When you import a block the block spec is stored as a method under 'custom block specs' like this: 

forward: t1
    ^ ('motion' ('move %n steps' #- #forward: 10)) 

These can be deleted at any point in the browser but are useful to recover data. The block specs are stored into the class variable 'CustomBlockSpecs'
Selecting 'Delete All Custom Blocks' from the blocks menu will only replace 'CustomBlockSpecs' with this: 

#('obsolete' 'motion' #- 'control' #- 'looks' #- 'sensing' #- 'sound' #- 'operators' #- 'pen' #- 'variables' 'lists' 'obsolete' )

All block writing is stored in CommandBlockMorph!
