Moving files from a location to another one (such as from internal memory to external SD card) will make G Cloud back them up again since the modification date of them will be changed.
To address this, please apply the following:
- Wait until G Cloud finishes uploading the files.
- Tap the Restore button.
- Tap the name of your device.
- Browse your backup and go to the old location where those files have been saved before you moved them.
- Once you find the files, select them by simply long-press on them
- Tap the Delete button.
Do not delete anything from the backup this way unless you are 100% sure you do not want the file anymore. The delete action cannot be undone, and the deleted files will not get automatically backed up again unless they are modified.
