Dreamweaver CS3 crashes after DST ends

Last week at the office Dreamweaver CS3 kept crashing on me when I was working on PHP files. In the end it crashed almost instantly after I opened a file. Very annoying indeed! Instead of re-installing etc. I did some googleing and found the following issue explained several places including on Adobe’s support pages.


Adobe Dreamweaver CS3 crashes when working with certain PHP or ASP files in Code view or Design view after the clock goes back one hour, when Daylight Savings Time ends. The crashes only occur when selecting certain lines in Code view, or selecting certain objects in Design view. The crashes only occur in files that have PHP or ASP code, intermingled with HTML code. The crashes do not occur in Dreamweaver 8 or earlier (Ref. 229536).


The Dreamweaver CS3 WinFileCache-AD76BB20.dat file has been corrupted by the time change.


  1. If Dreamweaver is open, quit the application.
  2. Delete the WinFileCache-AD76BB20.dat file from the Dreamweaver user configuration folder. Note that on Windows, the Application Data and AppData folders are hidden by default, so verify that your Windows Explorer folder options are set to View Hidden Folders. The location of this file is as follows:
    • Dreamweaver CS3 on Windows Vista:
      C:\Users\[username]\AppData\Roaming\Adobe\Dreamweaver 9\Configuration
    • Dreamweaver CS3 on Windows XP:
      C:\Documents and Settings\[username]\Application Data\Adobe\Dreamweaver 9\Configuration
  3. Restart Dreamweaver.

  1. This is the BEST blog post I have ever read! thank you, thank you, thank you!

    This problem has been doing my head in for weeks and I just put it down as a “quirk” of Dreamweaver, so didn’t look for a solution until it became unbearable!

  2. Excellent advice, everything is back to normal now. thanks very much!

  3. Hi,
    I when to …. C:\Users\[username]\AppData\Roaming\Adobe\Dreamweaver 9\Configuration , but i didnt found any: WinFileCache-AD76BB20.dat , also i looked into te catalogs. Please Help me.
    I got anew PC with vista home edition on.

  4. I’m not to familiar with Vista but maybe you can’t see this file as you haven’t set Vista to show system files. Try as follows:

    1. Click the round blue Start thing in the left corner
    2. Click Control Panel
    3. Click Folder Options
    4. Click the View tab
    5. Click Show hidden files and folders
    6. If you want to see system files as well, unclick Hide protected operating system files (Recommended)
    7. Click OK

    Or visit microsoft.com’s FAQ section.

  5. It happens in DW8 on a PC (hence the “Win” in WinFileCache). It also happened on my co-workers computer–also DW8 onPC.

    Looking for perm fix…..but that maybe to switch to mac, as macs don’t employ a retarded file system (anyone ever hear of having to “defrag” a mac or linux box…yeah didn’t think so).

  6. Wow, this has driven me crazy for days…..then to find out it was something like this. Grrrrr at adobe!

    Thanks Dude this solution is awesome
