You should refer to the Release Notes that is included in each version of the Repository module (or any core module) to understand any changes.

Here's is a section of the 3.01.14 release notes that references the 'All Files' feature

=======================================================================
03.01.14 RC1 Build 16515
Released 10.31.2007
=======================================================================

-- Implemented new logic for the "All Files" category. There is a new
   setting in the module settings. A checkbox named "Show All Files". If
   checked, then in the Categories dropdown an entry for 'All items'
   will be inserted at the top of the list. Selecting 'All items' from
   the categories dropdown will display ALL items regardless of their
   category membership.

-- The logic for the new 'All items' filter was extended to the 
   Dashboard module. If the repository module setting for 'Show All
   Items' is checked, AND you are using one of the category modes, then
   an 'All items' hyperlink will be displayed along with the categories

-- With the above changes, your existing "ALL Files" category is now
   just a simple category, you can delete or rename it to something
   else. The logic to enforce the first category has been removed from 
   the upload/edit process. You can now upload an item and not associate
   it with any categories at all if you do not check any. You would then
   only see the item if you selected the new 'All items' filter.

-- The text for 'All items' in both the repository module and the
   dashboard module is localized, you can change the text by editing
   the key in the Localresources file for the module.

-- Fixed the localization issue regarding the "All Items" text in the
   repository module's header.html template and the dashboard
   template. You can now change the text for the "All Items" category
   by editing the corresponding resource file

=======================================================================
03.01.14 RC3 Build 15506
Released 10.31.2007
=======================================================================

-- Now that you can delete the existing "ALL" category, I fixed some
   minor issues to make sure your repository module will work properly
   IF you have a module with NO categories defined at all. I also
   fixed some minor issues with the Upload/Edit form and the Dashboard
   when there are no categories defined for a module.

=======================================================================
03.01.14 RC6 Build 20678
Released 12.10.2007
=======================================================================

-- Fixed issue where only the first category of files would be displayed
   if you enabled 'All files'. Now, if you have 'All files' enabled
   when the user first goes to the page, the 'All files' category
   will display and all files will be displayed. Once the user selects
   a category, a cookie is written to the user's machine and the
   next time they come to the page, the last category they viewed
   will be the default category that is displayed. Clicking on 
   categories will now always display the proper files, including
   selecting the 'All files' category.

 hi steve,

thanks for release notes. I gone through that content. i have tried the all the solutions which are mentioned in that release notes.

but my problem is exist. My Problem solves when  i go to any repository instance and update the applying template as 'Default' or 'filelist' then go to repository module and select 'All Items' category then files are listed in the repository which i uploaded previously. Then revert my template as before. Now repository listed out my uploaded documents/files. 

if i not select the 'All Items' category with applying 'Default' or 'filelist' template , then my recently uploaded files are not listed out.

Have you any idea about it? Is there any cookie saved when we select 'All Items' category or anything else.

Please suggest me on this point , i want solution ASAP.

Thanks for attention.
