No matter how large your system you'll have access to your files instantly!
No more searching through folders or waiting hours for a search utility to slowly scan your drives.
Don't wait, step into the time warp portal which is mysys!
New in version 3
Now you can play media files, any file type VLC can play mysys can play, because it is using VLC.
Multi-select files to play them, including playlist files such as .m3u
View whole files in the View tab, you can choose Hex mode as well.
View HTML or XML files in the web browser tab, or search and browse the web.
Any 64 bit version of Windows with .Net 4.5.1 and above installed.
5-10 GB free disk space depending on total number of files, about 5 GB per 15 million.
The first thing mysys needs to do is create a database of all your files.
Great care was taken to make this process as fast as possible by scanning
separate disks simultaneously in a highly multi-threaded scheme.
If you have mapped network drives a popup will ask which ones to include in the
database. Those drives will take longer to index depending on the network connection speed.
CD/DVD/Flash drives will not be indexed, only Fixed drives and optionally Network drives.
Use the Schedule button to create a Windows Task Schedule so the indexing happens at
a time which is most convenient. To delete the task just click Cancel.
Once the database is created you are ready to find files, fast!
In the top left text box, type any filename and hit enter or click Search.
Wild cards are supported such as read*.txt.
You can use AND/OR/- like: this OR that
the - is to exclude like: this -notthat
Use double quotes like: "find this whole thing"
Use brackets like: (afoldername or anotherfolder) and (*.c or *.rc or *.h)
For that example you would check on the "Include folder names" option and probably the "Exact match" option also otherwise will find *.cs, *.css, *.hpp, etc...
Because this database is Full Text Search you need to know the first chars of the
file name, so if you're looking for filename.txt, *name.txt won't work! Without this limitation
we wouldn't be so fast! *.txt will work however. Possibly a future version will have an option for a slower
but more flexible search.
You can use the Containing text box to search within the files found. Contents are never
indexed but uses a fast highly multi-threaded algorithm.
File sizes, Dates and Attributes are all read live off the disk, these are not stored in the database.
A red tab icon means search is in progress, orange means file info being gathered in the background, wait until it's black before trying to sort by date/file size/type/attr.
You can have multiple searches by clicking the small empty tab on the right of the main tab, like Chrome or Firefox.
Use the Group checkbox to group by the sorted column, just click the column headers to change the grouping.
You can hover over image files to see a preview.
Double click on a folder name to open that folder in explorer, likewise double click file names to run or open them with associated application.
Right click files or folders to popup the system menu, the folder menu is not the same as a file menu.
Multi-select using shift or ctrl keys.
Use Drag and Drop to copy files from mysys to the drop zone.
If you want to store the database on another drive, you can create a Directory Junction.
You can find the database in C:\Users\username\AppData\Roaming\mysys
So to create a junction move the mysys folder to the drive you want then from
a cmd prompt: mklink /j C:\Users\username\AppData\Roaming\mysys D:\foldername\mysys
Or to make it easier you could install this handy tool: http://schinagl.priv.at/nt/hardlinkshellext/hardlinkshellext.html
Each user on the same computer will have his/her own database for security/privacy reasons.
/CreateDB [network drive letter(s)]
Example: mysys.exe /CreateDB X Z
This creates a database including X:\ and Z:\ network drives.
Example: mysys.exe /CancelDB
Cancels database creation deleting temporary files.
The exit code will be 0 if success, or 1 if an error occurred.

Revamped command line DB creation method, there was an issue starting the interface if DB creation underway, related to the Web Browser tab.
Now there will be a tray icon which can be clicked to open the interface, otherwise mysys will close after DB creation completes and so will the tray icon.
Created qlaunch.exe to be used by the Scheduled task, it launches mysys and closes to assure the task status isn't kept in Running state
when mysys is left open (DB underway then tray icon clicked), otherwise the Windows task scheduler won't run the next scheduled DB creation until mysys is closed.
Ver 4.0 - 11 December 2019
Added ability to view PDF's in the Web Browser tab.
Requires Adobe or compatible PDF Reader to be installed.
On windows 10 the recommended PDF viewer is Foxit Reader https://www.foxitsoftware.com/pdf-reader, it can coexist with Adobe but the default PDF viewer needs to be set to Foxit, this is because mysys needs to Run as Administrator which causes Adobe Reader to fail. Adobe is aware of the issue and hopefully they will fix it in the near future. Adobe works fine with Windows 7, 8 and 8.1.
If your PDF's do not display in the Web Browser tab please visit https://helpx.adobe.com/ca/acrobat/using/display-pdf-in-browser.html
Follow instructions for "Internet Explorer 8 and later". Use Ctrl-H to switch between Read Mode/Fit to Width.
