How Can I Safely Retrieve Files from a Directory, Ignoring Access-Restricted Subdirectories?

Use Directory.getFiles () to retrieve files security, ignore access to the restricted sub -directory

When using the Directory.getFiles () method to perform the file system operation, encountering the directory that cannot be accessed may cause accidental abnormalities and interrupt the process. This article explores a solution that allows you to ignore these protected folders and continue to retrieve accessable files from the specified directory.

The code fragments provided are attempt to get the list of files in the selected directory and the sub -directory. However, the presence of a file that lacks access permissions may trigger unauthorizedAccessAccessException abnormalities, thereby stopping the process.

In order to overcome this problem, a alternative method was introduced:

Manual subdirectory iteration:
• The code is not using Directory.Getfiles () AllDirectories options, but the calendar directory one by one. For each subdirectory, it tries to retrieve files while handling any exceptions elegantly.
The modified code uses "FileAction" to process a single file. It iterates a given folder to call "FileAction" for each accessable file. For sub -directors, it tries to apply the same process recursively. If any sub -directory causes abnormalities, the exception will be captured and the process will continue.

By implementing this strategy, the code can effectively ignore the irreplaceable folders to ensure that the accessable files are obtained without any interruption.
