Another update to one of the most useful tools for the BlackBerry came out today. FileScout has been updated to v1.4.1. If you aren't familiar with this app, you might want to check it out. It allows you to browse through your system files easily and delete any unnecessary files or files you might not want. FileScout gets updated regularly and is available in App World or by visiting the developer's website on your BlackBerry. You can view the changelog here. If you like the app, be sure to drop the developer a donation for his hard work.
You must be using OS v5.0 as this behavior has been documented. From an earlier changelog:
2009/10/10 - FileScout release of 184.108.40.206
This is an update only for OS5.x Users - for other OS Versions this new FileScout Version is not needed at all - that's also the reason why I do not make a big announcement (via the mailing list)
* OS 5.x ONLY: Endless loop for system folder fixed - Unfortunately in OS 5.x it's not possible anymore to access the system folder via the file system API. With this Version FileScout will display an error message when the API does not return any content for a folder. This also means that FileScout can't be used to delete pre-installed files located in the subfolders of 'system' for devices that have installed OS 5.x.
