What is a VCH file?

VCH files mostly belong to Adobe AIR. Adobe Flash Component Cache: Most VCH files act as a cache for Adobe Flash components. They use an internal format called certificate2 to store temporary data. This cache helps Adobe AIR applications load components more quickly.
Alternate Use Cases:

Virtual Contact Sheet – Some VCH files serve as a virtual contact sheet, used by specific systems like those from ADVLC.

Bitcoin Transaction Data – In other cases, VCH files hold raw Bitcoin transaction data, associated with VLC media player.

FilExt.com notes: If you have a VCH file, check the software that created it. For Adobe Flash cache files, let Adobe AIR manage them; if the file is a virtual contact sheet or Bitcoin data file, use the corresponding application. For more details on Adobe AIR technology, visit Adobe AIR SDK.

How do you open VCH files?

You need a suitable software like Adobe AIR to open a VCH file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your VCH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a VCH file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert VCH files:

The Master Genealogist (Genealogy Chart (Older Version)) by Wholly Genes, Inc.
The Master Genealogist (or TMG) is a family history project manager. A genealogy charting add-on called Visual Chartform 2.0 uses the VC2 format. Earlier versions used VCH but there is no direct way to convert VCH files to VC2 format. If both old and new versions are running you can open a VCH file, select all and then copy to the Windows clipboard. Then, in the new version and on a blank chart, use paste and make whatever modifications are necessary. This file format is classified as Graphic.

VCH file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the VCH files:

The VCH file extension is rarely used and predominantly uses a uniform format. But the following two file formats are common:

90% of all VCH files store the data in the certificate file format. A digital certificate is a unique, digitally signed document which authoritatively identifies the identity of an individual or organization. Using public key cryptography, its authenticity can be verified to ensure that the software or website you are using is legitimate. They consist of unreadable binary data. The average file size is 450 KB with most files being between 130 KB and 630 KB in size. The file type was developed only in the last few years. Several words can almost always be found in the files, e.g. pfivxV4. A usual file name is Adobe AIR.vch or AdobeAIR.vch. These files are often associated with activex, plugin and adobecp.

All other VCH files (10%) have no uniform format. You can get all the details of your VCH file by dragging it onto this page or by clicking the button "Choose your .vch file to analyze" above.
