FileBack PC Knowledge Base

ERangeError scanning folders

While scanning a source or destination folder, FileBack PC is finding files that have invalid dates.  When FileBack PC was written no check was included within the software for invalid file dates, so when these files are processed it is causing FileBack PC to generate error messages, such as a Range Check Error, or other strange messages.

The behavior of FileBack PC will be fixed in the future.  However, for the time being, we have written a utility that will validate your file system and fix some errors that can occur.  This utility is available for free download:

Click to download the File System Validator.

This program does not come with an installer; extract the contents of the .ZIP file and double-click FSValidator.exe.

This utility will scan for and correct several file system errors:

Condition Can Detect Can Fix
File Modification, Create, or Last Access Date Missing

File Modification, Create, or Last Access Date Invalid
File Modification, Create, or Last Access Date in the Future
Filename contains Unicode Characters *
Filename contains Invisible Characters
Filename contains Invalid Characters
Folder Modification, Create, or Last Access Date Missing  
Folder Modification, Create, or Last Access Date Invalid  
Folder Modification, Create, or Last Access Date in the Future  

* Unicode filenames with associated DOS filenames can be "fixed" for FileBack PC.

To use the software, open it as described above and click the "..." button to select a folder to scan.  Select the scanning options you desire and click the Begin Search button.  Folder scanning should proceed quickly.  Once the folder has been scanned a list of files with problems, if any, will appear.  Click, Shift-Click, or Control-Click the files to fix or delete, and click the "Delete Selected Files" or "Fix Selected Files" button.

You may right-click on a file to view it in Windows Explorer or view its Properties page.

Folders with invalid dates cannot be fixed.  Windows does not have a mechanism in place for manually changing folder dates.  For FileBack PC this will not matter; it does not attempt to process folder dates in any way.
