compare contents - "access denied on file"

[nimbus]

I got "access denied on file" error when use "compare contents" command.

First I tought it is because nas server security settings (qnap)
I activated windows ACL rules on server and checked R/W permitions of folders for users. (actually I access to server as admin rights).

Second, i checked from Pc side that "full control" of folders from security section of the folders that I compare (ALT+ENTER)

Third I updated TC to 9 B2
Still it is not possible to compare dirs by contents.

I noteced this error not related only nas server.
I have another pc which runs windows 10 home single lang and gives same error for compaing folders on internal drive C

Are you able to view the file contents with F3? If no, the file may be locked by some other process. If yes, then some permission doesn't allow to map the file into memory.

Sorry for taken your time.
Looks I've picked the wrong command what I wanted to do.
Understood that When I execute the command "compare by content" on folder but not a file, access denied error occured.
"Sync dirs" command works perfect and what I'd needed.

Sorry again

You are right, the command doesn't work for folders. But the error message could be more meaningful.

BTW, this was already reported in the past: http://ghisler.ch/board/viewtopic.php?p=278132
