 This program helps you sorting your files. First of all, the **files are copied to own folders for each file type**. Second, **jpgs are distinguished by the year** when they have been taken **and by the event**. We thereby define an event as a time span during them photos are taken. It has a delta of 4 days without a photo to another event. If no date from the past can be detected, these jpgs are put into one folder to be sorted manually.
 
-All directories contain maximum 500 files. If one contains more, numbered subdirectories are created. If you want another file-limit, e.g. 1000, just put that number as third parameter to the execution of the programm: ```python recovery.py <path to files recovered by Photorec> <destination> 1000```

 ## Usage
 
 ```python recovery.py <path to files recovered by Photorec> <destination>```
 
 This copies the recovered file to their file type folder in the destination directory. The recovered files are not modified. If a file already exists in the destination directory, it is skipped. Hence you can interrupt the process with Ctrl+C and continue afterwards.
 
+The first output of the programm is the number of files to copy. To count them might take some minutes depending on the amount of recovered files. Afterwareds you get some feedback every ~2000 processed files.
