I have tried the following to copy the files in Data to another location but received the error "invalid parameters." What is wrong with my command?

C:\xcopy c:\ProgramData\MySQL\MySQL Server 5.7\Data c:\DataBackUp

I have Windows 10.

Your source folder needs to be enclosed in double-quotes like this:

C:\xcopy "c:\ProgramData\MySQL\MySQL Server 5.7\Data" c:\DataBackUp

Otherwise the XCOPY command sees the following as separate parameters:

  • c:\ProgramData\MySQL\MySQL Server
  • 5.7\Data
  • c:\DataBackUp

It expects two paths, not three, hence the "Invalid parameters" error.

As a side note, it's only necessary to specify a path to XCOPY (e.g. C:\xcopy) if you really have a copy of the executable in the root of C: and intend to execute it from there. If not, just start your command with XCOPY.

  • Tks. But, now I get this message : Does C:\DataBackUp specify a file name or directory name on target (F=file, D=directory)? and I just typed D. And then a bunch of lines came out. What should I do to ensure all the files in Data get copied into the DataBackUp folder? Will windows 10 recognise that is a folder? – Karen Goh Oct 16 '18 at 2:42

    @KarenGoh add a back slash to the end of the destination path to tell XCOPY it's a folder, like this c:\DataBackUp\ – I say Reinstate Monica Oct 16 '18 at 2:43
  • Now, I have this SQLTable -hi5 and other tables inside but it is not copied. And these are the things that I really make a copy. How come Windows do not copy all these files into my DataBackUp and only copied otheres like ibdata1? – Karen Goh Oct 16 '18 at 2:54

    @KarenGoh This sounds like you're facing a different problem. On this site we ask one question per problem, so please post a new question. – I say Reinstate Monica Oct 16 '18 at 2:57
