The Help Center documents a one-way USB transfer from Android to Windows. Use it when the two devices cannot share a local WiFi network.
The older guide names Downloads/VoicePad/mobile_export.json. Use the actual location shown by your version if it differs.
This workflow moves notes from Android to Windows. It does not send Windows notes back to Android, and it is not an iOS or macOS USB guide. Use supported local WiFi sync for a phone–computer workflow in both directions.
Some builds export only entries not already synced. Check the exported entry count and destination history instead of expecting a duplicate of every note.
Check that the phone is unlocked, MTP is selected and the cable supports data rather than charging only. If the controls are missing, check your app version and use the supported export or WiFi options.
