    <p>Here is a barebones code that will synchronize two directories if they have the same structure within the directory.</p> <pre><code>import shutil import os #Assuming your folders are identical for synchronization purposes root_src_dir = "Path\To\Source" root_dst_dir = "Path\To\Dest" for src_dir, dirs, files in os.walk(root_src_dir): dst_dir = src_dir.replace(root_src_dir, root_dst_dir) if not os.path.exists(dst_dir): os.mkdir(dst_dir) for file_ in files: src_file = os.path.join(src_dir, file_) #dst_file = os.path.join(dst_dir, file_) #Decides whether or not to replace files in the destination if os.path.exists(os.path.join(root_dst_dir,dst_file)): #EDIT HERE. continue else: print "Copying", dst_file shutil.copy(src_file,os.path.join(root_dst_dir,dst_file)) #EDIT HERE </code></pre> <p>This will automatically create a "copy" of the source directory to the destination directory. It will create subdirectories that are missing and copy files in those specific locations to the destination directory only if the file does not yet exist in the destination. </p> <p>If you want make sure files are identitcal or not, then you'll probably want to look into <a href="http://docs.python.org/2/library/filecmp.html" rel="nofollow">filecmp</a> or hashes(below) to check if you've copied the file before.</p> <pre><code>import hashlib def cmpHash(file1,file2): """ Compares two files' hashes to determine duplicates. This doesn't work out so well, possibly due to different metadata""" hash1 = open(file1,'r').read() hash2 = open(file2,'r').read() #returns true if the files are the same - otherwise, false. return hashlib.sha512(file1).hexdigest() == hashlib.sha512(file2).hexdigest() </code></pre> <p>Example: (NO LONGER TRUE AFTER EDIT).</p> <pre><code>DriveA:\SomeDirectory\SourceDirectory\-Stuff- DriveB:\DestDirectory\-Stuff- #All -Stuff- from the SourceDirectory will be copied to DestDirectory, regardless of directories infront of Source/Dest Directory </code></pre>

    1. COThe only issue I see with that, is that the files that are moved to the destination folder will be moved manually by people into other folders, so the code would be sending files it already sent.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
