3.7 Notes on Windows 7 and Windows 8 Directory Protections
3.7.1 User Data File Paths
Windows™ 7 and Windows 8 institute a policy which prevents user data from being
written into the Program Files directory/folder. It was common for applications written
for Windows XP (and earlier) to use the Program Files folder to store user data. Teledyne
LeCroy and CATC products used this folder as a default folder for storing trace files, user
option files (default.opt, default.rec), scripts, and so on. The default folder for USB
Protocol Suite was:
x:\Program Files\Lecroy\USB Protocol Suite\…
Windows 7 and Windows 8 make such paths illegal directories for user data. For Windows
7 and Windows 8, files that are accessible by different user accounts must be in the path
x:\Users\Public\…
To preserve the ability of multiple user accounts to access all the Teledyne LeCroy files
that were accessible in Windows XP when using Windows 7 and Windows 8, files that
were in the Program Files path in Windows XP are now in:
x:\Users\Public\Documents\Lecroy\USB Protocol Suite\…
In some cases, such as paths stored in the Recording Options .rec file, the application
silently changes this path, so that the Windows 7 and Windows 8 operating systems will
accept it as valid.
USB Protocol Suite on Windows XP still uses the Program Files directory. However, if a
Recording Options file that was created on a Windows 7 system is used on a Windows XP
system, trace files will be probably be recorded to a new Windows XP directory called
x:\Users\Public\Documents\Lecroy\USB Protocol Suite\…
This is a legitimate path on a Windows XP system, so there are no conflicts with the
operating system.
3.8 Notes on Windows Sleep and Hibernation Features
Hibernate and Sleep modes are not supported during acquisition, uploading or decoding.
The software is designed to not allow the system to go to low power modes. If the user
forces the system to go to these modes, the result for USB Protocol Suite is unpredictable,
and corrupt files may result.
