In the folders list right click a folder and choose 'Disable Automark For This Folder'.
You can exclude files by extension or a phrase in the file name by using the option Advanced->Do not auto mark files with:
Use the option 'Move Checked Files' by selecting first a target folder. Fast Duplicate File Finder will recreate the folder structure of the duplicate files in the target folder and move your duplicates there.
Please read this small article on the topic "Which duplicate file finder to choose?"
Fast Duplicate File Finder has an option to protect your system files and folders which is enabled by default. Either move your files outside the protected folders or disable the option. Please note that the data on your desktop is also considered as protected in order not to delete duplicate icons and applications that may reside on the desktops of the other user accounts on your machine.
The other possible reason for the application not to identify certain files is that you may have set filters. Make sure that the filtering button is not pressed (down) - the button with the funnel icon on the toolbar. If it is pressed just click it once - this will raise the button denoting that the filtering is no longer active. Clicking it again will bring up the filter settings dialog.
If you have moved the files to a folder just go to the root of that folder and copy the files and/or directories to the root of the corresponding drive that they belong to.
If you have deleted the files to the Recycle Bin explore its content, select all the files and/or folders inside and by right-clicking the selection choose the "Restore" pop-up menu item.
If you have permanently deleted the files there is not much to be done. You still have chances to restore some data by using an undelete/un-erase application though the chances are really low. You can Goggle to find such application on the web. Use your computer as less as possible until your try the undelete applications as the deleted data may be overwritten and permanently damaged. The space that the deleted data was occupying is now marked as free and the next write operation may use it.
FDFF performs a pre-scan analysis in order to quickly weed out the files that are not duplicates. The information above denotes that FDFF has checked 114 out of the total 176 files that it needs to check deeper. The total 2261 files are included in the analysis.
Some files are listed and the following message appears: "Some files could not be deleted or moved and will remain checked in the list. Make sure they are not in use or located on a read-only media and retry."
As pointed in the message FDFF can not delete the files because, they are either in use and locked by another application or they are located on a read-only media like CD-ROM. There is nothing that you can do in the second case as you can not delete files from a CD-ROM. In the first case you can save the project file and restart your computer. Before starting any other processes (that may open and lock your files), start FDFF, load the project and try to perform the delete operation again. If you still have files that are in use these may be ones used by your operating system (we do not recommend deleting such files) or they may be in use by applications that are in your startup list and have been loaded during boot time. You can locate and disable such applications and retry.
Generally the duplicate file finder should not crash or freeze, but due to the huge amount of data that the application processes it is possible to find damaged files in your system that cause problems. What you can do?
Can not move (code: XXX): [filename]
183 (B7) - MAX_PATH was exceeded during the operation. The maximum path length in Windows is 260 characters and moving the corresponding file will produce a path longer than the limit. Reduce the length of your folder/file names and retry.
