Volumes

Volumes are a key component of a Laserfiche repository. They store images, text, and electronic files in a hierarchical folder structure. The folder structure for a physical volume consists of two folder trees that branch off the volume's root folder. The volume's root folder is the folder designated as the fixed or removable path. If you have designated both a fixed and removable path, each path will only store the type of files that have been assigned to it. In the sample folder structure (shown below on the left), the volume's root folder is labeled "DEFAULT."

If volume rollover has been enabled, a logical volume will contain a set of physical volumes stored directly under the logical volume's root folder, which is the folder designated as the fixed or removable path. If you have designated both a fixed and removable path, physical volumes will be created in each path that will only store the type of files that have been assigned to it, and a folder will be created for each physical volume. This folder is named after the appropriate logical volume followed by a sequential number. In the sample folder structure (shown below on the right), those folders have been labeled DEFAULT1, DEFAULT2, DEFAULT3, DEFAULT4, and DEFAULT5.

Each branch off the volume's root folder contains three-level-deep folder trees. In the sample folder structures (shown above), the first branch is labeled 00 and contains the data (image and/or text files) for each document assigned to the volume. The second branch is labeled e00 and contains the electronic files for all electronic documents assigned to the volume.

Each image or text page in a volume is assigned a unique file name (based on an internal ID), which determines its location in the volume folder structure. Images are stored in TIFF Group IV and TIFF JPEG format. Text pages are stored as ASCII text files. Electronic files are stored in the same format in which they were imported. All of these files can be viewed by any application that supports the corresponding file format. The volume folders also contain .LOC files, which contain word location data, and .LFT files, which contain page thumbnail data.

Tip: You can move both physical and logical volumes to new locations if you want to spread performance over multiple machines or if you are running out of space on a particular hard disk. You will need to physically move the entire volume file in Windows and change the Volume's path string. See the Volumes section for more information on volume management.
