NoTouch Desktop uses potentially large files of different file types. To ensure file integrity, several checks are used:
All these values are shown in the NComputing download portal, and to be sure your file is ok, you should check your local file at least for file size and one of the two checksums, MD5 or SHA1.
If a download ends prematurely, in most cases the file size will be smaller than on the NComputing server. However, it is still possible for a file to be corrupt and have the same file size. File size alone does not indicate a "good" file. It can only indicate a problem - if it differs -, but not the other way round.
Check MD5 and SHA1 on Windows
Microsoft Windows does not bring a file checksum utility by default. However, several alternatives exist:
- Microsoft FCIV  and a tutorial on how to use it 
- MD5sum for Windows 
- SHA1sum for Windows

Check MD5 and SHA1 on Mac OS
Mac OS X brings MD5 and SHA1 programs by default. Open a "Terminal" and enter these commands:
cd Downloads md5 FILE_TO_TEST.xxx
cd Downloads shasum FILE_TO_TEST.xxx
Of course you need to replace FILE_TO_TEST.xxx with the actual filename.
Check MD5 and SHA1 on Linux
All desktop Linux distributions bring MD5 and SHA1 programs by default. Open a "Terminal" (xterm/rxvt/SSH login) and enter these commands:
Of course you need to replace FILE_TO_TEST.xxx with the actual filename, and path referring to the path where the file is located (depending on Linux distribution).
