Samsung's next XCover rugged phone may add built-in RFID scanning

Photo: Wikimedia Commons / CC0 Samsung's Galaxy XCover line has always been the tough phone for people who work with their hands — construction crews, warehouse teams, field technicians. Now, a new chipset and trademark filing hint that the next XCover could gain an unusual addition: built-in RFID or barcode-style scanning, turning the phone into a data-collection tool as well as a rugged handset. What the hints suggest Rugged phones already stand apart with reinforced frames, glove-friendly touchscreens and batteries you can swap in the field. Adding a scanner would push the XCover further into professional territory. Warehouse workers scan inventory, delivery drivers log packages, and maintenance crews check asset tags — all tasks that currently need a separate handheld scanner. A phone that does both jobs would cut the kit workers carry and let scan data flow straight into the company's apps, without a sync step at the end of the shift. Why it matters for field work...

Make Undeletable, Unrenamable Folders

Have you ever wondered how you can make a folder which neither can be deleted nor be renamed. Well, if you have, then you have come to the right place. With this trick, you will be able to create folders in Windows which cannot be renamed or deleted.

Basic Concept
The basic concept behind this trick is the use of Keywords. Keywords are reserved words in any programming language that cannot be used as names of variables. Windows also uses certain keywords in its programming. Some of them are con, aux, lpt1, lpt2, lpt3, lpt4, lpt5, lpt6, lpt7, lpt8 and lpt9.

Make Undeletable and unrenamable folders

A Test
To test this concept, make a new folder in Windows and try to give it a name same as any keyword mentioned above.

Result
Windows will not rename your folder to any of the keyword given above.

Trick
So the question arises, how can we make a folder with a keyword as its name? The solution to this problem is included in Windows itself. As we know that Windows has evolved from D.O.S.(Disk Operating System), its commands can be used in Windows. You can use D.O.S. Programming in Windows to create a folder with a keyword as its name using the steps given below:-

  1. Click on Start.
  2. Click on Run. Type in "cmd" without quotes.
  3. In the Command Prompt Window that opens, type the name of the drive you wish to create your folder in the format <drive-name>: and press Enter. e.g. If you wish to create the undeletable folder in D drive, type "D:" without the quotes. Note that the folder cannot be created in the root of C: drive (if C: is your system drive).
  4. Type this command- "md con\" or "md lpt1\" without the quotes and press Enter. You can choose any of the keywords given above as the name of your folder.

Now Windows will create an undeletable, unrenamable folder in the drive you entered in Step 3. However, the folder can be renamed to another keyword using Windows Explorer.

Deleting the Folder

Although, it is not possible to manually delete the folder, you can delete the folder by typing "rd con\" or "rd lpt1\" in Step 4 instead of "md con\" or "md lpt1\".

Windows Compatibility: This works on Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 8.1.

Try it yourself to create one such folder which can neither be deleted nor be renamed.
