Anybody know if DirRemove() will finish before next line of code?

Most specifically I am wondering about DirRemove()

In my use it seems like it will start the deletion process and instantly move onto the next line of code even if the computer still has a good while to go before it has actually deleted all of the files.

The other commands of similar feature that I also wondered about are.

DirCopy()

DirMove()

FileCopy()

FileMove()

FileDelete()

It seems to me the copy/move commands do wait but the delete commands I think do not.

Just looking for verification so I know if I need to add some extra code to account for waiting on the machine to finish a process before trying to work with that file space.

I have searched and there is a thread just like this almost already but nobody actually answered the question just came up with some code that could work around the problem if it did exist. 

Plus AutoIT is always changing how it works, some of those older threads are not even accurate compared to the newer versions we have now. 

Thanks Guys,

Yes there is bound to be 100 different ways to code it to work around it.  But I want to know how the function is supposed to operate out of box. 

My largest "hunch" right now is that in many cases say you were deleting a folder with 10GB of info.  The folder may disappear in 5 seconds but the drive may be doing "background" tasks to finish off all that data deletion for the next 20 seconds.

So if you were trying to call a loop to check for the folder it may appear as if its gone but if you tried to work with that file space and install something the installer will fail and tell you that files are on the disk and ask to overwrite. 

Perhaps once the question is answered we can discuss some ways to script a good and easy work around. 

I imagine loops or a simple if fileexsist() are easy solutions, if my theory above is true about waiting on "invisible" tasks it may be best to go cave man style and simply Sleep()

The next line in your script won't be completed until DirRemove() has done its job, just like most native/UDF functions. So on to the workarounds.

Well then if it wont move on until its done, we would not need a work around correct?

I am only going by memory but I remember doing an Oracle install and using DirRemove() to take out the old install because if I tried to repair an installation and install over it I would get dozens of additional windows at random asking me to overwrite the old files.

Originally just throwing in DirRemove() by itself, I seem to recall getting some issues with the installer failing after because part of the deletion process was still in use. 

But I was in a pinch working fast and long hours, put Sleep() in there as the easy fix and have not had issues since.  Deciding now to revisit it so I can perfect my methods.

Well I don't need a workaround, I thought you do?

I can't see a good reason not to put in @error If statements after all of these if it's mission critical to the program running. I am really curious to know why it is important to delete a folder super fast. What if it takes 2 seconds?

There are some cases where a computer is lying to you.

The most common is the disk subsystem lying to the OS, returning a "Done" status while in fact the data supposedly written still hasn't reached the magnetic or solid-state media safely and in full. Typical consumer-grade disks lie thusly, sacrifying integrity to speed.

A corollary of slightly higher level is the command queuing and reordering by the disk firmware and cache.

One level higher, there is the OS (and admin) allowing a write cache. The data and commands stored there are not even passed yet to the disk firmware.

What you observe is yet another level of OS lie: a complex filesystem operation is requested and after acceptance a "Done" status is returned to the caller.

It's really hard to protect agains such multi-level lies over which you can have little or no control, short of using subsequent and reliable mean to check that the requested action has indeed taken place. The term "reliable mean" is important: reaing back some cache means nothing! In all cases you can't guard against the disk firmware lying to you except if you use exclusively serious server-grade hardware (disks + controller) allowing control over disk write cache setting, (i.e. not all) AND accept the huge accompanying disk subsystem slowdown.

These issues are of premium significance to databases engines, which are compelled to perform ACID transactions.
