Automatically Move Photos to Folders Based on Exif Date

If you want to automatically move and sort your photos to directories based on the specific date the photo was taken, I suggest you to try a free program called PhotoMove.

Simply choose the directory where your photos are saved, choose the directory under which you want the date sorted files to go and then click on the ‘Find Photos’ Button.

PhotoMove is based on the Perl library ExifTool, using which you can either move or copy your photos to date based subdirectories.

Wait for it to finish scanning and the program will show the number of files found and number of photos that has a valid EXIF creation dates. Then click on either ‘Copy Image Files’ or ‘Move Image Files’.

By the way PhotoMove operates on all files with embedded Exif data, not necessarily picture files.

So if the source folder contain other files that uses Exif to store dates such as Microsoft Excel files (.xls) and Adobe Acrobat PDF files (.pdf), these will get moved or copied as well.

So pay attention to what directories you pick to move or copy files from.

For Command Line users I recommend you the ExifTool by Phil Harvey

How to Dismantle and Destroy a Hard Drive

Hard Disk DriveThere are a ton of reasons why you might want to physically destroy a hard drive rather than use disk wiping software:

higher confidence that the data is destroyed, a recourse if your drive has failed and no longer accessible, and sheer fun.

If the thermite method and other extreme physical disposal methods aren't for you, dismantling the drive to get to the platters is an alternative method.

The main process involves removing the screws around the outside of the drive, pulling out the screws holding the electronics, and then popping the cover off.

After removing the magnets, you can get to the platters, the heart of your hard drive.

First run the magnets over the platters to degauss them. Because that's not a guarantee that the data is unrecoverable, you should then physically destroy the platters, bend them or break them with a hammer or saw them into pieces.

And that will be the end of those discs and the data on them.

The video below shows how Google use a disk crushers and the destruction of old hard drives to prevent leakage of customer data.
