As part of the data recovery process, the directories options allow users to store files in locations suitable for their own computer. By default, all working data is stored under a directory c:\cnwdata, but these can be moved to any other logical location or drive.
The image directory is where a file image will be saved. The drive for this directory must have enough space to save a complete disk image. One point to take care of is related to compressed NTFS drives. From experience, a compressed NTFS driv e has a limit on the maximum file size that may be saved. The maximum is dependant on the size of the CPU memory, and as arough guide, a 1GB system will have problems with files of about 60GB or greater, The symptom is normally a 'defered write error'
Details of every file recovered is logged. The logs can become fairly large, so adequate space should be allowed. However, the logs will compress well, so it is a good directory to apply NTFS compression to. Under recovery options it is possible to limit the length of time logs are stored, which again may help conserve disk space.
Scan offsets directory
For some FAT disks it is possible to adjust for areas of the disk that are not in the correct logical location. This is typically due to the hard drive mapping table being corrupted. The offsets are stored in a file in the scan offsets directory
Log Export Directory
Log files may be exported into a CSV format. These files are stored in the directory specified in this section
File Filter Directory
File filter routines are stored as short data files. This is the directory location of where data files are stored.
The search strings directory is where tables of search parameters are stored
Temporary files directory
The temporary directory is used for some processes that require temporary files. These files may be deleted, and at times the program will automatically purge the directory. Do not be tempted to store any user data in this directory.
