Opening file in shared mode will allow other applications to continue working with a file, and moreover, to continue making changes to it.
After you open a file in a shared mode, you may update it in Hex Editor Neo and in any other application.
Working with a file opened in shared mode in Hex Editor Neo is exactly the same as working with any other type of document. The only difference is that Hex Editor Neo displays an overlay warning icon on top of file's icon in its user interface, reminding you that the file has actually been opened in shared mode.
When the file is updated in another application, Hex Editor Neo automatically detects the change and displays a Shared File Conflict Dialog. It gives you options to discard or apply your changes, to discard and apply other application's changes, or both at the same time. It also allows you to close the file if you do not need it anymore.
This dialog is displayed only if Hex Editor Neo is a foreground application. If it is not, it flashes its icon on the task bar and its application window frame until you bring it to the front.
Hex Editor Neo supports opening files in shared mode on any Windows operating system it supports (Windows 2000 or later), any file system (FAT, FAT32, NTFS, ExtFS), and any kind of storage media (local hard disks, network shares, removeable devices).
As opening a file in a shared mode is almost equivalent to copying a file, Hex Editor Neo warns you if you instruct it to open a file which is too large. On Windows Vista or later it uses the disk system rating to guess the maximum supported size, on previous systems it limits the size to nearly 15 MB.
If the size of a file opened in shared mode exceeds the limit, a warning is displayed. You may still continue opening in shared mode if you agree to wait or instead open a file in normal, locked mode.
