Guys, I noticed on my RDS servers (we are using roaming profiles) thats ome of the profiles are quite large. After some investigation i notice the following; there are numerous thumbcachexxx.db files at the following location: AppData\Local\Microsoft\Windows\Explorer These files can be several hundred Mb at times. I'm thinking of excluding them from the romaing profile. Any negative effect of doing this?

Hi Shocko, You can delete the db file. But it will use intensive CPU processing again when the user opens a folder which has lots of images. If you are ok with that you can remove the db files from the profiles. Windows stores thumbnails of graphics files, and certain document and movie files, in the Thumbnail Cache file, including the following formats: JPEG, BMP, GIF, PNG, TIFF, AVI, PDF, PPTX, DOCX, HTML and many others. Its purpose is to prevent intensive CPU processing and load times when a folder that contains a large number of files is set to display each file as a thumbnail.

Thanks , I am using XenApp 6.0 with UPM installed so I might just disable the syncing back of these files ot the roaming profile. I might even look at disabling thumbnail view via group policy.

Hi Shocko, Here is the GPO way: Go to "User configuration" -> "Administrative Templates" -> "Windows Components" -> "Windows Explorer" -> Turn off the caching of thumbnails in hidden thumbs.db files. Hope this helps.Regards, Rafic If you found this post helpful, please give it a "Helpful" vote. If it answered your question, remember to mark it as an "Answer".
