Batch Script: Check if File exists

For checking whether a file exists, you can just write "IF EXIST".

Behind that, you can write the file name and the action that should be executed in the case that the file exists. Here is an example:

IF EXIST c:\test.txt notepad c:\test.txt

With this line, first, it is checked, whether the file c:\test.txt exists. If yes, the file will be opened in the program notepad.

If you want to check for nonexistence, you can use IF NOT EXIST:

IF NOT EXIST c:\test.txt ECHO file does not exist

This writes the text "file does not exist" into the console if the file c:\test.txt is not existing.

If you cannot or do not want to write all commands into one line, you can also use the following syntax:

SET F="c:\test.txt"

IF EXIST %F% (
  ECHO %F% is existing
) ELSE (
  ECHO %F% is not existing
)

Additionally, I have worked with a variable in this example. "F" is first set to our file and afterwards, it is invoked with %F%.
