What is a "CAH file? "Queue.cah" just showed up in Sony Ericsson Archive folder yesterday. When I look under "Properties," it says it opens with Windows Shell.dll and is 67 kb. Likewise "DBK File (.dbk)," this one at 13 MB. The SE archive folder is part of my cell phone's PC software suite.

What are CAH Files?

There's not much information about CAH files on the Web other than a few forum posts. Based on those postings, CAH files appear to be related to text messages.

Opening CAH Files

As there's little solid information on CAH files in general, it's tough to say how to open them. From the sounds of it, these files are likely accessed via the Sony Ericsson PC Suite software and not meant to be opened directly.

What are DBK Files?

Sony Ericsson PC Suite uses DBK files as backup files. These files are usually compressed files containing backup information from your phone such as your contact list and other phone information. DBK files are also used as dBase database backup files.

Opening DBK Files

DBK files are often compressed files. This means that they must first be decompressed before you can view the contents. Generally speaking, you can rename the .dbk file to .zip and then use WinZip or a similar utility to unzip the files. However, if you're using the Sony Ericsson PC Suite software, this isn't necessary. If you must restore the phone information via the DBK file, you'll use the PC Suite's Backup Manager to do so. Go to Start> Programs > Sony Ericsson > Sony Ericsson PC Suite for Smartphones > Backup Manager. Choose the Restore feature and follow the prompts to restore the data from your backup.

Both the CAH and DBK files appear to be legitimate files used by your Sony Ericsson phone and its software suite.
