Hi all,
Discovered a scary bug when Mylio overrides “Creation Date” of files stored on external drive Vaults formatted with ExFAT.
I primarily use a Mac OS Device as a host for several external drives (4TB HDD) formatted with ExFAT for compatibility with Windows PCs.
As I’ve discovered with horror last night, is that when Mylio copies files to the ExFAT drives, it overrides the “Date Created” to the time of the copy, thus effectively changing the original. That is especially damaging for video files, as they don’t have original creation date in the metadata.
The “Date Created” is also changed if you make any changes to the folders structure in Mylio (e.g. reorganize folders).
“Date Modified” is remained intact.
When tested manually (by copying files to the disk with Finder), the Date Created is preserved. So this is definitely a Mylio bug.
When tested with NFS (Mac OS Journales) formatted disk, the Date Created is correctly preserved.
Hopefully I have a full copy of the files on my NAS device, that was synced from originals (and not from the ExFat vaults with bogus timestamps) and now doing a restoration using clean hard drives.
I’ve issued a critical support request to Mylio to fix that, as changing files metadata is not what I expect from a software that syncs data across devices.
For those who uses or plans to use ExFat drives - you’ve been warned.
In the meantime, if anyone has come across this and found a solution to clean up the mess - please share. If not, I’ll be working on a set of scripts to validate/correct the timestamps (thankfully I’m a software engineer, so can automate restoration).
