Frequently asked question
There are no tools in ArcGIS Desktop that support or repair corrupted custom toolboxes.
The best solution is to recreate the desired toolbox. Refer to ArcMap: Creating a toolbox for more information.
Note: To prevent future data loss, if the event a toolbox is corrupted, make a copy of the original working toolbox that serves as a backup. Refer to ArcMap: Copying toolboxes for more information.
