Singular file finder

[keithrj]

Again, I use IMatch and have written a procedure that lists all files that do NOT appear on the target drive (or DVD/CD). This tells me which files I need to backup.

If you want to use IMatch then let me know and I will give you the procedure to do this.

Many thanks, Keith,

For what it's worth, I figured out how to check for singletons using portable freeware: one of many excellent and incredibly small Nir Sofer's applications - HashMyFiles (the Total Commander almost worked, but I couldn't get the last step to work). Basically, HashMyFiles creates the list of e.g. MD5 hashes across directories (I can even use wildcards to limit it to the CR2 files only). The list also has an 'Identical' field/column which brands the same hashes with the same integer (or leaves it blank for singletons). The list can be sorted by this column, so that the singletons are separated. So if I hash both the source drive and the destination drive on the same list, it's easy to find out the singletons.

HashMyFiles sounds useful, I must take a look. Thanks for the update!
