This is a voice from Japan participated in Ver 4 Beta testing.  Due to many inputs from the participants, it is understandable that eBoostr team keeps science as to release of Ver 4.  The most of testers takes it that the eBoostr developer team is now dedicated in finalizing the best end-product.  With that, the majority of testers is believed to be patient  with and positive toward the release of Ver 4 .  For the time being, some testers like me are still doing test of RC Build 553.  Here, for sharing the information among the testers, I would like  to provide some info.  I put the following files and folders in the exclusion list, then I drastically could save the capacity of USB Flash memory thumb drive.  Simultaneously, the performance of the eBoostr is being increased.  Nothing but just FYI.   [Bunji94 from Japan]
