LibreOffice exports all settings
All the settings of LibreOffice, all in the LibreOffice folder.
C:\Users\a←When installing the operating system, the name entered.\AppData←File Manager ~ “Hidden project” to open, the AppData folder will be displayed.\Roaming\LibreOffice
Back up the LibreOffice folder, when reinstalling, put the LibreOffice folder in its original place.
Note:
1. If the installation is preview edition, because the name of preview edition is LibreOfficeDev, so the LibreOfficeDev folder will be displayed.
2. Formal edition can be installed together with preview edition, if both formal edition and preview edition are installed, LibreOffice folder and LibreOfficeDev folder will be displayed.
3. To clear all settings, just delete the LibreOffice folder, then open the program, a new LibreOffice folder will be created.

Backup file, when reinstalling, put the file in the original place.
Note:
1. Because of the toolbar that I made myself, default file name, will automatically use Numbering, so to open the file, can know the name of the toolbar.
2. The front file name “custom_toolbar_” cannot be changed, change will cause error, behind’s file name can be changed.
For example: custom_toolbar_c01611ed.xml→custom_toolbar_AAA.xml.
3. Do well of toolbar, can be copied to other places to use.
For example: In the “writer” Do well of toolbar, can be copied to “calc” places to use.
