I have this SharePoint 2007 document library which has several levels of folders and files. Some folders in the middle of the hierarchy do not inherit permissions from their parents and have their unique permissions defined. It is a huge library and there are many folders like this.

I am currently changing the permission model of my library and I want to reset all those unique permissions and have all of them inherit permissions from the library root. (Something like "Replace child object permissions" checkbox available in windows files system security window)

If this is not possible, seeing a list of folders that have their unique permissions defined would also do.
