Using .bak files

Specific actions cause Allplan to make backup copies (files ending in .bak) of the drawing file/layout in question. The .bak files and the original drawing files/layouts are stored in the same folder, i.e. the project folder. You can specify whether .bak files are created or not in the Options, Desktop environment page.

If you have inadvertently carried out a function, you can use the .bak file to restore the original data of a drawing file/layout. All you need to do is rename the drawing file/layout in Windows Explorer.

The following actions cause Allplan to create .bak files

• When you select the Copy, Move Elements between Documents tool.
• When you delete drawing files and layouts using Delete Document....
• When you delete the contents of drawing files and layouts in the Open on a project-specific basis: drawing files from fileset/building structure or layouts dialog box.
• Before you import data to drawing files using  Import
• Before you import data using Add drawing files and layouts with resources to project.

Note: Please note that these backup copies may increase the volume of data involved in backing up projects. You should therefore delete unnecessary .bak files before you start the backup. You can use the Services application to delete .bak files. Open the Utilities menu and click Delete temporary files.
