When editing documents directly from a network share, many applications, especially from Microsoft and Adobe, expect a hidden folder named ".TemporaryItems" (starting with a period) at the root of the volume. The application uses the .TemporaryItems folder to perform a "safe save" operation -- when saving an updated version of the file, the application first saves it across the network to the .TemporaryItems folder, before replacing the previous file. That way, if the save process is interrupted, the previous version will remain intact. For more details on safe saves, see Apple's knowledgebase: http://support.apple.com/kb/TS3752 and http://support.apple.com/kb/ta23804.
The .TemporaryItems folder should be created on demand, so if no one with proper rights at the root of the share has made that request, it will not be created.
If you encounter errors trying to edit documents on a share, follow these steps:
1. From the server, go to the root of the volume in Windows Explorer. NOTE: With Acronis Access Connect, the volume is as you've defined it in the Acronis Access Connect Administrator. So if you share out a volume with the path D:\Headquarters\Marketing, from the Mac's perspective, the root of the volume would be the Marketing folder, not D:\ or D:\Headquarters.
2. Set Windows Explorer to show hidden files and folders (View --> Options --> View tab --> Show hidden files, folders and drives)
3. Look for a .TemporaryItems folder. If it doesn't exist, you can create it manually from a command prompt on the server, as follows: mkdir .TemporaryItems. Note you won't be able to create it directly in Windows Explorer, though you'll see it there if hidden items are shown.
4. Select the folder, click Properties --> Security and make sure the user in question has full control. In general, anyone saving to the folder will need full control of the .TemporaryItems folder and sub folders in it.
5. Confirm the permissions for a specific user through the Effective Permissions tab (see separate FAQ question)
