Hello All,

Firstly, thank you for taking the time to read my post.

We have a customer who uses DraftSight on a number of laptops that have Microsoft Windows Sync Center switched on, in order to work on their drawings when out of the office. This works fine when they leave the office, work on a drawing "offline", come back and it syncs perfectly fine.

However, when the users are in the office and are "online" there is an issue, the user will open a drawing, work on said drawing and save it. When they press save the user believes it to have been saved without issue, however, if somebody else was to navigate to the server location of that file all they would find is filename.dwg.tmp and the file is 0mb in size.

Interestingly, if the first user then right clicks on the file that they just saved and forces it to synchronise, they get a warning in the Sync Center advising that there is a conflict for that file. The conflict says something along the lines of 'The file has been deleted in one location and updated in another' if the user selects to continue the sync the file goes back to its normal location for everyone to use without a problem, until the next time somebody edits the file whilst "online". However the old filename.dwg.tmp stays and has to be deleted manually.

There is a work around to this issue and that is to force the folder into offline mode whilst the user works on a drawing and once finished bring the folder back online in order for it to synchronise or the user can navigate to the UNC path of the folder after working on the file and copy and paste the file as they see it. Neither of which are really adequate.

I have read that turning Transparent Caching 'ON' on the machine is suppose to help, however I have found that after switching this on and restarting the computer it works without issue for the first file edited after that the issue continues. Thinking about this now, I don't remember testing restarting the computer without turning Transparent Caching 'ON', so it may be the restart that causes the first file to work without a problem.

All computers effected are Windows 7, we do not have any other operating system within the company to test if it is solely Windows 7 effected.

Reading up on this issue, it appears that it did not occur in Windows XP (the articles I have read refer to AutoCAD, I don't know if this is similar or not to DraftSight)

I hope this provides enough information and is coherent for someone to attempt to assist me with this problem. If you require any more information, please and and I will do my best to provide it.

Thank you.
