How to detect if a file is being used?

[richardander]

Hi,

My application is going to load a file and modify. Before loading the file, is there anyway to find out if the file is being opened by another application?

thank you!

Only if that other application has locked it (works in some file systems) or if you device a locking scheme (usually a hidden file)

Does QT provide any function to check it?

You can use QtLockedFile (http://www.qtsoftware.com/products/appdev/add-on-products/catalog/4/Utilities/qtlockedfile)
