FAQ
Q1: This app is not working on my Android 8+ phone ?
A1: Most Android 8+ systems prevent applications from running in the background, please check system settings and allow this application to run in the background. Please select schedule option "Instant (With Notification)" in the setting, if the notification is not displayed, it means the application was killed by the system.

Q2: Why the file was transferred before the download completed?
A2: The only way for this app to know if the file has been edited is to detect if the file size has changed within the "Transfer Delay Time After Detection" (default is 1 second), you can set a higher value (Transfer Delay Time After Detection) to prevent this from happening. In addition, if some apps are editing a file, a temporary extension is added to the file (eg ".crdownload", ".tmp"), you can add that temporary extension name in "File name filter(blacklist)" with option "End with" to prevent this app from transferring that temporary file.

Q3: Why the video was transferred before it was taken ?
A3: Same as Q2, please refer to A2.

Q4: I cannot find my SD card when selecting source or destination folder
A4: When you press the source or destination folder, you will be taken to a page provided by the Android system (not created by us) to grant permissions, you can click the "More" button in the upper right corner to show more storage space location.

Q5: Where is my activation code ?
A5: After an in-app purchase, a dialog will appear asking you to enter an email address to receive the activation code. After that, the app will be automatically upgraded to premium version.
