file currently in use?

[Anonymous]

I have a user who's got an error on both Acad and Inventor (2019 both) for files he's working on.

After he's logged in and open the application, he gets the error saying the file he's attempting to open is "currently in use by (his user id)" and then asks if he wants to open as "Read Only".

What may be causing this and more importantly, how does he clear it? He's shut down completely for at least 15 minutes and still gets the error.

Thoughts?

I get similar messages about being in my own way all the time, and not necessarily just from Autodesk software (biggest offender for me is Excel).  Does your user happen to be working on a network drive?  That's where I tend to see this problem (which is unfortunate because that's where I do most of my work).

Hi Jim and John,

Indeed, it could be network or Windows related. For whatever reason, Windows thinks the file is in the memory. One thing you could try to change is to disable a Windows service called Superfetch. Go to Task Manager -> Services -> sort by description. This service would cache frequently used files in memory. In theory, it should never interfere with how Inventor works. But, nobody knows what it is doing behind the scene.

The reason why I suspect it could be related is that you mentioned it happened to AutoCAD also. The way Inventor manages memory and files is quite different than AutoCAD. When it happens to both, it means something else might be at play.

Many thanks!

In my case it seems to be related to windows that is also slowing the overall performance as well, following the given lead i disabled it with some additional steps to service host superfectch and now Acad files execute swiftly..

Thanks for the info, I have the user changing such and we'll see if it helps.

OK, so I've had a couple of users do this "fix" and all except one says it's improved load time and working time (I assume they mean reaction time working within the file).

Considering users here typically will have Inventor, AutoCad, Vault Explorer, spotify, Facebook, youtube, etc all going at the same time, I can assume Superfetch is grabbing and holding a good portion of their RAM.

I won't get into the one person who claims it's actually making things slower...
