File Content Query

[Derek S]

Hi all,

I’m using donation edition to move folders, sub folders and files to a new empty drive. As the original data will be migrated and used ongoing on the new drive, I need to make sure the files are identical at bit level.

My question is, If I use the files contents check rather than date and file size option on the first run to copy the files, does this check file contents as it goes or do I still need to to a file contents check on completion?

The reason I ask is that after a couple of trial runs, the time estimated to complete the first run using either method is the same (circa 2 hrs for video file folders), which seems a bit odd given the extra checks if they are indeed made on copying the files for the first time.

Thanks, Derek S

By default, FreeFileSync (FFS) does not check file content upon copying the files over.
However, you can change the VerifyCopiedFiles flag from False into True.
But, make sure to read the text regarding the VerifyCopiedFiles flag (and possibly even the external link).

The only way to make absolutely sure the file contents is identical is to make sure any cached data is flushed (at either side) after running the sync that copied files over, and then run an Compare by content.

Thanks Plerry,
That’s clarified a lot, especially with the links.
