File Timestamp

Easily change the last modification date and time of your files. This app requires ROOT access and BusyBox.
On Android OS, every time you copy a file, the last modified date of the destination file is not preserved. For instance, if you copy an image file (i.e. picture), the Photo Gallery app will show the new file in the wrong order.

Use File TimeStamp to change the last modification date of your files.

This app is particularly useful when copying files between devices. Run the app on the original device (does not require root on that device), copy your files and an additional text file generated by the app to the new device. Run the app again on the new device (with ROOT access) and easily change the date of your files.

File TimeStamp also allows you to change the date of all your files at once, based on their file name or imagens based on EXIF Tag of JPEG files.

You can change the date of a single file or in batches.

The application currently supports the following masks:

WhatsApp:
IMG-[yyyyMMdd]-WAnnnn. Eg: IMG-20161201-WA0001.jpg

Ignores all non-numeric characters and considers yyyyMMddHHmmss (first 14 digits):
Examples:
20161231010101.jpg
20161231_010101.jpg
IMG_20161231_010101.jpg

Ignores all non-numeric characters and considers Unix TimeStamp (miliseconds since 1970):

If your images have a different mask, send us an email and we will evaluate the possibility of including it in a new version.

Note about WhatsApp image (since they do not have time information in the file name):
IMG-20160424-WA0001, file timestamp = 04/24/2016 00:00:01.
IMG-20160424-WA0082, file timestamp = 04/24/2016 00:01:22.
