When an FTP user uploads a file to FTP to an empty directory, then
renames/moves the file to another folder where the samely named file
and even being served by Apache, it simply works! How does this work? I do
not think in Windows you can overwrite an file that is being read. Could
somebody let me know please?
Sure you can :-)
An open file can be renamed without affecting the program(s) having the file
already opened: any file handle still refer to the opened file. Then once
renamed, you can write an new file with the old name.
I use this trick to have a exe updating itself while executing.
