If you're looking for your company file but can't find it, look in the folder where QuickBooks normally saves company files:
Windows 7 and Windows Vista: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files
Windows XP: C:\Documents and Settings\All Users\(Shared) Documents\Intuit\QuickBooks\Company Files
Note: Windows XP users see the folder as "Shared Documents" when browsing (clicking folders), but QuickBooks and Windows display the folder only as "Documents" in paths and addresses.
Find a file in Windows 7 or Windows Vista
Click the Start button and click Search.
Enter the name of the file you're searching for.
If you don't remember the entire filename, try entering part of the filename.
If you only know the filename extension, substitute an asterisk (*) for the filename and include the extension. For example, enter *.qbw to search
for QuickBooks company files or *.doc to search for Microsoft Word documents.
When your search results appear, note the path listed in the Folder column. This is the file's location.
Microsoft Windows XP
Click the Start button and click Search (and then click For Files or Folders if using the Classic interface). The Search Results window opens.
Click All files and folders in the What do you want to search for? section.
In the All or part of the file name field, enter the name of the file you're looking for.
If you don't remember the entire filename, try entering the part you do remember.
If you only know the file's extension, use an asterisk as a "wildcard" for the filename. For example, enter *.qbw to search for QuickBooks company files or *.doc to search for Microsoft Word documents.
Click the Look in drop-down arrow and choose the combination of drive name, drive letter, and folder to search on.
Search results display on the right side of the Search Results window. The file's location appears in the In Folder column.
