PDF files getting locked while being in Windows Preview Pane

[Bandusiri]

Hi,
In our application, we read files in binary in order to upload them through HTTP to our server from client machine. When a PDF file being reviewed in Windows (7) Explorer preview pane then our application becomes unable to access the file as the file is locked by Preview pane. Following is the IOException we end up with

The process cannot access the file <file path + name> because it is being used by another process.

This situation take places only on PDF files, which, we believe, can be fixed either from Windows or Adobe side.

Thank You,

Perhaps a running app or a context menu entry is locking the file:
Try:
- a clean startup - http://www.sevenforums.com/tutorial...ation-conflicts-performing-clean-startup.html
- Get CCleaner - Tools - Startup - Context menu - save to text (or screenshot) to later see what was enabled, then disable all
- See if LockHunter is a free 64/32 bit tool to delete files blocked by any processes shows anything
