Hello everyone,

I have to remove all my folders and my models from a "normal" path (I:) to an UNC path (\\mypath\myfolder).

Here is the problem because I have models working with releases before the R2009a like 2007 or before.

Matlab/Simulink seems to be unable working with this king of path and build an error : "DOS commands may not be executed when the current directory is a UNC pathname"

I have seen on MatWorks some different subject like this being aswer by

"To work around this limitation, change the folder to a mapped drive before running dos or a function that calls dos."

But my aim is to make free my I: because all the other letters are already full. ^^

I may wrong interpreted this answer because I am not a network expert but for now I don't know how to bypass this problem to build my model for release before 2009a.

Thank ou for your answer!

在 MATLAB Online 中打开

If your computer uses all drive letters already, it is polluted and messed up. If you really want to work in such a strange environment, such problems are expected.

The message "DOS commands may not be executed" sound more like a warning than an error. Are you sure, that this is an error message?

Did you try to set the corresponding registry value already?

 HKEY_CURRENT_USER\Software\Microsoft\Command Processor
 REG_DWORD DisableUNCCheck: 1

It is easy to let batch files run in an UNC path:

pushd \\server\folder
... your batch
popd

What a pitty, that old Matlab versions do not consider this.

Hye, thank you or your answer. ;)

My message is a real error and unable me to compile my model.

There is no Microsoft problems because I am able to work wih my models with other release for matlab from 2009 to 2014 with the UNC path.

I have to adapt my matlab (before 2007) to accept UNC or for him not to see the UNC. Do you know if there is a way to bypass it? Maybe a matlab function able to create a real time workshop just for the simulating time and go back to the UNC next?

Do a network drive need to have a letter?

Thanks a lot for your answer!
