When browsing documente library contents from client application, cannot see all files

Question

We are currently running SharePoint 2010 Enterprise in a small environment. On one of my sites, I have a document library with various documents uploaded (docx, xlsx, pdf). I am unable to see all the documents when browsing the library from Word/Excel/Adobe
Acrobat. For example:
- At the root level of the library, I have 5 folders
- In Folder 1, I have 10 PDF files
- If I go into Adobe Acrobat 11, for example, and paste the address of my site in, I can see the library and I can click on it and see the 5 folders.  If I click on Folder 1, there are no PDFs listed.  Even changing File Type to "All Files"
still returns 0 results
Things I have tested:
If I view the library in the browser, I can see the 10 PDFs in Folder 1.  They are not checked out and they are visible to everyone
If I click Library>Open w/ Explorer, I can see all 10 PDFs in Folder 1
If I try using other client applications (Word, Excel, etc..), I cannot see any files in Folder 1, even when I change the File Type to "All Files"
If I click in some of the other Folders in the same library from within a client application, sometimes I can see the files but most times I cannot
What could be causing this?  I do not see any errors in any of the event logs.

Hi Sephiroth,
I think my observation is when you browse from word/Excel/Adobe it is taking your local system credentials and so  not showing files when you access.
local system account means the account which you used to login to the system.
For example,you logged into the system as contosomo\xyz and you are trying to connect to the site using Contosomo\setup account,what my point is though you logged in to the site using the setup account site is taking your xyz account credentials and so it
not showing any files as xyz obviously will not have access.
To confirm this, you can try by giving atleast read access to the local system account (in this case xyz) to the library and then test again whether you are able to see the files or not.
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem.
