MinGW - Minimalist GNU for Windows
MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.
CrystalDiskInfo
CrystalDiskInfo is a HDD/SSD utility software which supports S.M.A.R.T and a part of USB-HDD. Important Notice Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. Therefore, this project needs more development funds. As to current status, this project is extremely short of funds and is in desperate need of your donations. If you want to contribute to supporting the continuance of this project, please make donations by Paypal . Please make the amount of each contribution $10 USD or more (in JPYen, 1000Yen or more) if possible. Your contributions will be deeply appreciated.
FFFTP
FFFTP is lightweight FTP client software. FFFTP has many useful feature such as directory mirroring, character encdoging conversion, Firewall and SOCK, one-time password support, and so on.
Manjaro Linux
Manjaro is a user-friendly Linux distribution based on the independently developed Arch operating system. Within the Linux community, Arch itself is renowned for being an exceptionally fast, powerful, and lightweight distribution that provides access to the very latest cutting edge - and bleeding edge - software. However, Arch is also aimed at more experienced or technically-minded users. As such, it is generally considered to be beyond the reach of those who lack the technical expertise (or persistence) required to use it. Developed in Austria, France, and Germany, Manjaro provides all the benefits of the Arch operating system combined with a focus on user-friendliness and accessibility. Available in both 32 and 64 bit versions, Manjaro is suitable for newcomers as well as experienced Linux users. For newcomers, a user-friendly installer is provided, and the system itself is designed to work fully 'straight out of the box'.
CrystalDiskMark
CrystalDiskMark is a disk benchmark software. Important Notice Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. Therefore, this project needs more development funds. As to current status, this project is extremely short of funds and is in desperate need of your donations.

Virus Detection Feature on Project File Release
2018-06-26 05:01: System side will now perform Virus scan for files that are uploaded on project's file release. Scan result will be shown on the pages of a release list and such. For virus scanning, VirusTotal ( https://www.virustotal.com/) is used. VirusTotal checks for viruses by using multiple Virus detection engines in aggregated manner. Among these engines, there are a few very sensitive ones that frequently send false positives . Therefore, in rare occasions, virus warning message may appear against a practically and absolutely safe file. (Thus, even with the scan result from VirusTotal, the file cannot be immediately determined as dangerous.) Please review the detailed result to judge its safety. Also, this feature does not guarantee that a file is free of Virus infection, with its scan result. When there are a certain number of warnings as a result of detecting viruses, the result will be notified to the administer of the file project and the person in charge of the file release, by email. (Because a recheck may be performed after a certain period of time, there are cases that you may receive multiple notifications for a single file. ) If a file is judged to have a problem, the site admin side may make necessary measures such as making it private or deleting it. Due to the size limit on VirusTotal's API, virus scan for files that are over 350MB cannot be performed. Scan result will not be displayed immediately after the upload. (Due to the behavior of the VirusTotal, and the API's access limit, it will take at least 30 minutes, and there are even cases that could take a few days.)

New On Subversion Feature, Option Settings that allow Modification of Revision Properties
2018-05-10 13:44: On Subversion Feature, we have added the option settings that allow modification of revision properties. If you allow modification of revision properties, project members then will be able to revise and change commit related data, such as commit message, date, and author, after the submission of the commit. This option will be quite useful when you want to revise a commit message afterward or want to move a Subversion repository from another site by using a tool such as svnsync.
