is it possible to make a mirror copy of excel files.

Hi,

*Personally* I would use a standalone backup-software instead of XL and scheduled the copying.

1. I think it can´t be done directly to his harddisk only to his account on the server.

2. If You want to do it in XL You need to consider to create a add-in, that is distributed to all co-workers.

You need to decide wether You want to use the old DOS-commands in XL, like copy dir etc (see the directhelp) or using the File System Object (FSO).

The later require a reference to the Microsoft Scripting Runtime library via the Tools | Reference... in the VB-editor or through the CreateObject.

You can read more about the FSO here:

Anyway, at this stage I don´t I can contribute with more.

Kind regards,
Dennis

I hopr this helps if you wish you can edit the codes its all commented, i wrote this for someone at work some time back and as such is unedited, things have moved on from here, but this is the original as was, and is still used to this day.
