windows - Create a backup before deleting each file in a batch file -


i have folder has several files .txt extension. need delete them before need take backup of it.

for example, assume have folder following contents: 

name1.txt   name2.txt    name3.txt    name4.txt

after delete, contents of folder should be: 

name1.txt.bkup   name2.txt.bkup   name3.txt.bkup   name4.txt.bkup

how can done?

just rename .txt-files .txt.bkup, i.e.: 

rename *.txt *.txt.bkup

if insist on creating backups before deleting (for example, configurable batch file, creating backups may switched off), can copy files before deleting: 

copy *.txt *.txt.bkup del *.txt
