Deleting files equal to 0 in a batch file
Below is an example of a simple for command that could be put into a batch file to delete the "pics.txt" file if it existed and was equal to 0. In this example, you would need to know the name of the file.
for /F %%A in ("pics.txt") do If %%~zA equ 0 del pics.txt
If you are looking for all files equal to 0 you would need to create a loop and a similar command for this to work is shown below.
FOR %%F IN (*.*) DO (
IF %%~zF LSS 1 DEL %%F
The above example will go through all files in the current directory, and if less than 1 in file size, delete the file.
