you're welcome, Kevin
when browsing, if a user identifies same file that is already attached to another record, the file does not need to be copied again (use code to detect that). This is a big advantage to attaching information to each record in the database. An analysis of one database with a lot of attachments found that only 30% of the "attachment" files were unique when they were converted to external files again since it is common for more than one record to reference the same thing (not counting things like human photos). Aside from better performance, there can be less wasted space with duplicates with files as files. Also, external files are easier to render, especially when versions change.

Hi Kevin,
adding on since I don't know how you are using these folders ...
I normally hang folders off the back-end directory for shared images and shared files. I also have an interface to move/copy and then rename files they want to include -- but VBA does it all, they do not need to browse themselves except to identify the source files in the windows dialog box. This is a convenient way to keep external files as files and move/point to the back-end and everything it needs to reference. I have code to get that BE directory for each user and then tack on whatever subfolder may be needed such as \images. Users also need permissions for the back-end subdirectories too.

I got it. I think I'd better not to enable the accessibility to the backend folder. Thanks a lot.

So, you open the folder for them, and then what do you expect them to do? Unless you use Windows security, you can't prevent them from going to other folders.

I want the users to store relevant docs in the same folder where the backend locats. You know there might be several users handling the same tour group. They can get access to same folder.

No, you can't prevent them. Why are you opening a folder? What is it you want the user to do or see?

Dear All,
I use the following code to open up a folder. My question is how to prevent users from browsing directories out of this folder? Thanks.
Shell "C:\WINDOWS\explorer.exe"""" & strPath & strfolder & "", vbNormalFocus
Thanks,
Kevin
