How to sync two folders if source files are opened?

[postcd]

Hello,

im trying to sync two folders on my computer periodically and the source folder is my Firefox browser profile and i have Firefox opened nonstop. What are ways to synchronize two Windows 10 folders even if files in source folder are opened?

Im using Microsoft's SyncToy and it complains that it cant copy around 30 files because they are opened and 2 files cant be coppied because source file was modiffied during sync.

It is vital for me to sync because my source drive is a RAMDrive.

Thank you

So whenever you boot up your PC, you copy your backed up Firefox profile to your RAM disk, then launch Firefox and repeat this whenever you shut your computer down? I was going to recommend FreeFileSync, but I've received errors about files having changed since the sync was started as well, although that can be configured to ignore it. FreeFileSync can be run manually or automatically.

Im not shutting down the laptop frequently, when i sleep it, data stays in RAM.
FreeFileSync looks to be nice tool, it works and also sync via sFTP. It sync even opened files (in settings is feature: copy locked files).
I only needed to filter out file *\parent.lock which canot be copied from Firefox profile folder.
FreeFileSync also allows saving the sync project as a file that can be run from the Windows desktop or from batch file. Once run it automatically do the sync and outputs message at the end.

PS: xcopy is alternative to windows "copy" command and with "/H" parameter it copy even hidden & system files. Not sure if opened files.
