Did you know
Microsoft Windows™ Explorer will fail to copy files under certain conditions? Be
sure all your back-up files are copied with confidence.
The most common way to get the path too long error is to have a too many sub-directories. For example the path below has 20 sub-directories! This is known a as deep directory and is very common in many work place shared drives, downloads and files shared on other operating systems (Max\Linux). The other common way is a filename is just too long.
Coping this path in Windows Explorer will fail.
Path Too Long Auto Fixer automatically fixes hundreds of deep directories and filenames so you don't have to .
Now you can copy and sync your hundreds of files to the cloud, with out error.
Don't miss a file, on your USB backups or to the cloud.
Never miss an Online Backup again

OneDrive, GDrive and Dropbox, etc all enforce the the 260 character limit. You may not even see the errors if you don't check the logs, which most users do not.

File Server Migration Mitigation
With the imminent end of life support for Windows Server 2012 R2, file server migrations maybe part of your upgrade plan to Windows Server 2022.
However, file server migrations with file names and paths that are too long will still fail. Moreover, the Storage Migration Service will fail to the Azure cloud.
And note, the new Windows 2019/Windows 10 Path Too Long setting is not fully integrated into the entire system, so CMD.exe and Windows Explorer will not copy paths that are too long.

SharePoint File Share Migration
Copy files now to target username subdirectories from a SharePoint file share with new preserve target path option (see version 5.1 below). Move files over 15Gb and make sure they fit under the 260 max path limits. Furthermore, you can beautify names using a corporate glossary.

Path Too Long Auto Fixer rocks because can copy thousands of files to a new directory in seconds.
Release V5.1 Improvements
- Do not shrink specified portion of target path. This prevents the target path from being part of the shortening process. This particularly helps with SharePoint migrations.
- Generate command line equivalent for results that are copied or Excel file download of found results.
- Create Date Added create date of the source path to the results window. You can sort now by create date. This will transmit cut'n paste from results windows or when you download Excel of all results. Moreover, the command line now gets two new options: sort by create date "datesort" and "nosort". Nosort skips sorting at all.
Release V5.0 Improvements
- Sub-path replace option will search and replace words in each sub-dir path as split by Delim option. Replacement occurs for the entire sub-path/directory. There are no word boundaries.
- Global replace option will search and replace words/characters in the entire path, a global search and replace. Replacement occurs on the entire path. There are no word boundaries.
- Consolidation, is a feature that means successively selected shortened sub-directories that resolve to same name are allowed. Default, is OFF, to keep all directories names unique after shortening. In worst case scenario, this requires a hash sub-directory name to be used. Default is 0 or false.
- Modified blacklist word file to remove words in each sub-dir path as split by Delim option. Replacement now occurs for matching whole words only, not within a word.
- Modified global blacklist word file to remove words/characters in the entire path, a global search and replace. Replacement now occurs for matching whole words only, not within a word.
- Better command line help for ptlautofixer.exe!
- Improved Excel output format
Release V4.9 Improvements
- Added final fixed paths .CSV file
- Converted .TSV to .CSV files for Found Paths Grid Export
Release V4.8 Improvements
- Added adjustable setting Max Path Length [Range 16-260]
- Added adjustable sub-directory length [Range 1-247]
- Preserve File Name Hard Cut - just cut the filename, no shortening methods will be applied.
Release V4.6 Improvements
- Excel dump of found paths and compressed paths
- Tagging OneDrive files
- Better Unicode coverage for delimeter types
Release V4.5 Improvements
- One button FIX
- User interface is more responsive and user friendly (more warnings)
- Added new filename search filters such as searching files with no extension "*." and matches repeating '?' is supported. IE Search for extension of length 3 is "*.???"
- New delimiters. Delimiters are used to split each sub-dir path into words. Delimiters are combinations of Unicode Spaces, Hyphens/Dashes, Underscores and Punctuation characters.
- Added empty source directories detection and deletion option.
- Added media file detection in advanced options
- Collision detection, if generated shortened name happens to result in the same previous generated short name, this will rename it to avoid collisions.
- Fix button produces a full transaction log (C:\Users\{Username}\FixLongPaths_{timestamp}.log) so you can track file changes.
- Full Unicode support for paths and delimiters.
- Control characters are removed from paths. All Unicode right-to-left characters (except U+061C in case you need this functionality) are removed. Right-to-left characters are used in malware attacks.
