Question: Cache Flush

[Anonymous]

What is the ADSK recommendation for flushing the cache folders (both PacCacheCollaborationCache) to keep from getting backed-up?

[Chris.Aquino]

There really isn't a recommendation for clearig the caches. In fact, clearing the collaboration cache will cuase users to incur the "first open penalty" where revit needs to download the entire composite model (host file and any links) on Open.

What do you mean by "getting backed up"?

'backed-up' as in not unlike when a toilet gets 'backed-up'.

we understand the concept of 'first open penalty'. in our case; between users' bloated pst (outlook) files, various 'temp' data within the ..\%LOCALAPPDATA%\ dirs, other windows temp filesl, etc,..and the 2 C4R cache folders, keeping enough local disk space available for the C4R cache is becoming a challenge as the daily increase of C4R revit cache files grows really fast. Overtime it doesnt seem neccessary to have to keep all those older cached revit files.

Ahh, ok.

The reason for the caches is to increase performance within Revit, so clearing them out regularly would slow Revit.

If you have Revit files in the cache which haven't been touched, they should get cleared out automatically after a few days of inactivity (or you can clear them out manually).

really? wow, that's good to know. is there a way to control that process, or to know the frequency of the auto-clear process?

when you mention "should get cleared out automatically after a few days..."; ok, thats great. But how does that work? we would like to know where is the automatic process controlled at? who controls it - C4R, windows?...adsk black-magic?

also, clearing the cache manually is ok with us (automating that via a log-on script), but how are we supposed to know which model is what in the cache?

Thanks for you help and info! much appreciated.

[Chris.Aquino]

At this time, there is no way for end users to control the process, as it's controlled through the personal accelerator.

As far as the frequency goes it's somewhat squishy depending on activity and file types, but around a week of inacitivty would be pretty normal.

As for finding which file is which, the following article has information on how to do that:

Ahh, ok... thanks, so in other words it is, black-magic. 😉

thanks for the info.

it doesn't automatically clear, i have revit from previous years and the cache files are still there.

thanks

It's my observations that they do not get cleared out automatically.

The user should be deleting them on a regular basis along with regular computer maintenance of clearing temporary folders.
