I am working on a batch file to create an automated archived backup that I will schedule every 2 hours to run.  It works until it gets through to the end of the script.  Then I get the error 'A duplicate file name exists, or the file cannot be found.'  What is wrong with me?

@echo
copy file.txt backup
cd backup
if exist file4.txt ren file4.txt file5.txt
if exist file3.txt ren file3.txt file4.txt
if exist file2.txt ren file2.txt file3.txt
if exist file1.txt ren file1.txt file2.txt
if exist file.txt ren file.txt file1.txt
del file.txt
pause

You have this:

  if exist file.txt ren file.txt file1.txt
  del file.txt

First you rename file.txt, then you try to delete it.  I suggest this instead:




@echo
copy file.txt backup
cd backup
if exist file5.txt del file5.txt
if exist file4.txt ren file4.txt file5.txt
if exist file3.txt ren file3.txt file4.txt
if exist file2.txt ren file2.txt file3.txt
if exist file1.txt ren file1.txt file2.txt
if exist file.txt ren file.txt file1.txt
pause

at the end of the batch you are still in the backup directory. Try changing the end of the batch to

if file.txt exist del file.txt
cd ..
pause

Oh also make sure your file.txt file is not a file.txt.txt file. Remember that windows by default hides common extensions so file.txt.txt will look like file.txt in the directory.

Ok.  I see.  It gets to the last iteration, then it renames file.txt to file1.txt.  Then the next command is to delete, but there is no file.txt left and fails.  Nice work!
