path = './file.txt'
os.remove(path)
import os

os.remove(path) is equal to os.unlink(path), so how can I delete the file if it just becomes unlinked?

Also I haven't tried to yet, but does './file.txt' work as is or do I must provide the full path?
Or do I just need to use the 'file.txt' if it the same folder? Or they both work the same like os.remove(path) and os.unlink(path)?

And if './file.txt' works then what about '../file.txt'?

When you say "delete", what exactly do you mean? Scrambling the file? Because when most people say "delete", they mean "removing the file system entry", which is exactly what remove/unlink does.

You can use relative as well as absolute file names. So all of 'file.txt', './file.txt', '../file.txt' and '/path/to/file.txt' will work.

By delete I mean free up the physical space.

Although now you bring something else to my attention because I know about data recovery so if I rewrite the file and then delete it will that be the most secure deletion?

with open(path, 'w'):
    os.remove(path)

And will this work for any type of file? Like say an executable, or will it only work for text files?

I don't wanna unlink it but have still have it lingerieng around cluttering up my hard memory.

open(path,"w").write("")
os.remove(path)

Will that zero out the bits and bytes?

[sepp2k]

If there's no file system entry for a file, it does not consume space. Zeroing the bytes of a file will not make it consume less space, but it will make it harder to recover the file after you delete it. However writing the empty string to a file before deleting it will not zero the bytes. It will do basically nothing (it's pretty much the same as deleting the original file, creating a new empty one and then deleting that as well).

If all you want is to free disk space, just delete the file with unlink/remove.

But open(path, "w")? The "w" overwrites the file, so open(path, "w") all by itself has removed the file and placed a new one in its place with under the exact same name?
I guess I should have thought of an overwrite as a write over.

Fine then how can I zero the bytes and bits out?

And what about open(path, "r+").write("something") and open(path, "a").write("something") won't that change the bits and bytes? Or does it just unlink the file and write a new one it its place?

unlinking bypasses the recycle bin folder?

[Gribouillis]

Python only wraps the lower level system functions which open a file to create a file descriptor or a pointer to file, and the corresponding read or write functions. So, for example you could ask in the C forum if fopen() with mode 'w' physically overwrites existing contents on the drive, or if it may write in a different place.
