Helen, you keep saying 'that is how Archive works', but the app is called Sync. I know I'm not trying to 'archive' anything, I'm trying to TWO WAY SYNC between two disparate devices, a PC directory and an Android externalSD card. Many of use who have been with BT Sync from its inception on Android embraced the app as a fundamental 2 way sync app. BTSync capitalized on this feature because it was missing in Dropbox and others. The whole selling point of a two way sync is proper work flow whereby mobile files may be edited, altered, and deleted on PC and this carries through back to mobile device. I understand now the app has been fundamentally rebranded in light of a new monetization effort (circa 2.0), but the feature defeats the purpose of many original usages of this app, which many here attest. If the 'feature' can't be switched off (manually or otherwise), there should a setting to allow delete of archive upon successful sync. But I digress... I'll never update to the terrible new version. I'll have to use another app to continually purge this idiotic 3rd file 'backup' space. Just hard to believe we can't turn it off in a .nomedia kind of way.
