Exclusions for Offline Files

Where do I define file types that I want excluded from Offline Files synchronization in XP Pro? Or is it a folder-by-folder situation where I'm going to have to remove all the .mdb & .pst files out of the folder that is being sync'd? Thanks.

Hi WineGeek,
My first thought is virus or spyware that trying to block you from killing a task.  May, maybe not, I don't know.

But I also thought that an update or application installation may have made an unexpected change.  Have a look at these pages and see if they help:

Hope this helps,

oops.. sorry wrong question....

Let's try this again.

What you want is a group policy setting adjustment.

This page (http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/prork/prde_ffs_curs.mspx?mfr=true) talks about it ("Files not cached") in table 9.9, near the bottom of the page.

Hope this helps,


Nope, they just send me around and around cross-referencing too many "See blah blah bah mentioned in Chapter blah blah..." and I ended up back where I started...... thanks for the effort though.

On Windows XP (Pro, not Home, but Home doesn't do offline files anyway....) to open the Group Policy Editor do:
In the Group Policy Editor, in the left pane browse to:
Local Computer Policy>Computer Configuration>Administratove Templates>Network>Offline Files
In the right pane double click on Files not cached to open the properties window
In the Files not cached Properties window Enable the policy and specify the file types in the text box below.  For assistance on the policy have a look at the Explain tab of the Files not cached Properites window.

Note that by default some file types do not cache.  According to the section entitled Overview of Offline Files and Folders in the document referenced in my earler post, this policy will override that default, so for safety I would suggest including the follow types in the list:
*.SLM; *.MDB; *.LDB; *.MDW; *.MDE; *.PST; *.DB?

Hope this helps,

Well, I closed this question too soon - that didn't work. I create the policy but it still shows these error messages at the end of the offline file synchronization at logoff that says this file and that file cannot be made available offline. What I want to accomplish is to eliminate these error messages altogether. Do I need to open a new question to continue troubleshooting this? Thanks.

Humm...  error messages... notificiation messages... hum....

I'm thinking that what you are asking and what I am saying are the same... but different...

If you are talking about the message at the end of the sync, that's not technically an error message, at least not in my opinion.  It's more like a notification or status message.  Some files do not tolerate sync'ing very well, which is why there are a handful of them that are set, by default, to not attempt it.  These files are database type files like MDB, PST, etc.

I believe that you are trying to set the system to not show the message.  I think that the only way to do that will be to either set the syncronizer to sync those special files (although not really recommended), or move the files out of the folder that is set to syncronize.  Following the advice in my earlier post should allow you to sync the files that are causing the problem for you, but be aware that it could cause problems later.

Hope this helps,
