I thought I share a little EnScript I wrote which deals with long file path export issues. The script I wrote basically does the following:

This EnScript plug-in is used to identify and export entries which would exceed the path depths limitations of 245 characters during a normal export. The script will loop through entries that are blue-checked and exports entries which exceed the above limit based on the FullPath column and the specified export path.

The script will export entries that exceed the 245 character limit. Once exported it will also “uncheck” them. This should leave you with items you can safely export using the native EnCase Copy Folder… function.

The script will create a subdirectory called “pathdepth” inside the user specified export folder and export data using the Logical Size of an entry. In addition a log file is created which contains the reference to the original entry details.

Since the script generates a flat export, it renames the files with a prefix to guarantee uniqueness. This prefix is actually the MFT record number on NTFS volumes (File Identifier).

Please report any bugs or suggestions to EnScript Support

ver 1.0.31 : 22 September 2009
+ (fixed) total byte size of selected files keeps increasing if going back and forth with new destination path
+ (fixed) split file type extension into own column in export log
+ (fixed) exclude case name in path upon export
+ (fixed) remove CaseName from path calculations
+ (fixed) add original file name to export log
+ (fixed) uniform export format: with MFT FileIdentifier available (file.ext_id.ext), without MFT FileIdentifier availabe (file.ext_hash.ext)

The EnScript can be downloaded here: Long File Path Export (32.93 KB, 180 downloads), version: 1.0.31 (updated 09/22/09) (Requires EnCase 6.11.2)

ver 1.0.9 : 10 October 2008
+ added MD5 hash value to the exported file name if no MFT file identifier is available.
File Identifier is only available if the MFT is within the evidence file. In case of a LEF
that doesn’t have the MFT, it shows a zero.
+ added check if entry is folder. Folders are not considered for export.

This script was written and tested in EnCase v6.11.2. Please keep in mind that his is the first (beta) version.
