Some Help Pls, with Deleteing files

**danward79** · April 17th, 2004, 11:58 AM

Hi

I have been writing some scripts for burning my sage tv programs to dvd

It works great, I managed to use dvdspy to tell if a disk is present, etc, and get user feedback for a seemless interface.

What i need to work out is how to remove files from the temp directory leftover from burning. IE. Like in dos "del *.*"

Also how can i remove a directory? I have been playing around with remove in lua, but it does not like *.* !!

Any help you can give will be received with many thanks...

Dan, have a look at the luacom thread (sticky post). There is a reference to the filesystem object. This will let you do most any file operation you want.

Hi

I am still having problems with this, I have tried the os.remove command and various others but, as i am not a programmer am struggling to get it. I tried to create a function that did not work either...

Do you have an example of how i can do it, I looked at the sticky posts and the lua docs, + all the links, but it don't work

I am also tring to get the size of a file, the idea is that if it is bigger than 4.7Gb I want to run a program called rejig to make it fit a dvd, it is so I can record tv shows if I want to keep them to DVD.

I assume, once I understand how to create a function for delete I should be able to easily create one for getting the size of the file?

So... In advance thanks for any Help

Cheers

Ok,

Using Lua (Variable Manipulation Script.

LoadLuaCom ()
fso = luacom.CreateObject ("Scripting.FileSystemObject")
fso

eleteFile ("\\\\C:\\test.txt") == 1 then
fso = nil
collectgarbage ()

Notes: In Lua, the “\” is an escape character and double “\\” equal one “\”. COM Objects use the C conventions for true and false (1,0) where as LUA uses non-nil and nil.

See: http://msdn.microsoft.com/library/de...filesystem.asp

Hi Mike
I don't get it, I now have this error!...

error: COM exception

.\src\library\tLuaCOM.cpp,357):The parameter is incorrect.

stack traceback:
1: method `DeleteFile' [C]
2: main of string "?" at line 3

Cheers

Don't WorryI have done it!

I had to change the code you gave me to this

LoadLuaCom ()
fso = luacom.CreateObject ("Scripting.FileSystemObject")
fso

eleteFile("C:\\*.log", 1)
fso = nil
collectgarbage ()

it did not seem to like the \\\\ before c: , what does \\\\ that do?

Cheers

Dan
