DELETING FILES
Liberty BASIC allows us to delete files with the KILL command. Note that they will not be placed into the recycle bin. They will be permanently deleted.

syntax:

KILL filename$

In the above example, filename$ must be the name of an existing file on disk. If you try to KILL a file that doesn't exist, the program will halt with an error. If the filename$ doesn't contain a path, it is assumed to be in the same folder as the Liberty BASIC program. This folder is contained in the variable DefaultDir$. The following little demo creates a text file, then kills it. The file is created in the DefaultDir$ because no path information is included in the filename$ parameter.

open "hello.txt" for output as #f
    print #f, "hi"
    close #f
    kill "hello.txt"

Here, we let the user choose a file to delete:

filedialog "File to Delete","*.*",filename$
if filename$="" then 
    print "Cancelled!"
else 
    kill filename$
    print filename$;" deleted!"
end if

RENAMING FILES (MOVING FILES)
We can rename a file with the NAME statement. Files can be moved to other folders using the NAME statement. To rename the file, "readme.txt" to "message.txt":

NAME "readme.txt" as "message.txt"

To move the file, "c:\info\readme.txt" to c:\myfiles\readme.txt":

NAME "c:\info\readme.txt" as "c:\myfiles\readme.txt"

Just as with the KILL command, an attempt to NAME a file that doesn't exist will cause the program to halt with an error. Also, as with the KILL command, if no path is given for the filename$, it is assumed to be in the same directory as the program, which is the DefaultDir$

Here is a demo that allows a user to rename a file.

filedialog "File to rename","*.txt",oldfile$
if oldfile$="" then end

filedialog "New name","*.txt",newfile$
if newfile$="" then end

name oldfile$ as newfile$
