The sample application when mapping a remote network share can't save the excel file correctly.
I get or a corrupt file or an error about sharing violation.

MS states that this can be caused due to the delay of the network, but if I open the same file over a network share (without cbfs in between) it works fine.

So I think the extra delay due to cbfs is causing excel to fail saving large files.

Is there a way to optimize/speed this up? Timeout parameters? Anyone seen this issue with cbfs before?

Did you try modifying Mapper sample to share the disk and testing Excel then? I think MS statement is false. Every software is designed to wait seconds (at least) before failing, and CBFS doesn't add so large slowdown (a second is really large amount of time in this case).

Sincerely yours

I have checked it. The problem is in the sample program. We will correct it shortly and give you a corrected sample.

*small* bump to get some attention, as I'm kinda clueless if it's a bug I should be fixing or not? (is it in the library or in the sample?) if it's in the sample I should be able to debug it myself, but I'm clueless about where it goes wrong.

The problem was more complicated then I thought. But we have found a workaround. So it will be work correctly with the CallbackFS v2.0 which we're going to release shortly.
For files that are located remotely the network type of virtual storage (it's new type of storage in the version 2.0) should be used. Excel (and other Microsoft Office programs too) works with files that are placed remotely in other way then if they are located locally, and this way is safe for working via network.

Please wait for the new release.

We have released the v2.0. You can try it. Use the new method AddNetworkMountingPoint for creating mount points.

I'm trying to do this.
I get the following error:
The filename, directory name, or volume label syntax is incorrect

I call the function like this:
mCbFs.AddNetworkMountingPoint("Z:", null, false);

Is this wrong?
