What are tmp*.json and tmp*.tmp Temporary Files on my Windows 7 computer? Can I remove them?

tmp*.json and tmp*.tmp Temporary Files are created by Visual Studio programs. They are located in the \Users\<userid>\AppData\Local\Temp folder.

Each time when you use a Visual Studio program, it will create a pair of tmp*.json and tmp*.tmp Temporary Files with 4 Hex digits in the middle file names. For example:

   5,159,784 tmpFE28.json
           0 tmpFE28.tmp

The tmp*.json file seems to contain a digital signature as shown below:

{"manifestVersion":"1.1","engineVersion":"1.10.104.59848","info": 
  {"id":"VisualStudio/15.2.0+26430.16","buildBranch":...
 "signature" : {
   "signInfo" : {
     "signatureMethod" : "sha256RSA_cng",
     "digestMethod" : "sha1",
     "digestValue" : "cIgGtPXSuyY07lzBLYYxo65HUrg=",
     "canonicalization" : ""
   },
   "signatureValue" : "Q+gWJweFEBMsgA0zjpnCH5JA3NkMA8t...
   "keyInfo" : {
     "keyValue" : {
       "rsaKeyValue" : {
         "modulus" : "0IfUQit+ndnGetSiw+MVktJTnZUXyVI2...
         "exponent" : "AQAB"
       }
     },
...

Yes. You can delete older tmp*.json and tmp*.tmp Temporary Files files to keep the temporary file folder clean.
