Origin Ver. 2021 9.8.0.200
Operating System: Win 10 pro 64bit

Hello together, I like to copy a file to another location.
After using the labtalk manual I found "file -c".
I tried this with some .txt files and it worked great.
Now I like to copy some .tdms files and the location (in and out) should be a string variable but it seems that this doesn't work. Some ideas why? Is there a better way copying files to another destination?
Thanks in advance

Would you please attach the script that you used? I couldn't reproduce the issue.

Hello James, thanks for your reply.
In general I used:
file -c C:\User\Test1\Test.txt C:\User\Test2\Test.txt

After this is tried:
String dest1$ = "C:\User\Test1\Test.txt"
String dest2$ = "C:\User\Test2\Test.txt"
file -c dest1$ dest2$
but this doesn't work.
Syntax issue?

This LT command was very old, way before LT string variables were introduced and apparently we failed to update it, we will do it for upcoming Origin 2022, for now, use the % substitution, see below:

string str1$="C:\temp\test1\test.txt";
string str2$="C:\temp\test2\test.txt";
type -v "copying from [%(str1$)] to [%(str2$)]";
@ERR=0;
file -c "%(str1$)" "%(str2$)";
@ERR=;//from system GetLastError if CopyFile failed.


Please make sure you have write access to the destination as c:\Users\ typically is not writable.
