portability and "sensitive" files

[Admin]

I need to correct myself,
"local state" needs to be copied because it contains chrome://flags settings,
while, on the other hand files that are causing problems are "preferences" and "secure preferences",
these files contain extensions settings but extensions don't work in another pc in chrome portable
(the same with passwords - but those are synced anyway - etc),
they are synced though, but not mine, because mine are unpacked,
so I would be needing to setup my extensions in each and every new installation
so chrome portability sucks anyway..

I found this for reference and this was what was happening when I was trying to set it up in another computer:

also, when you transfer "preferences" and "secure preferences" to another computer breaks sync in
the original pc you took the files from (that's what happened with latest cent beta too - based on chrome 74)

If you need to copy User Data files between computers, you should better turn off sync firstly.
