used, the database files can be used both in MC 32-bit and in MC 64-bit.
Database files from any 32-bit version (since MultiCharts 8.0 Beta 1) can be used in any 64-bit version (since MultiCharts 8.0 Beta 1) and vice versa without any transformation (applicable only to MultiCharts of the same revision ex. 9.1 x32 & 9.1 x64). '''In some cases utility can also help to reduce the size of the database, but as it is not its main purpose, the results cannot be guaranteed.''' [[Category:FAQHelp]]
