Ed:

After all, it was a bug in XXCOPY!

/ex"c:\dos\bats\_clonenot.txt"

is a valid syntax but XXCOPY failed to handle it correctly.

This is not the first time that I made an assumption that
the XXCOPY program was working right and blamed the user
for the difficulties and the problem turned out to be a bug.

It's always embarrassing to blame the user for a legitimate
bug report. Usually I pay attention to who made the report.
In your case, I should have known better. I recall you are
an advanced user who would not report a false bug-report
(in this particular case, the user could easily checked
whether or not the file exists --- on the other hand, some
novice users who specify a bare filename (without its full
path) and often never find it!!!).

Any filename for /EX or /CF which is inside a quoted string
(which is a valid syntax even if you don't have an embedded
space) should be accepted. We will release a fix shortly.

For the time being, please select a filename whose path
does not have an embedded space and remove the quotes
which are not handled right by XXCOPY.


----------------------------------------------------------
The bug which was apparently introduced in recent versions
which support a separating colon between the switch
alphabets and the optional parameter. We changed the
command-line parsing code when we started to support this
feature to improve the readability of the command
(mostly useful for the /CF command text see XXTB #37).

That is, now you can say

/X:*.mp3
/ON:c:\temp\mylog.txt
/CF:c:\bin\myscript.xcf

We had a messy syntactic collision with this scheme
with the following pair of switches,

/SZ // copy first n bytes
/SZ: // select files of n bytes

The culprit of this mess was we did not think carefully
when we added the /SZ switch for our internal
consumption which eventually became an official switch.
When we added /SZ: (with its variation) to select
files based upon the file size, we just could not find
any better mnemonic for the function. Now, we are
gradually phasing out the /SZ switch which is now
being replaced by the new /TR switch which performs
the same function (Truncate at n bytes).

As soon as we phase out the /SZ switch completely,
we will publicize the syntax for the optional colon
more openly.
