Today I was surprised to see 350MB in a single InfoPath FEATURE folder on the below web front end server. Whaaaat?!? I had to blink a few times and even confirmed the size manually in Windows Explorer. Yup, this form was eating up lots of storage. Making matters worse it was on every web front end across the farm. But why? When you deploy an “update” to existing Central Admin InfoPath Form Templates it just adds another subfolder. OK, maybe that’s a neat version history thing to have … or maybe it’s slowly sucking the life out of your storage.
Below we have 960 “updates” deployed to a single XSN with Central Admin and over 300MB of old XSN garbage.
The fix for me was basically to uninstall the whole thing and deploy the XSN anew for the first time. Going forward I plan to avoid the “upgrade” option from Central Admin Manage Form Templates. Better to use the “remove” option then deploy fresh each time.
- Remove from from Central Admin > General > Manage InfoPath Form Templates
- Retract WSP from Central Admin > System Settings > Farm Solutions
- Delete “FT-GUID” folder on each web front end’s 14 hive
- Upload the XSN and start fresh
