Between yours and Crystals help I have a functional folder hierarchy creator.... Thank you that was a huge step. Now the next step is the user step through a series of combo boxes to get to the folder that they want now I need to load all the files located in the specified folder into a subform called sfrmFiles...

OK, I understand. God bless "Management" :-)
The next question then, is "Do you want to duplicate the hierarchy of folder and file names in the Access database (and risk it getting out of sync every time a file is added or deleted) or do you want to populate the combo/list boxes directly from the folder structure?
Best wishes,
Graham

Hi Art
I can't help but think you are trying to reinvent the Windows File Explorer!
Is there any compelling reason to reproduce the file system folder/document hierarchy in Access?
Best wishes,
Graham

Subject: [MS_AccessPros] Creating a folder structure based on combos?
Currently writing a document management system in Access and would like to know if the following is possible:
I have my home screen called frmMain. On this form I have a cboCabinet (unbound - row source: SELECT tblCabinet.intCabinetID, tblCabinet.txtCabinetName, tblCabinet.txtCabinetLocation FROM tblCabinet; ) which is at the highest level of the hierarchy.
Then is the combo cboDrawer (unbound - row source:SELECT tblDrawer.intDrawerID, tblDrawer.intCabinetID, tblDrawer.txtDrawerName, tblDrawer.txtDrawerLocation FROM tblDrawer; which is the secondary level of the hierarchy.
Thirdly is my combobox cboPriFolder (unbound - row source: SELECT tblPrimaryFolder.intPriFolderID, tblPrimaryFolder.intDrawerID, tblPrimaryFolder.txtPriFolderName, tblPrimaryFolder.txtPriFolderLocation FROM tblPrimaryFolder; which is the tertiary level of the folder hierarchy.
Lastly is my listbox called lstSubFolder (unbound - rowsource:SELECT tblSubFolder.intSubFolderID, tblSubFolder.txtSubFolderName, tblSubFolder.intPriFolderID FROM tblSubFolder; This is the last level of the folder hierarchy.
on frmMain, this combination of combos and lstboxes is used to set the working folder.
So the following actions need to happen:
1. the root of the folder hierarchy is always c:\work but it could be mapped out to a server drive
2. I have a frmCabinets which the user use to create the folder hierarchy. At this point I need to the mechanics to create the actual folder structure based on the combination of combos and list boxes. ( I have uploaded a few snapshots of what frmMain and frmCabinets look like to the Needs Assistance folder.
3. Once the user sets the working folder, then I need to display a list of files in that folder. The user should be able to open any file in its natural application.
4. The application will need to remember the last selection in the combos and listboxes and working directory each time the user logs off and logs back in.
I know its a lot and as I go along I suspect I will have a lot more questions....
Thank you,
Art Lorenzini

Ps. pictures will be uploaded shortly.
