Sometimes after you bought a new personal computer (pc) or laptop, you need to check if the specification that has promised by the seller is correct appropriate with what have been installed in your pc or laptop.

One of the way to check what have installed in your pc or computer is using System Information for Windows (SIW). You can System Information for Windows (SIW) freely from http://www.gtopala.net/download/siw-setup.exe (4.05 mb).

By using the software, you can get information in detail about your laptop or pc, such as:

FileAlyzer is a tool to analyze your files. FileAlyzer allows a basic analysis of files (showing file properties and file contents in hex dump form) and is able to interpret common file contents like resources structures (like text, graphics, HTML, media and PE).

In General tabs you can find:
Location: The location where this file resides. It means the full path for the folder you stored the file in. If you want to open an Explorer window that shows this folder and file, click the Jump button displayed at the bottom left of each dialog. Size: The size this file takes in bytes. Version: If the file is some kind of program or program library, it may have a version. In that case, this version is displayed here. CRC-32: this is something the original properties dialog doesn’t offer. A CRC is a checksum that can identify a file with very high probability. If you wonder if two files are the same or not, you can compare their checksums instead of a whole file which may be many MBs in size. MD5: this is similar to CRC-32, just that MD5 (Message Diggest 5) is a newer and safer checksum. Read only: if this flag is set, a file will be treated as locked, and some applications won’t be able to write to it, others will request confirmation of your intention with additional dialog boxes. Hidden: hidden files are usually not displayed in Windows Explorer, unless you change its display options. Files are usually hidden for one of two purposes: 1. hiding configuration files from users to not confuse them, or 2. hide files the user doesn’t want others to see. System file: files flaged as system files are usually necessary for normal system operation and should be regarded as very sensitive. Directory: you shouldn’t find this flag set, as FileAlyzer will only open files, not directories (folders). Archive: a very old flag that indicates if a file has changed since the last time it was backed up. As most people neglect backups, you’ll most probably find this flag with nearly everyone of your files. Symbolic link: Time stamp: if some application displays only one file time, it will be this one. It should be the same as the Last write field. Creation: the date and time this file was created. Last access: the date and time you have accessed this file the last time. Access means for example displaying it. Last write: if you did not only display a file, but also modify and save it, this date and time is represented here.

In OpenSBI tabs, you can find:
Filesize, timestamp [file], md5, crc32, exists [authx509].

You can download this FileAlyzer (2.85 mb) from this website:
