To delete files on my iriver E100, do I have to connect to something like Windows Media Player or can I just do it straight from the E100 menu? Everytime I try it gives me the message "can not delete the file in MTP mode". I do NOT have the E100 connected to my PC when I try this. The E100 manual just says to hold down the right arrow button to delete files from File Manager, but I always get the above message and it doesn't delete the file. Thanks!

Greetings - your IRiver E100 only plays certain .avi files and versions of Windows Media (.wmv) files.

To use your media center and MP4 files you would have to obtain converter software that would convert the files to be compatible with your player. Recording TV shows creates files which are incompatible with the E100 as are MP4 files.
For the TV recordings you would have to do as follows:





Forget the mention of IOS device above - you need to do the same step.





You then have to convert them to files that the player can use. I'm told this software works well and is only $9.95 (USD). Take a look HERE. (I have no connection with this company).

For other files (like MP4 files) you just have to use the converter software I mentioned above and don't need the first step I displayed above.

Enjoy your Video.

To delete files from your mp3 player using Windows Media Player 11:

My Directions:

1. Connect your mp3 player to the computer

2. Open Windows Media Player

3. Click on the icon of your Mp3 player on the left-hand side of the Library

4. Click on the Songs, Tracks, or other Music Folder

5. Find a song or songs that you want to delete

6. Left-click the song once to highlight it

7. Press the “Delete” button on your computer’s keyboard

If you want to delete stuff from your E100 while your actually using it then you go to file manager in the menu, find the file you want to delete and then hold the right arrow until it comes up with 'delete file'. If you want to delete it while your on your computer then find the folder of your E100, find the file and just hit the delete key or right click and 'send to trash' or drag the file to the trash.

well i can solve this its very easy there are 3 types of avi files there is just avi format 
there is a divx Which is also an avi file and xvid which is supported by the iriver e100
so yeah you can use this software on

http://www.download.com/YouTube-Downloader/3000-2071_4-10647340.html has the coolest downloading software it converts flv to xvid avi which is supported by the iriver e100

The video files should be in the video folder instead of the music folder - use Windows Explorer to be sure. If they are not showing up, switch the device's mode to MTP mode and see if the video files show up as available for deletion.

Software / Media Transfer The E100 comes packaged with a disc containing iriver plus 3 media player, firmware updater, video converter, and Windows Media Player 11. If you have owned an iriver player, you are familiar with this software with the included iriver media player. This is a standard media player much like any other but has a few features catering to the iriver family of players, such as a firmware updater, ebook txt manager, and video converter. This media player is a bit different from Windows Media Player but still is straightforward and easy to use. If you don’t care for iriver’s media player you can always use any other MTP based media player to manage playlists and load your E100 since also included on the disc is a video converter and firmware updating utility.
If you don’t like to use media players to transfer the E100 will allow you to select either MTP or MSC transfer mode. This means it is drag and drop and also compatible with any OS. Drag and drop will work fine in MTP mode as well, but only if you are using Windows XP SP2 or Vista.

and the difference between e10 / e100 your guess is just as good as mine
