This software can scan through a series of nested folders to confirm the existence of image files.
If you're looking for an efficient way to verify large numbers of image files, ImageVerifier (IV) may be just what you need. Developed specifically to process high volumes of images, this software can traverse folder hierarchies containing 100,000 images or more with ease. In fact, during one test run, IV ran for an impressive 14 hours!
IV can verify a range of image file types, including TIFFs, JPEGs, PSDs, DNGs, and non-DNG raws (such as NEF and CR2). All structure verification, except for non-DNG raws, is built-in, with DNGs verified using Adobe's DNG SDK directly. JPEGs and TIFFs are verified using built-in libraries, and PSDs are validated using a method designed specifically for IV that follows Adobe documentation for the PSD format. Non-DNG raws are verified by running them through Adobe DNG Converter.
For each verification run, IV offers two kinds of verification: Structure checking and hash checking. Structure checking is performed by reading the actual image data, decompressing as necessary, and can find many errors (although some errors are indistinguishable from image data). All image files undergo structure checking, with the list of extensions for raw files being the same as ImageIngester's.
The real work is done by subprocesses, meaning IV can take advantage of multiple CPU (or multiple core) computers. If you have 4 CPUs, it should be capable of fully loading all 4 at once. For each verification run, you can choose the folders to process, whether to process subfolders or just the top level, what kinds of images to process (TIFF, JPEG, PSD, DNG, and/or non-DNG raw), the maximum number of errors to report, and whether to store the results in a built-in database. You can save the settings in a named job, which functions much like ImageIngester's Preference Sets.
IV also comes with a built-in scheduler, allowing you to schedule jobs to be run once at a specified time, daily at a specified time on specified days (e.g., Tuesdays and Saturdays at 2am), or monthly on a specified day and time (e.g., the 3rd of every month at 5am). The scheduler uses the "cron" facility built into OS X 10.4 and does not have to be running for a scheduled job to run, nor does it keep its own daemon process running.
Overall, ImageVerifier offers a comprehensive solution for verifying large numbers of image files quickly and efficiently.
