can't save files on usb flash drive

Hi experts

I have this exact 64GB PNY flash drive. I bought it at my local best buy.

http://www.bestbuy.com/site/pny-compact-attach-233-64gb-usb-2-0-flash-drive/4896095.p?id=1218575761355&skuId=4896095

I'm using a Windows 7 desktop pc.

For a months it worked fine.

I put various types of files on it like word documents or created various folders on it and image files and other miscellaneous items on it.

But now it won't let me save anything on it. I can read all the files on it.
 It seems like I only have read only capabilities on it now.

For example, before when I right clicked on the drive in the menu that would come up, it would have a menu item that said "New" and then if I clicked that, I could create a new Folder on my flash drive. So it would look like this:

my old menu when I was able to save stuff to my flash drive

But now when I select my flash drive in windows explorer and then right click to try to create a new folder I get this. If you notice the "New" item is completely gone from the menu so I can't create a new folder.

Also if I try to drag or paste files into my flash drive using Windows explorer then I get this message:

Anyone know how I can fix my flash drive so I can delete files from or add files onto it?

Before you format the thumbdrive, look to see if it has a switch of some sort on it - it may be very tiny.  Some of these devices have a lock that prevents accidental writing/erasure.  You may have set it to "read only" mode.

Try this:
Run CMD as Administrator (hit window key, type cmd, right click on cmd.exe in list and click run as administrator).
Type:
diskpart

When the DISKPART> line displays type:
List Disk

All drives will appear with an ID. You should be able to tell by the size of the disk which one is the USB 64gb drive. Let's assume it is disk 1.

Type:
Select disk 1

Type:
Attributes clear readonly

Type:
Exit

Alternative:
Run regedit and locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
See if there is a key called StorageDevicePolicies
Within that may be a Dword called WriteProtect
If that is set to 1, change it to 0.

If that fails copy all contents off the drive and format. You may not be able to format because of the permissions issues. In that case this tool may assist:

To test this I used one of my USB pen drives,  there is two places you can access the USB pen, one is from Computer and from the explorer task panel on the Ieft right click it
I also notice in your screenshot you have shared folder synchronization?
 explorer usbshared folder syncI dare say that is your problem
please explain how you and what you used to sync the usb with your hdd folders?
Create a new txt document and save it as "backup.bat".
Sync a file between the PC and a USB drive
How much space is left on the drive?
