How do I minimize the 2 25G MDF files!?

Let me tell you! Because the landlord is a single file, the landlord can't compress this file smaller with winrar, and the same can't be done with other compression software, because winrar is the pioneer of compression software at present. If compressing to the ideal size doesn't seem to work, we'll have to use another method, using the compression software's volume compression!

Divide this large file into several pieces so that it can be easily uploaded. It is recommended to divide it into 700m volumes, so that there are not many splits, which is easy to manage. Hopefully, landlord! Beg.

You can compress a compressed file in volumes so that individual files are eligible for upload. The compression method is as follows: Right-click the file (folder) you want to compress - "winrar" - "Add to archive" - in the bottom left of the pop-up compression interface, there is an item such as "split volume, number of bytes (v)", as long as you enter the number of bytes of a single file in this item, then the compression process will automatically divide the file for you.

Conversion of bytes: 1024 bytes = 1K, 1024K = 1MB, 1024MB = 1GB. You can adjust the size of the compressed package according to the size limit of the transfer tool you are using, note that the compression interface requires the input of bytes, so you need to calculate it according to the formula I provided above.

MDF file is the main database file format used by Microsoft SQL Server, an enterprise-level database program; Used with SQL

server database files installed with related add-ons; Users can also create custom MDF files.

So to open an MDF file, you can use Microsoft SQL Server software to open it, and the following are the specific steps:

1. After opening the Microsoft SQL Server software, right-click the left side of the Microsoft SQL Server interface.

select "attach" after "databases". Note: Microsoft SQL Server should be opened as an administrator.

2. Enter the "Attach Databases" interface and click the "Add" button to select the MDF file you want to open.

3. Find the MDF file you want to open in the selection interface and double-click to confirm. Here it is written as "document".

for example. 4. An extension file will be added after the selected MDF file, which is normal. Then hit enter one more time.

Gong opened the file.

When using the MDF file loaded directly, it will run automatically and does not require a CD-ROM. In addition, decompression software such as WinRAR also supports opening MDF files. Finally, it should be noted that there is usually an MDS file and an MDF file in the same directory, so be sure to put both files in the same directory, because the MDF file needs to be paired with the MDS file to be used.

Commonly used software to open mdf files are: Daemon Tools, Alcohol 120%, WinMount, Oriental Optical Drive Magician, etc.

Insert the image file into the virtual drive, and the file will run automatically, so there is no need to burn the disc.

The virtual drive file suffix is named. iso,*.cue,*.

bin*.cif,*.fcd,*.

tao,*.dao,*.dfi,*.

img,*.ccd,*.mgd,*.

mdf,*.mds,*.cdi,*.

nrg,*.VCD can also use WinRAR to decompress, move the mouse to the file with the suffix MDF or MDF, then click the right mouse button, select the open method, and then select WinRAR, after the selection, the WinRAR file extraction interface will appear, and then click "Extract to" (select a folder to decompress) so that the MDF file is decompressed.

Renamed to. iso and then directly unzip it.,I've tried it.,Guaranteed to work!!

Directly change the MDF file point attribute to ISO on it, you can play directly with the emulator, the MDS file is just a boot file There is no practical meaning, the disk is available, and the ISO file can also be changed back to an MDF file!!

The screenshot you gave is a RAR file, according to you to extract it to get the MDF and MDS files? Then you've got the image of the disc.

Image files are ......... in many different formatsISO is one of the most common of these, and MDF is another ...... that is very commonEveryone usually calls disc images ISO because in the early days, basically all disc images were ISO format ......It's just a matter of getting used to it.

If you're just playing games, you can use a virtual drive to load the MDF file (most virtual drives support at least ISO and MDF formats).

If you want to convert to ISO format, find a burning software, use a virtual optical drive to read the MDF file, and then burn it into an ISO image in the programming software.

Ultraiso is a virtual optical drive, while MDF is the storage file for the SQL Server database.

So, UltraISO can't open MDF files.

You should use the SQL Server Manager tool Attachment Database before you can view the data contents.

Each MDF file should have an MDS file associated with it, and you can load the associated MDF file by opening it directly with a virtual drive tool such as Ultraiso or Deamon Tools.

UltraISO 9 can be opened directly. MDF file, not required. mds。

1.Click File — Open, Select. mdf。

If you just want to convert to. ISO file, which can be converted directly with MDF to ISO.

1.Click to open and select. MDF file; Click Save and select the one you want to generate. ISO file.

2.Point conversion.

Use mdftoiso to handle. MDF is converted to a decompressible standard. ISO file.

2.Click the first "SELECT" button to select. MDF file, and then click the "Convert" button.

3.After the conversion, you can load it with WinCdemu virtual drive software, or use WinRAR decompression software to decompress it.

Hello, first of all, you need to install the "Alcohol 120%" software, after installing it, you open the virtual drive software, and then select Find Image File, find the location of your file. Double-click on my computer, double-click on the virtual CD drive inside and you should see the song pulling. Next, copy it to the hard drive you want to copy!

Hehe. Bonus points!

After opening the song with Qianqian Jingting, select the song and right-click to select "Convert Format", and then you can grab the CD to the hard drive.

mdf is a kind of image file that should also have a suffix named. MDS sibling files, only a few kb in size, are generally used to open MDF files directly with Daemon Tools. If the image file is corrupted, you need to create a new folder, copy the mdf and mds files to the new folder, and then use daemon tools to simulate the mds file, and then you can install it.

For example, if I have an image named : Then there should be a file named :, which I can read by using daemon tools to simulate the mdf file, but if an error message appears.

Then you need to create a new folder, let's say "abc".

Copy the two files to the folder "abc" and use daemon tools to simulate the files.

If you still don't understand, you can go to this address to take a look.

Dizzy, isn't it detailed enough? Handful. MDF and. MDS files in the same folder, then open Daemon Tools, right-click - load image - find your folder - double-click on that. MDF file on it.

1. Install Daemon Tools Lite, you should be prompted to restart the installation, and you can install it once after restarting.

2. Click Daemon Tools Lite in the lower right corner of the computer, click the left button, the one where the device is empty, open the folder where the MDF is located, and select the largest one.

3. Open "My Computer", you will see that a CD-ROM drive letter has been added to the CD-ROM position, which is the installation file, and you can install the MDF file.

It's very simple, just like the standard ISO method, when selecting files, you can select all files in the "File Type" below, which you can see when you open the window again. MDF file, select Import.

First open the virtual optical drive tool, open the menu in the lower right corner, select the virtual mirror file, you can download the Chinese version, I used this to play Battlefield 2, also MDF file.

Start by creating a virtual disk.

Then right-click "Add Image" and browse to find your MDF file.

Then I can see a disk on my computer with the image on it.

It is recommended that you still use the software WinMount, which is free of charge and powerful. Much more convenient than other software.

Not only can it be used as a virtual optical drive, but it can also be opened virtually as a hard disk, so that for some particularly large compressed files, you don't have to wait for slow decompression before using it.
