Re: Error while saving a file from application to Guac virtual drive

[Antony Awaida <an...@apporto.com>]

Hi again Guac team:

We have a solution for the download problem above - we have added a button
that will initiate the download process for a specific folder (it is not
initiated automatically when the user saves in that folder which was the
problem above).

Now, our users keep complaining about the upload- despite ample
documentation on the correct process of moving files (pesky users!). They
upload a .mpp file and when they try to open it using MS Project they get
the error described above.

We are considering the following approach:

When uploading, what if we watch if we can grab a handle on the uploaded
file on the Unix side and if yes, this means the upload is complete and we
can move it to a more MS Project friendly location (e.g Desktop).

Thoughts?

Thanks!
