For example, to get a FolderItem for Microsoft Word in the Program Files folder on the boot drive, you can use the following line of code (The line continuation keyword, _, is used to split the line into two printed lines). You can get the number of drives with the DriveCount function. Passing DriveAt 0 will return the boot drive. Pass it a number that indicates the desired volume. The DriveAt function returns a reference to any drive on the user's computer/device. Use the DriveAt function, the Parent property of the FolderItem class, and the Child method of the FolderItem class to specify pathnames. The proper way is to first collect all items in a loop into an array, then walk the array and delete the items accordingly. Do not be tempted to walk the directory items backwards (from Count downto 0), even if you see many recommendations for doing so.
To delete items from a folder, follow the above rules as well.Instead, first collect all items into an array of FolderItems, then walk the array items and enter any folders you encounter. If you want to recurse into subfolders, do not go depth-first.If you iterate backward, it may get very slow if the directory contains a few hundred or even more items. Always iterate forward, starting at index 0 and ending with the index that matches the folder's Count.If you walk directory contents, follow these rules: Xojo Cloud's file system is case sensitive.Īvoid invoking functions such as Count, Child and IgnoreAlias multiple times for the same target because these functions are time-intensive (especially on macOS). If you do not, you may find that files cannot be found when your app is running on Linux. This means that if you are creating apps to deploy on Linux (including web apps deployed to Linux servers), you need to ensure that your filenames correctly match case. PropertiesĬonstructor(path as String, pathMode as FolderItem.PathModes, followAlias as Boolean = true)īe aware that file systems on macOS and Windows are generally not case-sensitive, while file systems on Linux usually are case-sensitive. Common ways to create FolderItems are by using the Constructor, SpecialFolder along with the FolderItem.Child method or using the various FolderItem shared methods for selecting files. But the company managed to stay in business all this time and isnt looking to end it any time soon. The dev community is fairly small, though. Its strength lies in its ability to make native looking and behaving apps for many platforms, mainly OS X but also Win and even Linux. FolderItem class objects represent files, applications, or folders. Xojo has been around since the late 1990s, then named RealBasic.
