Ron has a Samsung Galaxy Note 4 and he's been emailing himself mp3s he makes in the recording studio. The phone holds onto the file for about a day, and then it disappears. Leo says it sounds like the download goes to his cache, which gets cleared out. Leo recommends using an app that will enable him to move it once he downloads it. Samsung's File Manager app will let him see that folder.
Paul has updated to Android Kit Kat 4.4.2 on his tablet, but now he can't see any files that he's downloaded. Leo says it's likely that Paul is just looking in the wrong place and that he's actually downloaded his files and just can't see them. There are a few download files in Android, one for apps and one on your SD card. That's why Android has gotten rid of the SD card option. It's confusing. A third party file manager like Astro File Manager or ES File Manager will show you what you're looking for.
Mark has a huge hard drive with over 300,000 songs and videos. Is there any software that can go through the list and remove any corrupted or damaged files automatically? Leo says that Media Monkey has some great tagging and music management features. It's free to try. Mark could have it reorganize his folders, but if there's a corrupted file, there's no real way to know it unless he plays it.
Emilio is looking for a good file management utility that has good accessibility features, chiefly via speech. He wants to be able to sort and make documents that are easily searchable. Evernote doesn't do it. Leo says they should.
Glen has several USB thumb drives with files on them. His computer hard drive died, so he replaced it. But now he can't write to the thumbdrives anymore. Leo says that's because technically, they're "owned by another." Windows sees that new account as a new user. He can take ownership of them, but it's not trivial. HowtoGeek has an explanation of how he can do this.
Tom has a computer running XP and he's having issues with the accuracy of the number of files in his folders. Leo says that it sounds like the file index is corrupted. He can rebuild the index in the control panel. Windows XP's copy utility is broken also, so Microsoft's answer to that was to offer a separate file copier called "Robocopy." He could also try refreshing the folder in the folder menu. Otherwise it's probably time to upgrade to Windows 7. He should make sure to backup his data too.
