Command to compare folders
There are two main options for the File Compare tool that you can use.
#Command to compare folders how to#
Like every tool in command prompt, you will need to know how to enter your commands with the proper syntax. This is the Pathname parameter in which you will state the location of your files. There is only one parameter you will need to specify, but you will need to enter two instances of it.
The default, if you do not specify a number is 100 lines of mismatched text. /LB n – Replace the “n” with a number to limit the amount of consecutive different lines that FC will read before it will abort./N – This switch can only be used with ASCII but it will show all the corresponding line numbers./L – This will compare your files as ASCII text./U – Use this switch to compare files as Unicode text files./A – This switch will make FC show only the first and last lines for each group of differences./C – If you need to do a case insensitive comparison, use this switch./B – This switch will perform a binary comparison.I know that leo has BC3 installed on his system too, although DO10 does have the synchronizer (which includes a Comparer). But synchronizing with BC3 is not all automatic BC3 is mainly a comparison tool. Then i opened BC3 and it read the 2 folders and did the comparison rather fast. Would you admit/confirm that the DO10 synchronizer is indeed inferior (in performance and stability) to third-party products such as the popular Beyond Compare 3 (BC3)? reading works (takes long!), comparison works (takes long too!), and then it takes "even longer" until the copying process (step1. I installed Dopus 9.5.6.0 and there's no such error message. before the comparison (in the RAM memory) takes place.
With Dopus 10.0.0.2 beta and synchronizing 150.000+ files (in ~10.000 folders) from local E:\ with external hdd G:, i get the above error during the reading of G:, i.e. however i get the subjective feeling that it takes very long before it actually does the file operations (copy, delete). It is very clear in what it does and what options are at hand. I like the synchronize (which comes with a Comparer) tool a lot. (i am not sure if this is the right place to post.
#Command to compare folders plus#
What I'd really like to see someday to address this (in addition to the multi drive bug fix) is 2 things:Ī) an extension to the internal command set so that we could directly invoke the dupe file search from a toolbar button and run it against series of selected folders or against the current folders in a dual pane lister.ī) an extension to the existing dupe file finder utility so that we could specify multiple folders in a similar UI pattern to what GP offers to add additional filters to a filtered operation - ie: some plus and minus buttons to reveal or hide additional 'Search for duplicate files in:' fields. and it 'would' work if this little bug in the dupe search were fixed.
So, what I would have suggested if the multiple logical drive selection worked right is to use SUBST to alias each folder as a logical drive letter, then you can select them using the multi drive select functionality Opus offers. but if they're actually on separate logical drives, then moving a folder with a lot of data under it is just not an option. Since we cannot, (feature request?) in the case where the two folders you want to search are on the 'same' logical drive, it's not THAT big a deal to temporarily move the two folders to a common parent dir and just search that parent folder. Well, I've seen various ppl here on the forums like John ask if we can directly select multiple distinct 'folders' for a dupe file search operation (like we can for multiple logical drives).
