I kept running into the same problem you're experiencing: somehow nested drive+path+filename exceeded Windows' limit for quite a few files, and each one would kill the CD burn.Ī quick work-around to rapidly find and correct the 100 or so path length problems (as it turned out) was to cmd, dir >temp.txt, import the temp.txt directories into Excel, use formulas to append the appropriate directory onto each filename, and length test the resultant string.

In the current environment, it's sometimes difficult to know how to weigh risks vs benefit for these sorts of applications.īefore they wipe my XP machine for a clean install of Windows 7, I decided to attempt a DVD-R-DL-based backup (DVD because USB and flash devices are disabled). Many Spiceheads have probably experienced the challenges that un-blessed utilities could possibly bring into an organization's network. In our environment, users are unable to introduce these sorts of utilities. We use the local drives because local access is about 20x faster than network access.
I have never failed to find what I need when searching the shared drive, but one always wonders, can you be absolutely sure that an xcopy based back-up to the network is really reliable? I xcopy my local Windows XP hard drive to the network drive weekly using xcopy with the /D switch. In my organization, while IT manages networked drive backups, local drive backups are the user responsibility. I was about to write up something simple, but found something that looks fairly complete from a resource I use frequently: You can use vbscript objFile.Path and use string manipulations to get the path length. This is why its common for this on shared drives, the limitation is in the application display, not the file system itself.
Its easy to do, create a path close to 256 characters, then share it. I used to create long paths to test management, monitoring and security applications. Some interfaces in Windows still use the standard API and will limit you to 256 character paths, but you can bypass this using \\?\c:\. Most current application, including Unitrends, no longer have issues with long path names. Applications that use unicode api can extend the path length to 32,767 characters ( (v=vs.85).aspx).
The Windows path length only refers to apps using some of the api set.
