Apr 16, 2014 - One of the key features of your SyncPix digital picture frame is the<br />. ability to copy photos from a memory card to the frame's .....

I removed my CF card from the picture frame and plugged it into my computer to see if it might be corrupted. It worked ok so I put it back in the Pic. frame and it worked ok their too ????

Go to My Computer > Removable Drive. Drag and drop pictures there.

Are using a memory card. If yes, than go to "my computer" than click on drive that has memory card. (probably i: drive)
The Music file is probably is mp3. Pictures are DOC

The frame has a light sensor. If it is too dark, the frame turns off the screen. You can change the sensor setting to avoid this problem. Check out the FAQ as following http://smartpartsproducts.com/content/support/faq/news.php?newsid=16

The setup file is on the frame. Connect the frame to your computer w/ the USB cable. Go to MY COMPUTER. Look for your frame as a removable device and open it up. There is a blue icon called "setup." If you click on it, it will start to download to your computer. If you can't find it, you can download from Smartparts website at this link:

Make sure the music is in the correct file format for the frame. Some frames take MP3, others take WMA. If the format that you have is not compatible, you must convert it or the frame will not read it.

Make sure the music that you are trying to download is the correct format. Some frames take MP3, others take WMA.

To remove a picture, connect the frame to your PC via USB. you should see the frame appear as a drive, in my case,
36972 (E:)

open the drive as Explore, you can now see the pictures, and delete what you no longer want.

you can download the software from

1 utf-8 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Once you connected your EX811 to your computer, and get the message “Use PC interface to copy files.” That means you can start copying files. Here are the steps:
Copy pictures, videos, and music between your frame and computer, using your computer's normal file copying tools:

1. Connect the USB cable from the frame to your computer
2. On your computer, open My Computer or Windows Explorer.

The picture frame appears as removable drives—one drive for each connected picture source in the frame, in this order: internal memory, memory cards, and USB devices.

3. Navigate to the pictures you want to copy. Then drag and drop them to the new location.
4. Unplug the USB cable to view your copied pictures.
