You may find that there is a file size limitation when you want to upload your files to the free plan of a certain online storage, if that’s the case, you will have to either upgrade to a paid plan, or split your file into smaller ones with a file splitter before uploading and join them back into a single file after downloading.
FFSJ is definitely the best file splitting and merging utility for MS Windows. Feature lists:
If you are fond of keeping your hard disk clean and organized, you can find and remove duplicate files with Duplicate Cleaner, search and delete duplicate or similar images with VisiPics, and erase empty folders with EFN:
EFN is a portable and lightweight program that can search and remove empty folders to the Recycle Bin, you can make it integrated with Windows Explorer.
RED is a freeware created to delete all empty directories recursively under a root folder. It can treat directories as zero size ones if they only contain empty files, .tmp files, thumbs.db and desktop.ini files.
RED supports most common 32-bit and 64-bit Windows OSes.
RED is a 395KB download available from SourceForge.net, it requires Microsoft .NET Framework 3.5 or later.
As we previously mentioned, Duplicate Cleaner is the best yet free software for scanning and removing duplicate files on your hard drive, it’s packed with many features that most shareware do not have, where it really shines is that it compares files using md5( SHA-1, SHA-256 ) checksum, and supplies you a powerful selection assistant. If you have several large duplicate files, or many small duplicate files, calculating MD5 checksums first then only comparing the hexadecimal number will take significantly less time than doing a byte to byte compare on each pair of files which have the same size.
Duplicate Files Finder( there’re many software have this name ) is an open source project, it’s written in c#, it allows you find any duplicate files on your computer and delete them or move to recycle bin.
Once you have added the folders for scanning and pressed go, Duplicate Files Finder will scan all files recursively in all subdirectories, generate the md5 checksums and compare them.
Duplicate Files Finder supports file filter, and allows you exclude files less/more than a specified size, you can delete file via the right button menu.
Duplicate Files Finder works on Windows 7 and Windows XP.
To compare two single file, you can use WinMerge or just the Windows command FC, but if you desired to compare files in two folders/directories including tens or hundreds of items, this could be a real challenge, it will make you crazy if you do it manually. MD5Summer is a simple and yet practical folder compare freeware, which can gets the jobs done and saves a lot of time for you.
MD5summer has been designed to generates and verifies md5 checksums for multiple files or folders, as we all know, every file has a unique md5 hash value, if two files have the same md5 value, they have the same content. Thus we could use MD5summer to generate md5 checksums for one directory and store the results in a plain text file, then verify md5 checksums for another directory use the previous saved text file. This is especially useful if you want to find the difference between the backup files and the files on your harddisk, or two folders which have different version.
MD5Summer is portable, to use it just download and extract the package, the click md5summer.exe to launch it, first we select a folder and click “Create Sums”,
then we click “Select All” and “Add recursively” to add all the files and subfolders in the root folder, then press OK,
MD5Summer will generate and display all the MD5 hash value for each file, you can then save the result in a text file.
Now we go back to the main panel, choose another folder and press “Verify sums”, then select the checksum text file.
MD5Summer will then list the files which are not same with red icon and the others with green icon.
IMPORTANT: Files that have different file name will be treated as another file, for these ones you can use Duplicate Cleaner to scan and mark the duplicate files.
MD5Summer works on the following operating systems: Microsoft Windows 7/Windows XP/Win95/98/2000/NT and is available as a free download here: http://download.cnet.com.
KDiff3 is a free cross-platform file compare and merge utility that works on Windows 7, Windows XP, Mac as well as Linux. Whether you are a software developer or a website programmer, you may find it useful and handy.
It’s a good idea to compare files and directories using the 5 Best MD5/SHA-1 checker we’ve rounded up for you, then ignore the files which are identical.
You can use KDiff3 as an alternative to WinMerge( free ), Beyond Compare or UltraCompare Professional.
KDiff3 is a 7.5MB download available from SourceForge.
