Md5 checksum files have been the gold standard for 25 years.
It was so simple on a pc. Run the crc software, create the tiny crc text file. Store it with your data. You can right click with a mouse on a crc file and verify the checksum.
I can’t find a way to do it on Android. I installed an app, MD5 checker. It’s almost useless. It doesn’t create md5 files. I tried to do a checksum on a movie backed up to Google. It copied a 5GB file back to my phone!
I’m already way low on disk space. That’s why I purchased Google drive space for backups.
There has to be a simple way to verify a checksum before deleting the original?
What am I missing? Is their a checksum feature in Google drive App?
It seems crazy to blindly copy to Google drive and delete the original without a checksum.
